Corn steep liquor powder is a kind of organic fertilizer rich in organic matter, which can provide nutrition for crop growth, fertilize and improve soil. Its functions are as follows:

1）Provide the nutrition that crops need. Organic fertilizer is rich in nutrients for crop growth, and energy continues to provide food for crops. Providing nutrients is the basic feature of organic fertilizers and their main function.

2）Improve soil structure, improve soil fertility. Improve the content of soil organic matter, update the composition of soil humus, make the soil fertile. The organic fertilizer applied to the soil is decomposed into single compound under the action of microorganism, and then recombined into new, more complex and relatively stable soil specific polymer organic compound through biochemical action. Humus. Humus is a stable organic matter in soil, which plays an important role in soil fertility.

3）Improve soil biological activity and stimulate crop growth. Organic fertilizer is the main source of microbial energy and nutrition. The application of organic fertilizer is conducive to soil microbial activities and promote crop growth and development. Microbial metabolites not only contain inorganic nutrients such as nitrogen, phosphorus, potassium, but also contain various amino acids, microorganisms, hormones and other substances, which have a great impact on the growth and development of plants.

4）Improve interpretation and purify soil environment. Organic fertilizer can increase the substitution of soil cations, increase the adsorption of most heavy metals, effectively reduce the toxicity of heavy metal ions to crops and prevent them from entering plants.
