Organic fertilizer:
1) It contains a lot of organic matter, which can improve soil fertility;
2) It contains a variety of nutrients and the nutrients are balanced in an all-round way;
3) The nutrient content is low, so it needs a lot of application;
4) The fertilizer effect time is long;
5) It comes from nature and there is no chemical compound in the fertilizer. Long term application can improve the quality of agricultural products;
6) In the process of production and processing, as long as it is fully decomposed, the ability of drought resistance, disease resistance and insect resistance of crops can be improved, and the amount of pesticide used can be reduced;
7) It contains a large number of beneficial microorganisms, which can promote the bio-transformation process in the soil, and is conducive to the continuous improvement of soil fertility;
Chemical fertilizer:
1) It can only provide crop inorganic nutrients, and long-term application will have adverse effects on soil, making the soil "more greedy";
2) Because of the single nutrient species, long-term application will easily lead to nutrient imbalance in soil and food;
3) The nutrient content is high and the application rate is low;
4) The fertilizer effect period is short and fierce, which is easy to cause nutrient loss and pollute the environment;
5) It is a kind of chemical synthetic substance, and improper application can reduce the quality of agricultural products;
6) Long term application of chemical fertilizer can reduce the immunity of plants, which often requires a large number of chemical pesticides to maintain the growth of crops, which is easy to cause the increase of harmful substances in food;
7) Inhibition of soil microbial activities leads to the decline of soil automatic regulation ability.
