 CHAPTER 1: EXECUTIVE SUMMARY
Pesticides are used to protect the crops from insects, germs and rodents when the plants are
growing up. Residual amount of these chemicals are present on the food when it gets to the
grocery store. The pesticide residue cannot easily be removed with plain water. When you
consume a fruit, the pesticide residue goes into the body as they get stuck and can make you
sick. Read on to found out the harmful effects of pesticides.

Pesticides are chemical substances used to kill pests that might damage the crops and fruits. It
is used in abundance by farmers, especially in remote areas. The developments in the
agricultural sector have evidently shown an increase in the use of pesticides during the
cultivation of crops.

There are numerous health hazards linked to the use of pesticides. Pesticides can have grave
effects on the health of anybody consuming fruits or vegetables highly contaminated with
pesticides.

Several reports suggest that high levels of pesticides in food can lead to the development of
diseases such as cancer, kidney and lung ailments. Children have developing organs, prone to
catching infections and diseases.

Any exposure to these high chemical residues can lead to childhood cancers, mental health
problems such as autism and attention deficit hyperactivity disorder.

If a pregnant woman eats a fruit containing pesticides residue, the fetus might get affected and
she may face birth complications. Some other health risks associated with these harmful
chemicals include nausea, diarrhea, abdominal cramp, dizziness and anxiety.

Some of the fruits and vegetables that have higher concentrations of pesticides are fruits like
peaches, nectarines, cherries, strawberries, grapes, raspberries, pear and apples. Potatoes,
spinach, bell peppers and celery are some of the vegetables that contain pesticide residue.

8
 CHAPTER 2: OVERVIEW OF THE COMMUNITY

Most fruits produce a gaseous compound called ethylene that starts the ripening process. Its
level in under-ripe fruit is very low, but as the fruits develop, they produce larger amounts of
the chemical that speeds up the ripening process or the stage of ripening known as the
“climacteric.”

Recent studies have shown ethylene regulates the expression of several genes, which are
involved in fruit ripening. These enzymes convert complex polysaccharides into simple
sugars and make the skin of the fruits soft. In artificial ripening, this process is mimicked
using chemicals.

The most commonly used chemical is called ethephon (2-chloroethylphosphonic acid). It

penetrates into the fruit and decomposes ethylene. Another chemical that is regularly used is
calcium carbide, which produces acetylene, which is an analogue of ethylene.

It is explosive in nature and studies have shown that it breaks down the organic composition
of vitamins and other micronutrients. Besides, it changes only the skin colour: the fruit
remains raw inside.

In addition, industrial grade calcium carbide is often found contaminated with trace
amounts of arsenic and phosphorus, which are toxic chemicals.

9
Chemicals are used in fruits and
vegetables Benefits of pesticides

Food crops must compete with 30,000 species of weeds, 3,000 species of worms and 10,000
species of plant-eating insects. And threats don’t stop once crops leave fields – bugs, molds
and rodents can all cause damage in storage. Pesticides can prolong the life of crops and
prevent post-harvest losses.

Currently, about 925 million people around the world – one is seven of us – are going hungry.
To reduce hunger, we need to increase food productivity. Pesticides help farmers do that.

Pesticides enable farmers to produce safe, quality foods at affordable prices. They also help
farmers provide an abundance of nutritious, all year-round foods, which are necessary for
human health.

Fruits and vegetables, which provide essential nutrients, are more abundant and affordable.
Grains, milk, and proteins which are vital to childhood development are more widely
available because of lower costs to produce food.

10
Nicotine Sulphate Nicotine is extracted from tobacco or related Nicotine species and is one
of the oldest botanical insecticides in use today. It’s also one of the most toxic to warm-
blooded animals and it’s readily absorbed through the skin. (Wear gloves when applying it,
follow label directions and keep pets away from application areas.) It breaks down quickly,
however, so it is legally acceptable to use on organically grown crops.

