Correct mixed fertilizer synergy method
PDC cutters for geology and coal mining have high abrasion resistance and impact resistance through adopting advanced international technology. Meanwhile we have improved the structure of interface combination between polycrystalline diamond layer and tungsten carbide substrate which can improve the distribution of stress and make the interface firm and steady. So coal mining pdc cutter of production are reliable, durable for years while high cost -effective.

2. Add calcium phosphate to human excrement. Adding 5%-10% of superphosphate to human excrement can not only reduce the evaporation of ammonia in human excrement, but also supplement phosphorus nutrition, which complement each other.
3. Superphosphate and ammonium sulfate. When superphosphate is mixed with ammonium sulfate, a part of monoammonium phosphate and calcium sulfate will be formed, which can simultaneously supply crop nitrogen and phosphorus, and partially improve the physical and chemical properties of the two fertilizers.
4. Superphosphate and phosphate rock powder. The combination of superphosphate and phosphate rock powder can ensure the need of phosphorus in the seedling stage of the crop, and the latter can meet the needs of the crop growth period, so that the whole growth period of the crop is not deficient in phosphorus.
5. Organic fertilizer and ammonia. Mixing 3-4 kilograms of organic fertilizer plus ammonia water per 100 kilograms can reduce the volatilization of ammonia, regulate the carbon and nitrogen ratio of organic fertilizers, and accelerate the composting of compost.
6, phosphate rock and ammonium sulfate. The combination of phosphate rock and ammonium sulfate can not only eliminate the physiological acidity of ammonium sulfate, but also enhance the fertilizer efficiency of phosphate rock, which is beneficial to crop growth and development.
7. Ammonium bicarbonate and urea cannot be mixed. The amide nitrogen in urea cannot be absorbed by crops, and it can only be used by crops after being converted to ammonium nitrogen by the action of urease in soil. After the ammonium bicarbonate is applied to the soil, the soil solution is acidic in a short period of time, which accelerates the volatilization of nitrogen in the urea, so it cannot be mixed.
8. Ammonium bicarbonate should not be mixed with bacterial fertilizer. Ammonium bicarbonate and bacterial fertilizer are enemies, because ammonium bicarbonate will emit a certain concentration of ammonia gas, which has a toxic effect on the active bacteria of the bacterial fertilizer. If mixed, the fertilizer will lose fertilizer efficiency.
