1. Prevent nutrient loss caused by gas volatilization
Compost fermentation is the first step of organic fertilizer manufacturing machinery. In the process of decomposition, the internal nitrogen will be converted into ammonia, resulting in volatilization loss. Therefore, it must be covered tightly with undamaged plastic film during decomposition. And the accumulation of decomposition time should not be too long, and should be used as soon as possible after decomposition.
2. Prevent nutrient loss caused by chemical reaction
Ordinary manure and plant ash cannot be mixed. Plant ash contains a lot of potassium carbonate, pH value is alkaline, feces and plant ash mixed, acid and alkali neutralization, nutrient loss. Therefore, manure and plant ash should be stored separately in the process of stacking production. Plant ash should not be poured into organic fertilizer, and should also be prevented from being drenched by rain.
3. Prevent nutrient loss through water leakage
In order to make rice husk, sheep dung, duck dung and cow dung easier to decompose, the fertilizer is watered in the production of organic fertilizer, but usually due to the lack of anti leakage measures under it, the nutrients are lost due to water leakage. Therefore, whether it is decomposed in the sewage pit or on the flat ground, a layer of plastic film must be placed under it to prevent the leakage of nutrients with the water. In addition, a proper amount of water must be sprayed.
After composting, the material is made into solid particles by drum granulator, which is more conducive to the storage of fertilizer, and the long-term supply of nutrients should be ensured.