Nicotine sulphate is sold as a 40 percent nicotine sulphate concentrate under trade names that
include Black Leaf 40 or Tender Leaf Plant Insect spray. Nicotine kills insects by interfering
with the transmitter substance between nerves and muscles. It's commonly used to control
aphids, spider mites and other sucking insecticides on most vegetables, some fruits, flowering
plants and ornamental shrubs and trees. Spider mites and other sucking insecticides on most
vegetables, some fruits, flowering plants and ornamental shrubs and trees. Roses are sensitive
to nicotine.

Nicotine sulphate has a DANGER warning.

Sulphur

Sulphur can be used as a dust, wettable powder, paste or liquid. Its primary use is to control
powdery mildews, certain rusts, leaf blights and fruit rots. Spider mites, psyllids and thrips
also are susceptible to sulfur. Most pesticidal sulphur is labelled for vegetables such as beans,
potatoes, tomatoes, peas and fruit crops such as grapes, apples, pears, cherries, peaches,
plums and prunes

11
Sulphur has the potential to cause plant injury in dry 90 degree-plus weather. It's also
incompatible with other pesticides. Don't use sulphur on plants within 20-30 days of applying
spray oils. Sulphur reacts with the oil to create phytotoxicity.

Sulphur is non-toxic to mammals, but it may irritate eyes and skin.

Lime sulphur

Lime sulphur is made by boiling lime and sulphur together. The mixture is used as a dormant
spray on fruit trees to control diseases such as blight anthracnose, powdery mildew and some
insects including scales, thrips and eriophyid mites. Its drawbacks include its rotten-egg smell,
its potential to burn exposed skin and eyes and to injure plants if applied when temperatures
exceed 80 degrees F. Lime sulphur has been assigned a DANGER rating.

Pesticides help farmers to produce more with less land

With the introduction of pesticides, farmers have been able to produce bigger crops on less
land, increasing crop productivity by between 20 and 50 percent. In addition, pesticides allow
farmers to maximize the benefits of other valuable agriculture tools, such as high quality
seeds, fertilizers and water resources. Pesticides are therefore indispensable tools for
sustainable production for high quality food and fibers.
Pesticides ensure bountiful harvests
Numerous scientific studies show that eating fruit and vegetable regularly reduces the risk of
many cancers, high blood pressure, heart disease, diabetes, stroke and other diseases.
Pesticides help keep food affordable
Farmers grow more food on the same land with the help of pesticides. Studies have shown
that growers of organic vegetables spend significantly more on hand weeding compared to
growers who use herbicides. This explains why organic food is more expensive than
conventionally grown food.
Pesticides help reduce waterborne and insect transmitted disease
Such as malaria, Lyme disease and West Nile virus. Pesticides contribute to enhanced human
health by preventing disease outbreaks through the control of rodent and insect populations.
Pesticides help conserve the environment

They enable farmers to produce more crops per unit area with less tillage, thus reducing
deforestation, conserving natural resources and curbing soil erosion. Pesticides are also
critical for the control of invasive species and noxious weeds.

12
Herbicides have removed the hardship of hand weeding

This means farming families across the world have the choice to pursue education and
opportunities away from farming, thus improving quality of life and living standards

Pesticides have transformed developing countries into food producers

Crop protection products have helped farmers in the developing world grow two or three
crops a year, so much that these countries can become ‘breadbaskets’ for the rest of the world.
The food exports benefit people in temperate countries with shorter growing seasons.

Securing what’s in storage

Even after the crop is in, it can be subject to attack by pests. Bugs, moulds, and rodents can
harm precious grains. Pesticides used in stored products can prolong the viable life of the
produce, prevent huge post-harvest losses from pests and diseases and protect the grain so it is
safe to eat.

Pesticides help in an abundant harvest

By using pesticides it ensures that crop is protected by pests and are healthy for harvest.
Pesticides ensure crops are not damaged and not infected by any pests.

