How to make self-made organic fertilizer?
The ripening of organic fertilizer changes in two aspects through the activities of microorganisms: on the one hand, the decomposition of organic matter increases the effective nutrients in the fertilizer; on the other hand, it makes the organic matter in the fertilizer change from hard to soft. texture from uneven to uniform, and in the maturity of weed seeds and bacteria, insect eggs.

There are different uses of micro-fertilizer.
In recent years, the problems of wheat seed burning and seedling burning occurred frequently in autumn seeds, which caused 20% ~ 30% of the lack of seedlings and broken ridges, and the serious ones had to be sown again and again, and this problem showed an upward trend. In order to pursue high yield and higher yield, some farmers one-sidedly think that they can get high yield as long as they apply more fertilizer, regardless of the abundance and deficiency of nutrients in the land.

Immiscible fertilizers in agricultural production
The pure urea is white crystal, the industrial product is white or yellowish small particles, and the nitrogen content is 44Mel 46%. It is a neutral fertilizer with low hygroscopicity and soluble in water. It is the variety with the highest nutrient content in solid nitrogen fertilizer. Because of fast foliar absorption, high utilization rate and high yield increasing effect, it is the most suitable to be used as extra-root topdressing. The concentration of spraying should be root.

What should be paid attention to in the process of fertilizer application and mixing?
There are many problems worth paying attention to in the process of fertilizer application. Specifically, we should find out which fertilizers can be mixed and which can not be mixed. The mixed application of ammonium bicarbonate and calcium superphosphate can not only absorb nitrogen, phosphorus and other nutrient elements, but also neutralize part of the free acid in calcium superphosphate and eliminate its harm. But it should.
