Nutrient loss caused by gas volatilization The nitrogen in the organic fertilizer will be converted into ammonia during the decomposing process, causing volatilization loss, so when it is decomposed, it must be covered tightly with an undamaged plastic film. And the accumulation of decomposing time must not be too long, use as soon as possible after decomposing.
The loss of nutrients caused by chemical reactions, human feces, urine and plant ash are examples. Many vegetable farmers still pour some plant ash in human feces to prevent flies or peculiar smells in human feces. Plant ash contains a large amount of potassium carbonate, and the pH value is alkaline; human feces and urine are acidic organic fertilizers, so when the two meet, the acid and alkali are neutralized, and a lot of nutrients are lost.
Nutrients like rice husk dung, duck dung, cow dung, etc. are lost due to water leakage. In order to be more prone to decomposing, the common people will water the pile of manure, but often because of the failure to prevent leakage underneath. As a result, nutrients are lost with water leakage. Therefore, a plastic film must be laid below to prevent the nutrient from leaking with the water, and the amount of water must be sprayed.