 CHAPTER 3: COMMUNITY SERVICE PART

Types of exposure to chemicals and pollutants

There are 3 ways to be exposed to chemicals and pollutants:

 Inhaling (breathing in)

 Absorption (skin and eye contact)
 Ingestion (eating and drinking)

Inhaling

You are exposed to chemicals and pollutants when you inhale (breathe in). You take over
20,000 breaths a day. This number can be much higher for infants and children. The
chemicals and pollutants you inhale can end up in your lungs and blood stream. Sometimes,
you can smell or taste harmful chemicals, but it isn’t always so easy. Some chemicals, like
radon or carbon monoxide, are odourless, tasteless and invisible

Absorption

You can be exposed to chemicals and pollutants by coming into contact with them through
your skin and eyes. These organs can be more sensitive to chemicals and may react more
quickly than the rest of your body.

Ingesting

You’re exposed to chemicals and pollutants when you eat and drink. Chemicals and pollutants
are found in both our food and water sources.

Potential health effects

Incorrect use of household chemical products may cause immediate health effects, such as
skin or eye irritation or burns, or poisoning.
There can also be longer-term health effects from chemicals. When these occur, they’re
usually the result of exposure to certain chemicals over a long period.
Depending on the chemical, longer-term health effects might include:

14
 Cancer
 Organ damage
 Weakening of the immune system
 Development of allergies or asthma
 Reproductive problems and birth defects

Effects on the mental, intellectual or physical development of children.

At the Store or Market

 Choose produce that isn’t bruised or damaged.

 If you buy pre-cut fruits and vegetables choose items that are refrigerated or kept on ice
 Separate fruits and vegetables from raw meat, poultry, and seafood in your shopping cart and in
your grocery bags.

At Home

Wash your hands kitchen utensils, and food preparation surfaces, including chopping boards
and countertops, before and after preparing fruits and vegetables.

Clean fruits and vegetables before eating, cutting, or cooking, unless the package says the
contents have been washed.

Wash or scrub fruits and vegetables under running water—even if you do not plan to eat the
peel. Germs on the peel or skin can get inside fruits and vegetables when you cut them.

Washing fruits and vegetables with soap, detergent, or commercial produce wash is not
recommended. Do not use bleach solutions or other disinfecting products on fruits and
vegetables.

Cut away any damaged or bruised areas before preparing or

eating. Dry fruit or vegetables with a clean paper towel.

 Keep fruits and vegetables separate from raw foods that come from animals, such as
meat, poultry, and seafood.
 Refrigerate fruits and vegetables within 2 hours after you cut, peel, or cook them (or 1
hour if exposed to temperatures above 90°, like a hot car or picnic). Chill them at 40°F or colder in
a clean container

15
 Removing pesticides from fruits and vegetables

With food prices skyward bound and no reprieve from pesticide residues in fruits and vegetables,
fresh fruits and vegetables will soon become a luxury item for those who can afford chemical
free and organic products.

The source for pesticide residues in our food could be through the application of pesticides on
crops, with residues remaining in the fruits and vegetables or through the application of
pesticides in homes to disinfect. Pesticide residues, once in our system can be the cause for
several acute and chronic diseases. So removing the pesticides, as much as we can, is the first
step forward

As consumers we do not have any control on the pesticides that is sprayed on fruits and
vegetables in the farms but there are some quick do-it-yourself techniques that can help us get
rid of the residues to a large extent.

The National Institute of Nutrition (NIN), released the Dietary Guidelines for India recently. The
guidelines has introduced some simple steps which should be adopted by every household to
remove the pesticide residual contamination. These easy steps should be cast in stone in every
household.

