Applying Amino Acids To The Soil

What is the real purpose of applying amino acids to the soil?
The purpose of applying amino acid fertilizers to the soil is not for crops to absorb and utilize them (crop roots generally do not directly absorb amino acids), but to maintain the fertilizer formula, prevent fertilizer antagonism, and improve fertilizer utilization.

Soil contains a large amount of humus, of which 80% is humic acid and 20% is amino acids. Soil only has soil function when it has humus, and it has the ability to chelate, complex, and adsorb nutrients, and the ability to provide crops with a reasonable diet. Applying humic acid and amino acids can enhance soil function.
Only a very small portion (4%-7%) of the amino acids we apply to the soil are absorbed by crops. In soils with sufficient nitrogen, crops will excrete large amounts of amino acids into the soil rather than absorb them. Only in cases of extreme nitrogen deficiency or low temperature will crops directly absorb small amounts of amino acids. The majority (93%-96%) is decomposed (eaten) by soil microorganisms. After the microorganisms die, they are returned to the soil in the form of ammonia nitrogen, which is then absorbed and utilized by crops.
