How to make real amino acid fertilizer?
The relative molecular weight of free amino acid is the smallest. It’s also the kind required by amino acids water-soluble fertilizer registered by Chinese Ministry of Agriculture.
In theory, it would be considered that the smaller the molecular weight, the easier it is to be absorbed. But it may not be exactly like that. More than a dozen different free amino acids will compete and antagonize each other in the process of being absorbed by plants. Just as the sixteen nutrients we know, promote each other, compete and antagonize each other.
Although the polypeptide, oligopeptide and amino acid are gradually decomposed from the protein, the oligopeptide has the unique physiological function (growth regulation, disease resistance, etc.), which the amino acid does not possess. It is more easily absorbed by the plant, and does not consume the energy of itself.
The oligopeptide, the polypeptide are also an endogenous hormone of plant, which plays an important role in the development of the plant. The action mechanism of the polypeptide hormone is very complex. Only the oligopeptide can have thousands of different combinations.
A highly functional amino acid bio stimulant is not only the amino acid and the oligopeptide, the polypeptide. Many foreign enterprises will add some biologically active substances which can increase the function. Such as the derivatives of the amino acids, the vitamin series,the plant extracts, seaweed, etc..All of these could take full advantage of the functionality of these active substances.