WASHING

 The first step in the removal of pesticide residues from the food products is washing.
Washing with 2% of salt water will remove most of the contact pesticide residues that
normally appear on the surface of the vegetables and fruits.
 About 75-80% of pesticide reduces are removed by cold water washing. The pesticide
residues that are on the surface of fruits like grapes, apples, guava, plums, mangoes,
peaches and pears and fruity vegetables like tomatoes, brinjal and okra require two to
three washings.
 The green leafy vegetables must be washed thoroughly. The pesticide residues from green
leafy vegetables are removed satisfactorily by normal processing such as washing
blanching and cooking.

16
 Blanching

A short treatment in hot water or steam applied to most of the vegetables. Certain pesticide
residues can effectively be removed by blanching. But before blanching it is very important
to thoroughly pre-wash the vegetables and fruits.

Peeling

Both systemic and contact pesticides that appear on the surface of the fruits and vegetables can be
removed by peeling.

Steps such as concentration, dehydration and extraction from the raw product can further reduce
pesticide residues in the end product. The net influence of processing almost always results in
minimal residues in processed food

Objectives of the Activity done: To collect data and information about use of chemicals on
fruits and vegetables

Detailed Report:

In this week, our project guide made a team with 4 members to do community service
project in Eluru, Andhra Pradesh. We selected a topic “USE OF CHEMICALS ON FRUITS
AND VEGETABLES”.

In this topic we are considering some of the fields to gather full information about use
of chemicals.

In the first week, we (our team) collectively went to the community to outlook the
condition and situation of a particular fruit.

What we found in the area are

In that area most of the farmers are using chemicals to cultivate the crop
Also most of the farmers using high amount of fertilizers and pesticides for better production.

Nowadays fertilizers and pesticides are mostly used and there is no increase in organic
farming.

Also, we done a survey of some farmers in the village for asking some prepared questions
to the farmers and noted their answers which are attached in chapter 5.

Time duration: 64 hours spend in first week.

WEEK -2 (From Dt 23-07-2022 to Dt 30-07-2022)

Objectives of the Activity done: surveying and collecting data.

Detailed Report:

In this second week, We (team) continued surveying the remaining farmers in

Kaikaram village.

When compared to first week, we had lot of experience with farmers while
conducting survey in village. The experience is

The farmers cultivate the crops based on the type of the land.
We learned about, time taken by growing of a crop. Also we learned about the fastest
growing crop and slowest growing crop.
We learned about, which fertilizers are used for the particular problem.
By the usage of needed fertilizers we can reduce the problem.
We learned about multiple cropping. And profits earned by the farmers based on multiple
cropping.

Multiple cropping:

Cultivating two or more crops at the same time in the same field. When multiple
crops are grown simultaneously this is also known as inter cropping. Is increases the
harvests, export and foreign exchange, It uses in maintaining and improving the soil
fertility

We also completed the survey. We are taken the survey around 10 members in the village.
The response of the village is good and they are very much interested to knowing this
information and trying to implement it.

Time duration: 64 hours spend in first week.

Objectives of the Activity done: Community awareness campaigns conducted.

Detailed Report:

In this fourth week, we have conducted totally 6 campaigns in nearby schools.

During the survey, we realised firstly to creating an awareness in the children. So, we
conducted an awareness campaign in Eluru government school. We gave awareness program to
9th class students.

The speech is given by us about use of chemicals on fruits and vegetables is

After knowing about the student’s knowledge regarding the use of chemicals on fruits and
vegetables. We make a proper note. We lecture them why farmers are using chemicals while
cultivating the fruits and vegetables.

Importance of fruits and vegetables:

Fruits and vegetables are a good source of vitamins and minerals.

They are an excellent source of dietary fibre, which can help to maintain a healthy gut and
prevent constipation and other digestion problems.

Uses of fertilizers:

-> Plant nutrients ensure we can grow enough crops for our growing world.
-> Fertilizers can help farmers adapt to climate change and operate in water-scarce environments.
-> Nutrients management helps mitigate climate change by increasing soil carbon sequestration.
-> Fertilizers are key for sustainably intensifying agriculture on existing land
-> Fertilizers help prevent and reverse soil degradation and desertification.

