Plant Nutrition and BIO-Stimulation with natural L-amino-acids

All living beings require L-amino acids as the basic structural units for the formation of proteins, enzymes and as starting material for the synthesis of other essential substances. For plants, the normal and most practiced way of amino acid supply is indirect and makes use only of the root. Inorganic nitrogen fertilizers from soil application (ammonia, nitrate, urea …) are absorbed by the roots and transformed into L-amino acids by enzymatic processes. Besides favourable climatic and soil conditions, every plant needs energy for the transformation and synthesis of biological macromolecules. All these steps run naturally if the soil, water and plant physiologies are optimal.

Since the seventies, the alternative of directly supplying amino acids by foliar application has become more and more common. Compared to soil fertilization this method has no need of nutrient fertilizer dispensation in the soil and no need for biochemical transformation of inorganic nitrogen to organic amino acids. At early and essential stages of plant development, amino acids sprayed on the leaf are quickly up-taken by the leaf tissue and used as starting material for the synthesis of proteins, enzymes and sugar, improving significantly plant metabolism, development and growth.

Foliar application of amino acids is particularly helpful and widely practiced before and during stress situations when plant growth retardation or plant damage occurs. Stress conditions can include factors such as low temperatures, pest treatment weakening and soil fixation of conventional fertilizers.

The very extensive use of direct amino acid treatments in Mediterranean countries demonstrates the positive effect of amino acid spraying solutions for crop bio-stimulation and foliar nutrition. It represents a valuable alternative for the formation of biological macromolecules without having to go through the energy consuming intermediate steps of amino acid synthesis. Nevertheless, amino acid micro molecules should not be regarded as an alternative to soil fertilization. They are a successful and complementary support to conventional soil fertilizers with ready to use “endogenous” building blocks (amino acids) applied with an alternative method (through the leaf).

Product description

AMINOPOOL®LS is a water-soluble fertilizer and bio stimulant produced by hydrolysis of natural protein. The aminogram (the diagram of free and total amino acids) pictures a natural balanced amino acid composition and is proof of the absence of any synthesis free amino acids. AMINOPOOL®LS is rich in biological active L-amino acids and poor in sodium and chlorides.

We recommend a foliar application because of the small molecular size of amino acids contained in AMINOPOOL®LS. Free amino acids absorbed by the plant leaf and tissues are the starting material for the natural synthesis of a variety of essential proteins and sugar. A regular application of AMINOPOOL®LS during the period of greatest metabolic effort (transplantation, vegetative growth, flowering, ripening and maturation) supports a robust vegetative growth, improves the quantity of crop production and extends products’ shelf life.

Beyond the positive influence on vegetative plant development, amino acids also help preventing and correcting micronutrient deficiencies by improving the leaf and root absorption of microelements. AMINOPOOL®LS amino acids act as natural chelates and carriers through the plant tissues when applied in combination with microelement fertilizers. The chelating effect with certain amino acids such as glycine enables cation microelements like Iron, Calcium, Zinc, Manganese and Copper to link (ligate) with amino acids, form a metal complex and be more easily assimilated by the plant. The carrier properties of free amino acids and short chain peptides combined with the natural chelate properties of amino acids increase microelement fertilizers efficacy and help to reduce their application doses.

We particularly recommend AMINOPOOL®LS foliar application in typical plant stress situations. Just a few applications during extreme weather conditions, soil fertilizer fixation or damages from phytotoxicities, support recovery and contribute to a remarkable increase in plant robustness.

For much the same reason, AMINOPOOL®LS can be combined with the most used fungicides, herbicides, insecticides for an effective support of plant recovery during and after the treatment.

Directions for use

Dilute according to recommendations before using the product on plants. In case of inexperienced handling, we recommend a preliminary test on small areas before extending the treatment to the entire culture. The dosages advised are purely indicative and may vary depending on crop, crop vegetative cycle, climatic conditions and average yields expected.

  • In the greenhouse and when mixed with sulphur and trace elements apply the lowest recommended dose
  • With the exception of the olive grove where the product can be associated with copper and copper based fungicides avoid use in conjunction with copper, stannous, sulphur based products and mineral oils since the combination with free amino acids improves the absorption rate and can result in phytotoxicity

Handling and storage

Keep product in dry and cool conditions. Close properly the bag after use to avoid material caking. Read Safety Material Data Sheet and Technical Data Sheet carefully before use.
