Many peasant households understand that if urea and ammonium bicarbonate and other fertilizers are improperly stored and used, they will cause a large loss of nutrients, but they will neglect the manure and fattening work of farmyard manures, resulting in serious loss of nutrients for farmyard manure.
To reduce the loss of nutrients from livestock and manure: Improve the bar ring, so that it does not leak water, no leakage of fertilizer, easy to use washers; bar circle the ground properly, the ratio of excreta and soil to 1:3 ~ 4 is appropriate, Begin working diligently; if the excrement of the slaughter is not used temporarily, the outside mud shall be immediately sealed to ensure fertilizer efficiency.
To reduce the loss of nutrients from human waste: Renovate the toilets and septic tanks to prevent seepage, leaks, and rain, and seal them. Change the method of use, that is, change the dry application to dilute the application, and dilute the decomposed feces. After the application of soil. The decay time is generally 6 to 7 days in summer, and 15 to 20 days in other seasons; it is advocated for the separation of human waste and urine.
Methods to reduce nutrient loss from plant ash: Plant ash contains a large amount of potassium carbonate and is alkaline. Human waste and urine manure are acidic, the two are acid-base neutralized, and nutrients are lost. According to the results, after the plant ash was mixed with human fecal urine at a ratio of 1:1.5, nitrogen loss was about 27.4% for 10 days after storage, and nitrogen loss was about 85.9% for 3 months. Therefore, in the work of composting and composting, we should vigorously promote the single accumulation of grass ash, single storage, and single use. We must not pour ash into organic fertilizer, and at the same time prevent ash from being leached by rain.
