One of the benefits of phosphate fertilizer stacking is to improve fertilizer efficiency. Organic fertilizers produce a large amount of organic acids in the process of decay, which can promote the decomposition and transformation of insoluble phosphorus, which is beneficial to the absorption and utilization of crop roots and reduce phosphorus fixation. The second is to avoid burning seedlings. Superphosphate contains more free acid. If it is applied directly, the dosage is slightly larger and it is easy to burn and burn. This phenomenon can be avoided if the phosphate fertilizer is mixed with the manure. The third is to increase nutrients. Phosphate fertilizer has a single component, while organic fertilizer has complete nutrients. When mixed, the two can meet the needs of crops for various nutrients, and can also use nitrogen to protect nitrogen, promote nitrogen with nitrogen, and reduce nitrogen volatilization.
Stacking method If the livestock and poultry manure is dry, first crush it and the phosphate fertilizer separately, mix it into a pile in a ratio of 3:1, cover the surface with a layer of fat mud, and then seal the surrounding with ordinary soil, and make the top of the pile concave. hole. Pour the human and animal waste into the hole, the amount of pour is not exuded, and finally the top is sealed with mud. Turn it 10 times after 10 days. If it is too dry, add some excrement. Generally, it is stacked for 20 days in summer and 25 to 30 days in winter.
