The organic part of the fertilizer is not very high. The organic content of most organic and inorganic compound fertilizers is about 50%. If 50% is applied in 50%, the organic matter applied is only 100 kg. Many tests have shown that it is effective to apply 1500 kg of organic fertilizer per acre. It can be seen that the organic matter applied by the organic-inorganic compound fertilizer can have a limited fertilizer effect.
The microbial agent does not have much microorganisms to be active under certain circumstances, and the environmental requirements are relatively high. Most of the chemical fertilizers are salts, which have high solubility and can kill or inhibit the activity of microorganisms.
The effect of fertilizer is mainly the role of inorganic fertilizers. Organic and inorganic compound fertilizers are a variety of compound fertilizers. For most crops, 100 kg of compound fertilizer with a ratio of 10:6:9 NPK can be used to meet the high production level. At this time, the organic matter is only 50 kg per mu. It is conceivable that if there is no inorganic fertilizer in the fertilizer, the amount of organic part is useless. Therefore, when applying organic-inorganic compound fertilizer, first pay attention to the nutrient content and proportion in the fertilizer, while considering the price and application effect.

The effect of spring tillage on compound fertilizer is heavy
Organic-inorganic compound fertilizer refers to a compound fertilizer containing organic substances and inorganic nutrients. Most of the organic materials use processed organic fertilizers (such as livestock manure, straw, etc.), as well as organic matter (cemocarbon, weathered coal, humic acid, etc.), and some also add microbial agents and substances that stimulate growth; inorganic nutrition Part is mainly chemical fertilizer.
