To explain the amino acid fertilizer effect, firstly we should know what the amino acid fertilizer is and where the amino acid is from.
What is amino acid fertilizer?
Amino acid is the basic unit of protein, and it is a kind of biologically active macromolecule needed by living body. Life activities are closely related to it. Amino acids are the main organic nitrogen compounds in the soil, accounting for 15% to 60% of total soil nitrogen. Amino acids in soil mainly come from microorganisms, animals, plants and their metabolites.
Amino acids are an important component of soil organic nitrogen and an important nutrient source for soil microorganisms. Soil microorganisms can use amino acids as precursors in the metabolic process, and then synthesize plant growth regulators through biological pathways to stimulate plant growth and regulate plant physiology process.
Amino acid fertilizer can be divided into two categories: plant source amino acid and animal source amino acid. Different sources of amino acid fertilizer have different effects on crops due to their different amino acid composition ratios. If you need to improve the stress resistance of crops, amino acids derived from animal skin and bones with higher proline and glycine are a good choice.
If you want to increase the lignification of plants, control shoots, and increase anthocyanins, amino acids derived from animal blood with higher phenylalanine are the better choices. If it is to promote the growth of green leaves, the effect of plant-based amino acid raw materials such as wheat and corn with higher glutamic acid is more significant. Therefore, plant source amino acid and animal source amino acid are not good or bad. Only by focusing on their characteristics can they function well.
Amino acid fertilizer effect: improve the soil.
Amino acids can promote the formation of soil aggregates: soil aggregates are the basic unit of soil structure. Amino acids can change the physical and chemical properties of soil that are too salty, too alkaline, highly dispersed soil particles, and poor soil structure, and promote the formation of soil aggregates.
After the application of amino acids, the soil bulk density decreases, and the total soil porosity and water holding capacity increase accordingly, which helps improve the soil’s ability to retain water and fertilizer, thereby creating good conditions for the growth and development of plant roots.
Effect on soil microbial flora and enzyme activity.
Soil microorganisms are one of the important reasons for the composition of the soil.
It has an important influence on the transformation of soil organic and inorganic matter, the cycle of nutrient elements, and the formation of enzymes, which are essential biologically active substances in the process of plant life activities. Amino acids can promote the activity of soil microorganisms, increase the number of soil microorganisms, and enhance the activity of soil enzymes.
A large number of studies have confirmed that amino acids are promoters and catalysts for the synthesis of various enzymes in plants, and play an important role in plant metabolism. The application of amino acids can increase the number of aerobic bacteria, actinomycetes, and cellulolytic bacteria. It is beneficial to accelerate the mineralization of organic matter and promote the release of nutrients.
