 About water-soluble fertilizer you should know the knowledge

What is water-soluble fertilizer?

    Water-soluble fertilizer refers to the large amount of elements completely and quickly dissolved in water single water-soluble fertilizer (such as urea, potassium chloride, etc.), water-soluble compound fertilizer (MAP, DAP, potassium nitrate, MKP, etc.), water-soluble fertilizers specified in the industry standards of the Ministry of Agriculture (large amount of water-soluble fertilizers, water-soluble fertilizers of intermediate amount of elements, water-soluble fertilizers of microelements, water-soluble fertilizers of amino acids, water-soluble fertilizers of humic acid) and organic water-soluble fertilizers etc.
    Water-soluble fertilizers can be summarized as a complete, rapidly dissolved in water, a single fertilizer, multi-compound fertilizers or functional organic water-soluble solid or liquid fertilizers, with easy to be absorbed by the crop, can be used for irrigation fertilizer, foliar fertilizer, soilless cultivation, soaking seeds dipped in roots and other characteristics.

The types of water-soluble fertilizer

    Water-soluble fertilizer can be divided into: water-soluble fertilizer with large amount of elements, water-soluble fertilizer with medium amount of elements, water-soluble fertilizer with amino acids, water-soluble fertilizer with microelements, water-soluble fertilizer with humic acid, organic water-soluble fertilizer and so on according to the different nutrient elements it contains. In the actual application process, a variety of water-soluble fertilizers are formulated to form a full nutritional composite water-soluble fertilizers, combined with water-fertilizer integration project can fully meet the needs of crop growth and production.

Large element water-soluble fertilizer

    Liquid or solid water-soluble fertilizers are mainly made of nitrogen, phosphorus, potassium and large amount of elements, and in accordance with the proportion needed for plant growth, add copper, iron, manganese, zinc, boron, molybdenum microelements or calcium, magnesium and medium amount of elements.  The content of large elements in solid products is ≥50%, and the content of trace elements is ≥0.2~3.0%; the content of large elements in liquid products is ≥500g/L, and the content of trace elements is ≥2~30g/L.

Medium element water-soluble fertilizer

    Liquid or solid water-soluble fertilizers made of calcium, magnesium and trace elements according to the proportion needed for plant growth, or with the addition of appropriate amount of copper, iron, manganese, zinc, boron and molybdenum. 

Trace element water-soluble fertilizer

    Copper, iron, manganese, zinc, boron, molybdenum trace elements in accordance with the proportion of suitable for plant growth required for liquid or solid water-soluble fertilizers. 

Amino acid-containing water-soluble fertilizer

    Free amino acids as the main body, according to the proportion required for plant growth, adding copper, iron, manganese, zinc, boron, molybdenum trace elements or calcium, magnesium and medium elements made of liquid or solid water-soluble fertilizers, the product is divided into two types of trace elements and calcium elements. The free amino acid content of trace element-type amino acid-containing water-soluble fertilizers is not less than 10% and 100g/L for solid products and liquid products respectively; and the total content of at least two kinds of trace elements is not less than 2.0% and 20g/L. Calcium-element-type amino acid-containing water-soluble fertilizers are also available in two kinds of solid products and liquid products, and the indexes are the same as that of trace element-type products, except that the content of calcium element is not less than 3.0% and 20g/L for solid products and liquid products respectively. All the indexes are the same as those of trace element type, except that the calcium content of solid products and liquid products is not less than 3.0% and 30g/L respectively.

Water-soluble fertilizer with humic acid

    Water-soluble fertilizer with humic acid is a kind of water-soluble fertilizer containing humic acid. It is a liquid or solid water-soluble fertilizer made of humic acid in the proportion required for plant growth, with the addition of appropriate amount of nitrogen, phosphorus, potassium massive elements or copper, iron, manganese, zinc, boron, molybdenum trace elements. Humic acid is a kind of natural macromolecule organic matter formed by microbial decomposition and geochemical process of organic matter such as plant and animal residues, mostly extracted from peat, lignite and weathered coal, which can stimulate plant growth, change soil and fertilize the soil, and improve the effectiveness of nutrients and crop resilience. The content of humic acid in solid products of massive element type is not less than 3%, and the content of massive element is not less than 20%; the content of humic acid in liquid products of massive element type is not less than 30g/L, and the content of massive element is not less than 200g/L; the content of humic acid in solid products of trace element type containing humic acid is not less than 3%, and the content of trace element is not less than 6%.

Other water-soluble fertilizers

    Not within the scope of the above five water-soluble fertilizers, the implementation of enterprise standards for other water-soluble fertilizers with fertilizer efficacy. Generally organic water-soluble fertilizers are more, including: alginate, chitin, chitosan and other extracts as the core raw materials of fertilizer varieties.
