The role of organic fertilizer

The role of organic fertilizers (1) improve soil, fertility. The main substance in organic fertilizer is organic matter, and the application of organic fertilizer increases the content of organic matter in the soil. Organic matter can improve the physical, chemical and biological properties of the soil, ripen the soil, and fertilize the soil. Welcome to the company **http://
(2) Increasing crop yield and improving the quality of agricultural products, amino acids and other substances, not containing nitrogen, phosphorus, potassium and other nutrients, but also containing a variety of sugars, amino acids and other substances, not only can provide nutrition for crops, but also promote soil microbial activities . Organic fertilizers also contain a variety of trace elements, such as livestock and poultry manure containing 2.2 to 2.4 grams of boron per 100 kilograms, zinc 2.9 to 29.0 grams, manganese 14.3 to 26.1 grams, molybdenum 0.3 to 0.4 grams, and effective iron 2.9 to 29.0 grams. Potassium dihydrogen phosphate The combination of organic fertilizer and chemical fertilizer has a significant effect on increasing yield, and can improve the quality of the product, reduce the content of nitrate and nitrite in vegetables, increase the content of vitamin C, and increase the sugar content in fruits and fruits.
Some organic fertilizers improve the soil, and the effect of fertility is greater, such as straw, peat, compost, etc.; some organic fertilizers are mainly used to supply nutrients for crops, such as human waste, chicken manure, etc. The difference is mainly determined by the ratio between organic matter and nitrogen content in different organic fertilizers. The organic matter structural substance is mainly carbon (C), so this ratio is called carbonitride (C/N), and the organic fertilizer with C/N greater than 30 is mainly used for soil modification, and the organic fertilizer with C/N less than 30 is used. Its role is to supply nutrients. The C/N of crop straw is about 100, and it is applied to the soil. The effect of improving the soil is very great. Because the amount of nitrogen contained is very small, not only can nitrogen be released during the decomposition and decay, but also nitrogen is absorbed from the soil. When there is a straw returning to the field, some chemical nitrogen fertilizer should be added to accelerate the decomposition process.
