Foliar fertilization of crops is also called extra-root fertilization (follow-up) fertilizer, that is, supplementing the nutrients required by plants through foliar spraying, which plays a role in regulating plant growth, supplementing the missing elements, preventing premature aging and increasing yield. Especially under adverse conditions, the root absorption function is hindered, and foliar fertilization often exerts a special effect, which can supply nutrients directly and quickly, avoid nutrients being adsorbed and fixed by the soil, and improve fertilizer utilization.

Inorganic nutrient foliar fertilizers. These foliar fertilizers have high levels of nutrients such as nitrogen, phosphorus, potassium and trace elements. Their main function is to provide various nutrients for the crops and improve the nutritional status of the crops, especially suitable for later crop growth. Various nutritional supplements. Its characteristics are: fast absorption speed, but more residues in the plant.
Regulated foliar fertilizer This type of foliar fertilizer contains substances that regulate the growth of plants, such as auxin, hormones and other components. Its main function is to regulate the growth and development of crops. It is suitable for early and middle plant growth. Its characteristics are: fast absorption speed and less residual harmful substances.
Biological foliar fertilizer This type of foliar fertilizer uses the organic substances extracted from soybean meal and farm fertilizer as a carrier to add active microorganisms. Such fertilizers contain microorganisms and metabolites, such as amino acids, nucleotides, and nucleic acids. The main function is to stimulate crop growth, etc., promote crop metabolism, reduce and prevent the occurrence of pests and diseases. Its characteristics are: obvious fertilizer effect, basically no residue, mostly green fertilizer, but slow absorption rate, harsh spraying conditions and poor stability.
Compound foliar fertilizers There are many kinds of foliar fertilizers, and the compounding forms are various. It has many functions, which can provide nutrition and stimulate growth and development.
Humic acid foliar fertilizer This kind of foliar fertilizer has a long effective period, increases the ground temperature of the protected ground, and effectively reduces the occurrence of common physiological and pathological diseases of low temperature and high humidity. Humic acid can be divided into yellow humic acid, brown humic acid and black humic acid according to its dissolution and color in water. Black humic acid is basically insoluble in water, brown humic acid is slightly soluble in water, yellow humic acid has a small molecular weight, is easily soluble in water, and can chelate mineral elements. Its characteristics are: fast effect, green, and pollution-free.
The amino acid foliar fertilizer is mainly based on amino acids and complexes with micro-fertilizers, containing plant nutrient growth regulators and essential trace elements of plants. Amino acid foliar fertilizer can promote root growth, strengthen seedlings, strengthen plants, enhance leaf photosynthetic functions and crops' resistance to stress, diseases and insect pests, and have a significant yield increase effect on a variety of crops. Its characteristics are: amino acid fertilizers are non-toxic, pollution-free, and do not pollute the environment.