Time duration: 24 hours we spend in the project.

 Describe the problems you have identified in the

community Impact on environment

Pesticides can contaminate soil, water, turf and other vegetation. In addition to killing insects or
weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial
insects, and non-target plants. Insecticides are generally the most acutely toxic class of
pesticides, but herbicides can also pose risks to non-target organisms.

Surface water contamination

Pesticides can reach surface water through runoff from treated plants and soil. Contamination of
water by pesticides is widespread. The results of a comprehensive set of studies done by the
U.S. Geological Survey (USGS) on major river basins across the country in the early to mid- 90s
yielded startling results. More than 90 percent of water and fish samples from all streams
contained one, or more often, several pesticides. Pesticides were found in all samples from
major rivers with mixed agriculture and urban land use influence and 99 percent of samples of
urban streams. The USGS also found that concentrations of insecticides in urban streams
commonly exceeded guidelines for protection of aquatic life.

Ground water contamination

Ground water pollution due to pesticides is a worldwide problem. According to the USGS, at
least 143 different pesticides and 21 transformation products have been found in ground
water, including pesticides from every major chemical class. Over the past two decades,
detections have been found in the ground water of more than 43 states.

During one survey in India, 58% of drinking water samples drawn from various hand pump
and wells around Bhopal were contaminated with Organo chlorine pesticides above the EPA
standards. Once ground water is polluted with toxic chemicals, it may take many years for the
contamination to dissipate or be cleaned up. Clean up may also be very costly and complex, if
not impossible.

Soil contamination

A large number of transformation products from a wide range of pesticides have been
documented. Not many of all Persistency and movement of these pesticides and their TPs are

field. constant, the octanol/water partition coefficient, and half-life in soil. Pesticides and TPs
could be grouped into: Hydrophobic, persistent, and bioaccumulable pesticides that are
strongly bound to soil. Pesticides that exhibit such behaviour include the organochlorine
DDT, endosulfan, endrin, heptachlor, lindane and their TPs.

Effect on soil fertility

Heavy treatment of soil with pesticides can cause populations of beneficial soil
microorganisms to decline. According to the soil scientist Dr. Elaine Ingham, “If we lose both
bacteria and fungi, then the soil degrades. Overuse of chemical fertilizers and pesticides have
effects on the soil organisms that are similar to human overuse of antibiotics. Indiscriminate
use of chemicals might work for a few years, but after a while, there aren't enough beneficial
soil organisms to hold onto the nutrients”. For example, plants depend on a variety of soil
microorganisms to transform atmospheric nitrogen into nitrates, which plants can use.

Common landscape herbicides disrupt this process: triclopyr inhibits soil bacteria that
transform ammonia into nitrite glyphosate reduces the growth and activity of free-living
nitrogen-fixing bacteria in soil and 2, 4-D reducenitrogen fixation by the bacteria that live on
the roots of bean plants reduces the growth and activity of nitrogen-fixing blue-green algae
and inhibits the transformation of ammonia into nitrates by soil bacteria. Mycorrhizal fungi
grow with the roots of many plants and aid in nutrient uptake. These fungi can also be
damaged by herbicides in the soil. One study found that oryzalin and trifluralin both inhibited
the growth of certain species of mycorrhizal fungi. Roundup has been shown to be toxic to
mycorrhizal fungi in laboratory studies, and some damaging effects were seen at
concentrations lower than those found in soil following typical applications.

32
Short-term and long-term action plan for possible solutions for the problems identified
and that could be recommended to the concerned authorities for implementation.

Increasing use of pesticides in fruits and vegetables can cause short-term adverse health
effects, called acute effects, as well as chronic adverse effects that can occur months or years
after exposure. Examples of acute health effects include stinging eyes, rashes, blisters,
blindness, nausea, dizziness and diarrhoea.

