人粪尿肥分高,肥效快,增产显著.一个成年人平均每年排泄粪尿约为800公斤(尿比粪多8倍),其中含氮4.4公斤,约相当于硫酸铵22公斤;含磷1.36公斤,相当于过磷酸钙6.8公斤;含钾1.67公斤,相当于硫酸钾3.47公斤.这是一个极为可观的数字.因此,应重视人粪尿.但人粪尿在保存中,(?)因渗漏和挥发而大量损失肥分.有人试验,把人尿放在缸里,在 Excretion of human excrement fertilizer high, fast fat, yield significant.An average annual excretion of excreta about 800 kg (8 times more urine than dung), which contains 4.4 kg of nitrogen, which is equivalent to about 22 kg of ammonium sulfate; phosphorus 1.36 kg, equivalent to 6.8 kg of superphosphate; potassium 1.67 kg, equivalent to 3.47 kg of potassium sulfate. This is an extremely impressive figure. Due to leakage and volatility and a lot of loss of fertilizer. Some people test, put human urine in the cylinder, at
