The role of sodium humate in aquaculture

First, the basic understanding of sodium humate a, product English name Sodium humate, product alias: sodium humate; humate sodium salt (Humin sodium salt); humic acid sodium salt;

How is sodium humate produced? In China, agriculture is used as an organic ecological fertilizer. It is based on weathered low-efficiency lignite, whitened low-calorie peat and smoky brown coal. After special pulverization, it is passed through biological fermentation technology. The process is followed by a macromolecular organic weak sodium salt having a plurality of functions prepared by high temperature polymerization. Its structure is relatively complicated.

It is known that humic acid molecules contain benzene rings, fused rings and some heterocyclic rings (such as pyrrole, furan, anthracene, etc.), and each aromatic ring has a bridge bond and various functions on the aromatic ring. The group is mainly a carboxyl group, a phenol group, a hydroxyl group, a methoxy group, a thiol group or the like. The content of humic acid dry base in sodium humate is more than 75%, which was originally produced as a farm animal companion. It is used as a feed additive.

Third, the physical properties and chemical composition of sodium humate 1, appearance: black bright color, amorphous solid particles 2, particle size: 20—120 mesh 3, water-soluble humic acid content (dry basis) ≥ 70% 4, Water insoluble matter (dry basis) ≤12%5, moisture content ≤15%6, Fe content ≤0.45%7, PH value 8.0-9.0

Fourth, the identification of sodium humate high quality (HA-Na) is black and black bright, light, the sun shines under the beautiful luster of irregular irregular particles. It is non-toxic, odorless, non-corrosive, extremely watery, and free of any deposits. The highest quality products are made of high quality low calcium and low magnesium weathered lignite containing natural humic acid. Th=uminous coal is chemically refined.

It is a multifunctional polymer compound containing more active groups such as hydroxyl, sulfhydryl and carboxyl groups. It has a large internal surface area and strong adsorption, exchange, complexation and chelation ability. China’s largest production base of sodium humate is in Baotou. As a synergist in aquaculture, the fertilizer and shading properties of sodium humate are widely used. Both have achieved significant economic benefits….
