Fertilizer factories in industry convert crop straw, livestock and poultry manure and other organic wastes into bio-organic fertilizers through beneficial microorganisms, making them harmless and resource-based, solving the worries of planting and breeding industry, and increasing the added value of livestock and poultry products. Organic fertilizer made from straw by microorganism can increase the content of soil organic matter, improve the physical and chemical properties of soil, improve soil fertility, reduce the occurrence of pests and diseases.
Correct use of bio organic fertilizer can improve the output and quality of agricultural products, produce good ecological, economic and social benefits, and make agricultural production to the road of sustainable development. In order to meet the requirements of agricultural ecology, fertilizer factories should pay attention to the following aspects when processing bio organic fertilizers: (1) The types of bio organic fertilizers are developing from single bacteria to compound bacteria. (2) Bio organic fertilizer has developed from single function to multi-function in agriculture. (3) The microorganisms in bio organic fertilizer changed from non-spore bacteria to spore bacteria. (3) Bio organic fertilizer should be developed according to different soil and different crops, pay attention to regional differences in the production of special fertilizers.