Short term action plan:

Reduce the use of chemical fertilizers

By applying a bio-fertilizer and manures can reduce chemical fertilizer and pesticide use.
Biological methods of pest control can also reduce the use of pesticides and thereby minimize
soil pollution.

Long term action plan:

Use organic farming:

Organic farming, agriculture system that uses ecological based pest controls and biological
fertilizers derived largely from animal and plant wastes and nitrogen-fixing cover crops.
Modern organic farming was developed as a response to the environmental harm caused by
the use of chemical pesticides and synthetic fertilizers in conventional farming, and it has
numerous ecological benefits.

33
Description of the Community awareness programme/s conducted w.r.t the
problems and their outcomes

Pest control
Organic pesticides are derived from naturally occurring sources. These include living
organisms such as bacteria, which is used to control caterpillar pests, or plant derivatives such
as pyrethrins. Mineral –based inorganic pesticides such as sulphur and copper are also
allowed. In addition to pesticides, organic pest control integrates biological, cultural, and
genetic controls to minimize pest damage. Biological control utilizes the natural enemies of
pests, such as predatory insects or parasitoids to attack insect pests. Pest cycles can be
disrupted with cultural controls, of which crop rotation is the most widely used. Finally,
traditional plant breeding has produced numerous crop varieties that are resistant to specific
pests. The use of such varieties and the planting of genetically diverse crops provide genetic
control against pests and many plant diseases.

Bio-control and natural pesticides

Bio-control makes use of pathogens (bacteria, fungi, viruses), insect predators or parasitoids,
pheromones and insects traps to keep pest low.
The total eradication of a pest, which results from these of synthetic would reduce the food
supply of the pest’s natural enemies, undermining a key element in system resilience. The
aim, therefore, should be to manage insect pest populations to the point where natural
operates in a balanced way and crop losses to pests are kept to an acceptable minimum.

Organic agriculture
Organic agriculture is a production system that sustains the health of soils, ecosystem and
people. It relies on ecological processes, biodiversity and cycles adapted to local conditions,
rather than the use of inputs with adverse effects. Organic standards strictly prohibit any use
of synthetic pesticides. Crop protection in organic agriculture builds on good agronomic
practices such as crop rotation and inter cropping, the use of organic manures, resistant
varieties and bio- control to prevent that pest, diseases and weeds cause significant damage.

34
Use of less hazardous pesticides
There are various systems to classify pesticides as per their toxicity for humans and the
environment. Phasing out the use of highly hazardous pesticides and replacing them with less
hazardous ones is therefore the most obvious way to reduce the negative side-effects of
pesticides.
This approach needs to be combined with safe handling of pesticides so that their impact on
people and the environment is minimized. The use of protective gear and the observation of
waiting periods before harvests are the most important measures in this regard.

Introduction
Pesticides are chemicals used to control any organism that might invade or damage crops,
food stores, or homes.
Because there are many kinds of potential pests, there are several kinds of pesticides. The
following are some examples

 Insecticides. These pesticides reduce destruction and contamination of growing and

harvested crops by insects and their eggs.

 Herbicides. Also known as weed killers, herbicides improve crop yields.

 Rodenticides. These are important for controlling destruction and contamination of crops
by vermin and rodent-borne diseases.

 Fungicides. This type of pesticide is especially important for protecting harvested crops
and seeds from fungal rot.

Insecticides

Insecticides are chemicals used to control insects by killing them or preventing them from
engaging in undesirable or destructive behaviors. They are classified based on their structure
and mode of action.

Insecticides are commonly used in agricultural, public health and industrial applications, as
well as household and commercial uses (e.g., control of roaches and termites). The most
commonly used insecticides are the organophosphates, pyrethroids and carbamates

36
Herbicides

Herbicides are chemicals used to manipulate or control undesirable vegetation. Herbicide

application occurs most frequently in row-crop farming, where they are applied before or
during planting to maximize crop productivity by minimizing other vegetation. They also may
be applied to crops in the fall, to improve harvesting.

