Agriculture is the foundation of the national economy, and soil and fertilizer are the foundation of agriculture. The leading agriculture in the 21st century is ecological agriculture, and the leading food in the 21st century is green food.

  Agriculture is the foundation of the national economy, and soil and fertilizer are the foundation of agriculture. The leading agriculture in the 21st century is ecological agriculture, and the leading food in the 21st century is green food. Green food is a safe, high-quality and nutritious food without pollution. Therefore, green food has strict restrictions on the growing soil, chemical fertilizers and pesticides. This requires the development of high-efficiency and pollution-free high-quality green fertilizer to meet the growing demand for high-efficiency agriculture. Amino acid multi-element fertilizer is a high-quality green fertilizer that meets this requirement and has high-quality plant physiological function. Let's talk about the production of amino acid fertilizer and its effect on soil:

  1. Production of amino acid multi-element fertilizer

  At the end of the 20th century, in order to meet the requirements of organic food, the research of amino acid multi-element fertilizer came into being. Amino acid multi-element fertilizer is a high-efficiency, pollution-free and high-quality green fertilizer with the advantages of amino acid fertilizer and trace element fertilizer. The core steps of its production process: ① protein hydrolysis to amino acids; ② Amino acids chelate with trace elements. The performance and cost of amino acid as chelating agent are the key to the wide application of amino acid multi-element fertilizer. Amino acid multi-element fertilizer mainly uses waste protein hydrolysis to prepare compound amino acid multi-element fertilizer, such as using the waste liquid after hair hydrolysis to extract cystine, or using animal hair to extract amino acids. The methods of protein hydrolysis to produce amino acids include acid hydrolysis, alkali hydrolysis, enzyme hydrolysis and high temperature and high pressure hydrolysis, among which acid hydrolysis is the most widely used. As an amino acid for fertilizer, the main goal of technological research is to reduce the cost. At present, attention is paid to the extraction of amino acids from protein waste liquid. The waste liquid contains 17 ~ 18 kinds of amino acids, and the content is very high; Using waste liquid to develop amino acid fertilizer can not only reuse waste, but also reduce environmental pollution. The methods of extracting amino acids from waste liquid and developing amino acid fertilizer mainly include membrane separation method, electrochemical method and ion exchange method.

  2. Effect of amino acid multi-element fertilizer on Soil

  Amino acids are the precursors of protein synthesis, and proteins are the most abundant and complex biological macromolecules in living cells. They are everywhere in the biological world. Although the demand of medium and trace elements is very small, they play the role of coordination, dependence and restriction among elements. Most of them are components of enzymes or coenzymes and are very active in plants. Without them, crops can not develop normally, and serious physiological diseases and even death will occur. Therefore, amino acid multi-element fertilizer and its degradation products will not pollute soil and environment.
