The organic inorganic compound fertilizer not only contains the inorganic nutrients, such as nitrogen, phosphate, potassium, sulfur, calcium, magnesium, zinc, ferrum, boron, copper, molybdenum, but also is rich in organic matters, amino acids, humic acids, such that it has complete and balanced nutrients. It owns the quick effect as like inorganic fertilizer, and the long-term efficiency as like organic fertilizer and the special effect as like amino acids. According to the local soil fertility and seasonal crop fertilizer demand, the organic inorganic compound may combine with the proper amount of chemical fertilizer for application, which can meet the nutrient requirements of the whole growth period of crop. Besides, according to the local fertilization habits and the situation of agriculture, it is suitable to select granular fertilizer, foliar fertilizer or water flush fertilizer for bottom fertilization, top dressing or spreading fertilization, ditch fertilization, hole fertilization, foliar fertilization, and irrigation fertilization, which are flexible and efficient.

A large number of studies have shown that long-term application of chemical fertilizers exerts a serious effect on soil secondary salt loss, soil acidity and soil structure, resulting in soil sealing and fertility decline. When the organic matter content is more than 1%, the soil is healthy soil, between 1% and 0.5%, sub-healthy soil, below 0.5%, sick soil. In many areas of China, the soil has tended to be sick, which is the mainly cause for the high difficulty of increase in the yields, and the decline in the quality of agricultural products. Hence, the rich organic matter means the fertile soil; the poor organic matter means the lean soil. The organic inorganic compound fertilizer contains plenty of organic matters, which can effectively improve the soil agglomeration structure, soften the soil, promote the soil, increase the soil permeability and improve the soil’s water and fertility conservation function. In particular, it can increase the yields and quality of peanut and tuber crops