Agriculture is the backbone of human society and it is essential for the survival of human
beings. Now a days, there are two main forms of agriculture that are widely practiced around
the world: conventional farming and organic farming. Before we rule out which method of
farming is better and deliberate over organic farming vs conventional farming let, us look into
both systems to have a better understanding.
Conventional farming
Conventional farming methods are focused on maximizing the yield of a crop. Conventional
farming makes use of fertilizers, pesticides to increase crop yield and crop quality is often
neglected.
Conventional farmers use chemicals to fight weeds and pesticides and also provide artificial
nutrients for crops. Conventional farming methods are not feasible as they take a huge toll on
the soil and environment
The chemicals used in conventional agriculture negatively impact the environment by causing
water pollution, soil erosion, increasing the emission of greenhouse gases- all which hamper
the quality of human health.

Characteristics of conventional farming

Conventional farming uses powerful chemicals to help manage crop fertility, pests and
diseases. Here are some of the characteristics of conventional farming:
 Use of chemical fertilizers
 Use of chemical pesticides
 Use of chemical weed killers
 Use of genetically modified organisms which can deliver consistent crops
 Production of only one or two crops in the same field per growing or year

38
 Characteristics of organic farming
Some of the essential characteristics of organic farming include:
 Use of biological fertilizers such as manure and compost.
 Implementation of sustainable farming methods such as crop rotation, mixed
farming.
 Organic agriculture does not use genetically modified (GM) seed, synthetic
pesticide or fertilizers.

The good news is that organic systems that emphasize soil health help farmers and ranchers
increase reliance to the impacts of climate change. There is also extensive research
demonstrating the potential of organic systems to reduce agriculture’s contribution to climate
change (i.e., mitigate climate change)
Organic systems do this by capturing and storing more carbon (CO2) in the soil.
While organic systems require some level of physical disturbance to control weeds, they
eliminate synthetic inputs and can significantly reduce tillage. Reduced tillage, crop
diversification, cover cropping, organic amendments, and sound nutrient management can
enhance carbon sequestration and build climate resiliency in organic agricultural systems.
39
They also release greenhouse gases.
Organic farmers do not use synthetic pesticides and fertilizers, one of the primary contributors
of greenhouse gases. Healthy soils help crops obtain nitrogen, phosphorus, and other nutrients
from organic soil organic matter. This reduces the need for fertilizers that can threaten water
quality and minimizes the release of greenhouse gases from soils.

 CHAPTER 6: RECOMMENDATIONS AND CONCLUSIONS OF THE
MINI PROJECT

Conventional farming methods are farming that are focused on maximizing the yield of a
crop. Conventional farming makes use of fertilizers, pesticides to increase crop yield and crop
quality is often neglected.
Conventional farmers use chemicals to fight weeds and pesticides and also provide artificial
nutrients for crops. Conventional farming methods are not feasible as they take a huge toll on
the soil and environment.
Organic farming is a system of farming that strives to produce nutritious and healthy food,
ensure that soil and environment stay healthy.
Organic farmers use biological fertilizer inputs and management practices such as cover
cropping and crop rotation to improve soil quality and build organic soil matter.
By increasing the amount of organic matter in the soil, organic farmers enhance the soil’s
ability to absorb water, reducing the impacts of drought and flooding. Improving soil organic
matter also helps it to absorb and store carbon and other nutrients need to grow healthy crops,
which, in turn, are better able to resist insect and diseases.
The benefits of organic farming outweigh those of conventional farming by a long shot.
Organic farming aims to improve the overall soil quality, produce nutritious crops, and pave
the way for a suitable means of agriculture, keeping the health of the environment and living
beings in mind. Organic farming in India still has a long way to go and farmers need to be
educated on the impact and consequences of conventional farming.
