LIQUID MIXTURE OF CALCIUM AND MAGNESIUM
Fertigation

Guaranteed analysis 7.2% Water-soluble Calcium Oxide (CaO)

(% weight/weight) 0.3% Water-soluble Magnesium Oxide (MgO

Formulation type Soluble liquid concentrate

Accumulation of excess soluble salts in the root zone leads to a loss in soil
productivity in terms of crop yields. This phenomenon is of major concern
worldwide. This product provides a solution to excess salinity-sodicity. 5

Soils can be saline due to geological processes or they can be man-made.

There is no critical point of salinity where plants fail to grow. As salinity
increases, growth decreases until plants become chlorotic and die.
To improve crop growth in such soils, excess salts must be removed from
the root zone. The use of an appropriate amendment will accelerate this
process to a greater or a lesser extent depending on the soil infiltration
and drainage characteristics and the electrolyte level of the irrigation water.

PROMI-SAL® was the first product developed by the company to address

issues related to saline or saline-sodic soils. It contains organic acids that
sequester those cations that interfere with plant development, such as
sodium, and release calcium, an essential nutrient.

For 30 years, this has been a successful product for all types of crops,
especially in areas with mediterranean, semi-arid or arid climates, where
salts tend to accumulate naturally or through agricultural overexploitation.

Guaranteed analysis 10.2% Water-soluble Calcium Oxide (CaO)

(% weight/weight) 0.3% Water-soluble Magnesium Oxide (MgO)

Formulation type Soluble liquid concentrate

An smart evolution of PROMI-SAL®.

It is an even richer product in organic acids and calcium. These organic

acids contain a large amount of carboxyl groups, that act as carriers for
those interchangeable calcium ions. When those soluble organic acids
reach the soil, they exert their action replacing calcium by sodium in the
soil colloid.

Additionally, PROMI-SAL® EXTRA promotes soil flocculation, counteracting

the dispersive effect of sodium ions. This property can be explained by
the high electrical polarity of organic acids: negative charges in the surface
of the clay particles are attracted towards the positive poles of the acids,
creating stable aggregates. Between those aggregates, roots, air and
water can penetrate easily, giving the soil a suitable structure for high yield
agricultural production.

The dose of the product must be obtained on the basis of a soil analysis.
Where these are not available, the dose is decided according to the
following diagnostic criterion: water infiltration problems, cracked soil
when dry, reduced germination or vigour and presence of salty patches.

9% Humic Acids
(% weight/weight)
7% Fulvic Acids

Formulation type Soluble liquid concentrate

HUMUSLIGHT® LEONARDITE is an amendment that increases the

concentration of organic matter in the soil due to the contribution of humic
6 and fulvic acids. It improves its structure, cation exchange capacity, nutrient
availability, root growth and the proliferation and activity of beneficial
microorganisms.

Chemically, humic substances consist of plant material resistant to further

decomposition, of substances undergoing decomposition, of complexes
resulting from decomposition (either by hydrolysis or by oxidation and
reduction) and of various compounds synthesized by microorganisms.

With regard to water, when applied to clay soils, humic acids can help in
reducing compaction allowing for enhanced water penetration and better
root zone growth and development. When applied to sandy soils, humic
acids add essential organic material necessary for water retention.

Formulation type Soluble liquid concentrate

With 30% of total humic extract, this product constitutes a concentrate of

organic matter, especially suitable for soils depleted of nutrients, or for
those soils submitted to intensive agriculture or for those cases in which
particularly demanding crops in organic matter are planted.

All the acids present in this formulation are weak aliphatic and aromatic
acids, rich in carboxyl and hydroxyl groups which make them highly
reactive. They have a low molecular weight wich range from 1000Da to
10000Da and so, can be classified as Fulvic Acids. They can easily be
absorbed by plant roots, stems, and leaves carrying trace minerals and
other nutrients with them. They are excellent additions for both in-row and
foliar applications, as fulvic acids are the most effective carbon containing
chelating compounds known.

This formulation provides magnesium and iron along with these fulvic acids
and thus, in addition to working as a soil improver, it works as a chlorosis
prevention treatment and as a photosynthesis booster. Fulvic acid also
stimulates root growth so plants can increase both water and nutrient
uptake.

Guaranteed analysis 30% Organic matter

(% weight/weight) 16% Organic carbon

Formulation type Soluble liquid concentrate

This formulation contains a high concentration of fulvic acids and the

highest amount of organic carbon in this product range. It is particularly
suitable for soils poor in organic matter, e.g. sandy soils. 7

Organic carbon is vital to soil capacity to provide edaphic ecosystem

services. The condition of this capacity is termed soil health, a term that
communicates the value of understanding soil as a living system as
opposed to an abiotic component.

