农家肥有效成分含量低,肥效迟缓。如果给农家肥加一点“添加剂”,不仅能防止有效成分的挥发流失,而且还可使肥效成倍地提高。人粪尿添加硫酸亚铁。在每100公斤人粪尿中加硫酸亚铁500—600克,可使人粪尿中碳酸铵转化成性质稳定的硫酸铵,起到保肥除臭、防止氮素挥发的作用。人粪尿中添加过磷酸钙。在100公斤人粪尿中加入5公斤过磷酸钙,搅拌均匀存3—10天,能使人粪尿中极易挥发的碳酸铵转化成性质稳定的磷酸铵,增加人粪尿的磷元素,以磷保氮。
Active ingredients of low-fat manure, fertilizer slow. If you add a little fertilizer to the farm “additives”, not only to prevent the loss of volatile organic compounds, but also can double the efficiency of fertilizer. Human waste added ferrous sulfate. In every 100 kg of human excrement plus 500-600 grams of ferrous sulfate can make human excrement of ammonium carbonate into stable ammonium sulfate, play a fat and deodorant to prevent the role of nitrogen volatilization. Human urine add superphosphate. In 100 kg of human excrement by adding 5 kg of superphosphate, mixing evenly stored 3-10 days, can make very volatile man-made urine ammonium carbonate into stable ammonium phosphate to increase the phosphorus of human excretion of phosphorus, To phosphorus nitrogen.
