Organic fertilizers and chemical fertilizers are both fertilizers, what is the difference between them?
Organic fertilizer refers to fertilizer derived from animal and plant residues, excrement or biological waste, and made through microbial action or natural fermentation process. ‌It mainly includes livestock and poultry manure, crop straw, green manure, vermicompost, kitchen waste, urban sludge, etc. Organic fertilizers eliminate toxic and harmful substances through microbial decomposition and fermentation, and are rich in a variety of organic matter and nutrients, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc., as well as various trace elements and beneficial microorganisms. ‌‌

Chemical fertilizers are obtained from natural ores or synthetic raw materials. They mainly include nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, micro-fertilizers and compound fertilizers. The main components of chemical fertilizers include nitrogen, phosphorus, potassium and other nutrients. These elements are called the "three elements of fertilizer". Chemical fertilizers have high nutrient content and are fast-acting, but some fertilizers may have acid-base reactions. ‌
The main differences between organic fertilizers and chemical fertilizers lie in their composition, fertilizer efficiency, impact on soil and environmental friendliness. ‌

Organic fertilizer‌: mainly derived from plants and animals, contains a large amount of organic matter and a variety of nutrients, has a long fertilizer effect and is slowly released. It contains nitrogen, phosphorus, potassium and other nutrients and trace elements. Because organic fertilizer will go through two steps during the fermentation process, one is mineralization, which will produce all the nutrients needed by plants, and the other is humification, which will produce humus and can increase the soil's aggregate structure. It is very nutritious, but it is not enough. It is suitable for use as a base fertilizer, but it cannot meet the large needs of crops during the critical growth period. ‌‌‌Chemical fertilizers‌: Mainly synthesized through chemical methods, containing high concentrations of inorganic salts, the fertilizer effect is fast and concentrated, but the duration is short. Chemical fertilizers have a single type of nutrients, mainly providing nitrogen, phosphorus, potassium and other large amounts of elements, and are suitable for use during the critical period of crop growth.

Organic fertilizer‌: Long-term application can improve soil structure, increase soil biodiversity, and promote soil fertility. It contains beneficial microorganisms that promote biological transformation processes in the soil and contribute to the continuous improvement of soil fertility. ‌‌‌Chemical Fertilizers‌: The more you use chemical fertilizers, the more you will eat them. Long-term application may cause the destruction of soil acid-base balance, reduce soil biodiversity, inhibit soil microbial activity, and reduce the self-regulating ability of the soil.
‌Organic fertilizer‌: Derived from nature, does not contain any chemical synthetic substances, is environmentally friendly and will not cause pollution. It can improve the quality of agricultural products and reduce the use of chemical pesticides. ‌Chemical fertilizer‌: It is a pure chemical synthetic substance. The ingredients are minerals. When put into the ground, they will accumulate. Especially ammonium salts, which contain salt. Excessive use may cause soil hardening and water pollution. Long-term improper use will reduce the quality of agricultural products. The more they are used, the more they will be used, and more and more fertilizers will be added, but the yield will not increase.

‌Organic fertilizer is suitable for use as base fertilizer. Long-term application can improve soil quality, but it cannot replace chemical fertilizers. Chemical fertilizers are suitable for use during the critical growth period of crops to meet the needs of rapid growth, but their duration is short, and they cannot replace organic fertilizers. ‌‌The combined use of organic fertilizers and chemical fertilizers can complement each other's strengths, comprehensively supply the nutrients needed for crop growth, improve production efficiency, and reduce nutrient loss and environmental pollution. ‌‌