Total organic carbon influences many soil characteristics including colour,

nutrient holding capacity (cation and anion exchange capacity), nutrient
turnover and stability, and also microbial activity, as organic carbon is a
food source for microorganisms. All this parameters in turn influence water
relations, aeration and workability.

The organic carbon content of a soil can be measured and is a valuable

indication of the potential humic-chemistry of a soil.

AZUFLOW®
ACIDIC SOLUTION OF NITROGEN AND SULFUR
Fertigation

Guaranteed analysis 15% Ureic Nitrogen (N)

(% weight/weight) 40% Water-soluble sulfur (SO3)

Formulation type Soluble liquid concentrate

It is used in all types of crops by means of localized irrigation to amend

limestone and/or alkaline soils. It reduces its content in salts and improves
the structure of the soil, in addition to solubilizing nutrients.

Sulfur is an essential nutrient for plant growth. Oil crops, legumes, forages
and some vegetable crops require sulfur in considerable amounts. In many
crops, its amount in the plant is similar to phosphorus.

Some major roles of Sulfur are:

- It is found in some amino acids, the building blocks of proteins. Most of the
sulfur absorbed by plants, about 90%, is used for that purpose.
- Essential for chlorophyll formation. It is a major constituent of one of the
enzymes required for the formation of the chlorophyll molecule.
- Essential in the synthesis of oils (oil crops).
- Active in the metabolism of nitrogen.

molybdenum. Additionally, rising the soil pH prevents toxicity from high
concentrations of iron, aluminium, copper, zinc, manganese or cobalt.

PROMI-ACID® contains organic acids. Their negative charge confer them

great affinity for dissolved cations, giving great nutrient complexing
properties to the product.

Due to the different water and soil compositions, dosage may vary greatly

Guaranteed analysis 20% Ureic Nitrogen (N)

(% weight/weight) 2% Water-soluble Boron (B)

Formulation type Liquid soluble concentrate

It is particularly efficient as a foliar spray, as all of the nitrogen is in ureic

Promi – Fertil® Nitron Plus – Boron is advised to be used in high nutrient-
demanding periods, for example, at initial development stages to ensure
a proper flowering, setting and fruit or grain growth season. It is suitable
for crops that exhibit more sensitivity to boron deficiencies like alfalfa, fruit
trees, olive trees, vine, cauliflower, sugar beet, rapeseed, sunflower, carrot
and tomato.

Boron supply not only enhances yield, but improves the quality of forage
harvested, as boron deficient leaves dry much faster than the stems and are
often lost in raking or baling. This leaf loss causes protein levels in the
forage to drop significantly.

Formulation type Liquid soluble concentrate

It is recommended as a highly efficient supply of potassium during crop’s

biggest demand stages. Usually, potassium is critical during ripening
processes. Contains EDTA as a stabiliser.

Most of the positive effects attributed to potassium regarding fruit earliness

and visual and organoleptic quality (size, colour…) are in fact, shared with
phosphorus. Both enhance ripening processes and counterbalance any
negative issue derived from too much nitrogen fertilisation. The most
advisable stages for its application are flowering, fruit setting and ripening.

Potassium is known to take part in the following plant metabolic processes:

- Regulation of cell pH (acid-base balance)
- Osmolarity
- Maintenance of turgidity
- Stomata opening and closure
- Tolerance to drought and salinity
- Transpiration

Guaranteed analysis 17% Water-soluble Calcium Oxide (CaO)

(% weight/weight) 0.5% Water-soluble Zinc (Zn)

Formulation type Liquid soluble concentrate

This is a liquid corrector of calcium deficiencies, complemented with zinc,

whose deficiency is common in many agricultural soils.
14
Some of the main functions of calcium are its role as secondary cellular
signaling ion, as a component of cell wall, as a structural stabiliser of cell
membranes and finally it is a component of calmodulin, an activator protein
of many enzymes.

Zinc has many important functions in plants, such as its role as cofactor of
many enzymes, as a structural stabiliser of proteins and cell membranes,
and also plays its role as component of DNA histones.

Promi-Cal® Extra is especially recommended for the most sensitive crops

to calcium deficiencies, such as tomato and apple.

It may be used in any crop when conditions concur that may cause a
deficiency in calcium, such as excessive phosphate fertilisation, low soil
pH, high air humidity, low light intensity, low temperatures and drought.

boron at the right ratio for most crops.

Some of the main effects produced by calcium deficiencies in crops are

higher susceptibility to environmental stress, diseases and pests; lower
plant development, lower root growth, root anomalies, chlorosis in leaves,
lower activity of leaves buds, lower quality of fruits and fruit physiopathies.

