The Efficacy, Characteristics and Application Methods of Compound Amino Acid Liquid Fertilizer

Compound amino acid liquid fertilizer is a water-soluble fertilizer that uses amino acids as its main nutrient, blended with medium and trace elements, humic acid and other components. Its raw materials mostly come from the enzymatic hydrolysis or hydrolysis products of animal and plant proteins; the nutrient molecules are small and highly water-soluble, so they can be absorbed and utilized relatively quickly by crop roots and leaves.

Compared with traditional solid fertilizers, this type of liquid fertilizer is flexible to use: it can be applied by flushing with irrigation water or by drip irrigation, and can also be diluted for foliar spraying. Amino acids have a certain chelating ability and can combine with elements such as calcium, magnesium, iron and zinc, reducing the fixation of nutrients in the soil and improving absorption and utilization efficiency, which helps to a certain extent in alleviating crop nutrient deficiency symptoms.

In application, compound amino acid liquid fertilizer is often used to promote root growth and strengthen seedlings at the seedling stage, to supplement nutrients during the flowering and fruit-setting stage, and for recovery and conditioning after stress such as low temperatures or pesticide damage. Reasonable use helps improve the quality and appearance of fruits, and it is fairly widely used in the production of vegetables, fruit trees and various cash crops.

When using it, attention should be paid to concentration control. Foliar spraying must be diluted according to the product instructions, and the high-temperature periods of the day should be avoided to prevent leaf scorching. Compared with amino acid organic fertilizer, liquid fertilizer focuses more on rapid nutrient supplementation, while organic fertilizer focuses on improving the soil and building soil fertility; using the two together gives better results. In addition, the product should be stored in a cool place, away from direct sunlight and freezing, and should be used up as soon as possible after opening.