This product has two main advantages over other calcium-based fertilisers:
Calcium formate is quickly absorbed by plants and formate ion is a known
bacteriostatic agent.

We recommmend to make joint applications of this product along with an

Iron is poorly available for crops especially in intensely washed sandy soils,
soils with high pH (pH>7), calcareous soils (with more than 15% calcium
carbonate), soils where calcareous amendments have recently been applied
and in soils with salinity problems.

To overcome deficiencies, chelated forms of iron are the choice of

preference. Orto-orto configuration is the most stable in soils where pH
is neutral or alkaline. The highest the orto-orto percentage, the better in
limestone soils.

EDDHA is far superior in calcareous soils to other chelating agents derived

biostimulants based on amino acids and seaweed.

Plants accumulate several amino acids in diverse tissues

in situations of abiotic stress; they have several functions:
osmoregulation, ion transport, stomata opening, and
detoxification of heavy metals. In addition, they can modulate
the synthesis of some enzymes and gene expression.

22 Seaweed contain many molecules that can help plants

overcome abiotic stress scenarios: alginic acid (improves soil
structure), mannitol (antioxidant), hormone-like compounds,
peptides, micronutrients and many other substances like
phenols, terpenoids, etc.

In addition to the very specific products on the previous page

and with the aim of offering differentiated products that can be
applied in as many situations as possible, the following ranges

or as a productivity booster.

Brown algae are rich in active ingredients such as polysaccharides (laminarin,

alginates and fucanes), sugar alcohols, proteins, lipids, polyphenols, and
hormone-like compounds. All of them have positive effects on the plant’s
phisiology, wether they act as growth promoters, as antioxidants or as soil
improvers.

The high concentration of free amino acids ensures a stimulation of all vital
processes, since the presence of 18 different amino acids can affect virtually
any metabolic pathway. Likewise, they also provide rapid recovery from
occasional episodes of hydric or thermal stress such as droughts, frosts,
and even make it easier to cope with excessive concentrations of metals in
soils or with an excessive amount of salts.

24 This product is one of the company’s most veterans, and it is precisely

resisting the passage of time that guarantees its effectiveness as a
biostimulant. It should be used in stages of increased growth or metabolic
activity.

The union of amino acids with iron allows to stimulate all the essential
metabolic processes of the plant at the same time that it impels the
photosynthesis.

Iron deficiency manifests itself as an easily recognizable interveinal

chlorosis. Iron is a constituent of several enzymes and some pigments, and
assists in nitrate and sulfate reduction and energy production within the
plant. Additionally, it is essential for photosynthesis, as one of the main
protein structures involved, Photosystem II contains iron at its core which
allows for the transfer of electrons.

This product is an evolution of the one at the top of this page and its form
of use is exactly the same.

To further promote photosynthesis, magnesium has been added. Many

enzymes in plant cells require magnesium in order to perform properly.
However, the most important role of magnesium is as the central atom in
the chlorophyll molecule. Chlorophyll is the pigment that gives plants their
green color and carries out the process of photosynthesis. It also aids in
the activation of many plant enzymes needed for growth and contributes
to protein synthesis.

Finally, molybdenum has been added. It is the only nutrient whose

availability is optimal at strongly alkaline pHs and therefore, it is important
to prevent its deficiency. Its role in plant metabolism is closely linked to
nitrogen, as it forms part of the enzymes that catalyse nitrate into nitrite,
and the latter into ammonia. It also allows to join phosphorus of inorganic
origin to organic compounds.

It has an equally balanced aminogram, great compatibility with any fertiliser

and works synergically with many plant growth regulators and plant
protection products, as many amino acids act as carriers for those active
principles.

The main functions of amino acids in plants are: protein synthesis,

resistance to abiotic stress, promotion of photosynthesis, regulation of
stomata activity, nutrient complexing, improvement of pollination rate and
proper fruit development.

It should be noted that soil application of amino acids boosts indeed

microbial activity. The equilibrium of the microbial flora in agricultural soil
is a basic question for a good mineralisation of the organic matter and also
for a good soil structure and fertility around the roots.

With a concentration of 80% of free amino acids, this product presents in

It is marketed as a soluble powder, and can be used as part of a program

throughout the crop cycle at very low doses.

It is compatible with all commonly used fertilisers and can therefore be

added to any treatment and save on the number of field applications. Its
synergistic effect with phytosanitary products guarantees the efficacy of
this product.

The logic in the use of amino acids is as follows: if your plant can utilize
supplementary amino acids without having to create them itself out of
oxygen, carbon, nitrogen, hydrogen and sometimes sulfur, your plant has
much more available energy to use where it deems necessary. This helps it
maintain not only vigorous growth but pest and disease resistance as well.

It is thought that some amino acids can only be absorbed through the
stomata, and so, combining foliar and root applications may be the best
practice.

used plant protection product.

It must be stated that microbial life and even physical soil components
themselves will be taking advantage of amino acids. Keep in mind that
amino acids contain high amounts of nitrogen within their structure and
due to the high solubility of amino acids they are to some degree a nitrogen
fertiliser themselves. Adjusting the fertiliser program slightly may be
necessary to compensate for this.

PHOSPHONATES
Fertigation and foliar spray
Phosphonates describe the salts and esters of phosphorous acid.

These molecules are known to elicit natural defences of plants, via

the synthesis and accumulation of fungus-inhibiting chemicals called
phytoalexins. These include many different chemical types, like terpenoids,
alkaloids or isoflavonoids; many of them have modifications in their
structure that make them unique to every plant species.

It is very critical not to use excessive amounts of phosphonates, as high 29

concentrations do not activate enzymes responsible for phytoalexin
synthesis. Low doses, particularly in the root zone, are most effective.

BIOESTIM® products are different combinations of phosphonates and

nutrients, designed to fit any lack of any nutrient while providing a
promoter of defences against fungal infections.

Please seek agronomic technical advice before using this product, and check
local regulations for any possible limitations on the use of phosphonates in
your region.

These products are designed for export, not for use in the EU.

which hinders the growth of fungi.

Silicon seems to benefit certain plants

found to improve drought tolerance
and delay wilting in certain crops where
irrigation is withheld and may enhance
the plant’s ability to resist micronutrient

MUCIGEL® is based on the seaweed Ascophyllum nodosum extracts rich in

34 proteins, polysaccharides, and naturally ocurring hormones or substances
with hormone-like activity at the right ratio.

It promotes the development and the formation of new roots, increases

the density of thin root hairs, and the number of lateral roots. In addition,
it promotes the secretion of mucilaginous substances that improve root
protection and nutrient absorption. So, MUCIGEL® is intended to be used
during all the crop cycle, but with particular emphasis from transplantation
or germination until flowering.

MUCIGEL® can also help against endoparasitic nematodes, reducing the

number of nodules and nematode eggs.

Formulation type Liquid soluble concentrate

This product has the same composition of Bio-Mucigel®, but provides

Cobalt and Molybdenum, for better performance in leguminous crops.

Molybdenum is an essential component in two enzymes that convert nitrate

into nitrite (a toxic form of nitrogen) and then into ammonia before it is
used to synthesize amino acids within the plant. It also needed by symbiotic
nitrogen fixing bacteria in legumes to fix atmospheric nitrogen. Plants also
use molybdenum to convert inorganic phosphorus into organic forms in
the plant.

It is a component of a number of enzymes and increases the drought

resistance of seeds. In legumes, cobalt is important for nitrogen fixation by
the bacteria that associate with legumes. It is also a component of vitamin
B12 and so, it is important for human consumption.

BIO-CYTOLAN® ALGAS
SEAWEED EXTRACT
Fertigation and foliar spray

Guaranteed analysis 1.5% Alginic Acid

(% weight/weight) 0.5% Mannitol

Formulation type Liquid solution

BIO-CYTOLAN® ALGAS is a liquid formula based on Ascophyllum nodosum

seaweed extracts, which contain naturally occurring phytohormones, such
as cytokinins and auxins, in addition to other biostimulants, such as betaine
36
and various oligosaccharides, which can increase the resistance and
tolerance of plants to various pests and diseases.

Alginic acid, present in the cell wall of algae acts as a hydrocolloid, retaining
soil moisture and nutrients and therefore improving soil structure and
preventing the loss of materials through leaching or runoff.

Mannitol, is a sugar alcohol with osmoprotective activity, and therefore

gives protection to the plant against saline or hydric stress. At the same
time, it has antioxidant properties, protecting the cells against reactive
oxygen species (ROS) generated in stress situations.

Formulation type Liquid solution

BIO-CYTOLAN POLVO is an extract of algae of the Ascophyllum nodosum

species that contains natural elements that stimulate the plant in its
physiological processes.

Its application boosts plant metabolism and increases the photosynthetic

capacity; this will allow to overcome stresses caused by high temperatures
or frosts, by an excess or the lack of water.

Its high percentage of organic matter and natural metabolites make BIO-
CYTOLAN® POLVO a great activator of soil microbiota that also favors the
development of the root system.
