总结一下:(胡乱翻译,非农业生物专业,有错误之处请指正。)
*人尿含有很多溶于水的营养(氮磷钾)相对于粪便
*人尿可以直接用,也可以加入到compost
*加入到compost里的尿可以提高温度,更好地杀死病原体和草籽
*健康人的尿比较粪便卫生,不吸引苍蝇,对很多致病源都不友好
*人尿即便有味道,也会很快消失。尤其是采用新鲜的,稀释的。
#注意不要过量施用。
Urine
People excrete far more of certain water-soluble plant nutrients (nitrogen,
phosphorus, potassium) in urine than in feces.[10] Human urine can be used
directly as fertilizer or it can be put onto compost. Adding a healthy
person's urine to compost usually will increase temperatures and therefore
increase its ability to destroy pathogens and unwanted seeds. Urine from a
person with no obvious symptoms of infection is generally much more sanitary
than fresh feces. Unlike feces, urine doesn't attract disease-spreading
flies (such as house flies or blow flies), and it doesn't harbor the most
hardy of pathogens, such as parasitic worm eggs. Urine usually does not
stink for long, particularly when it is fresh, diluted, or put on sorbents.
Urine is primarily composed of water and urea. Although metabolites of urea
are nitrogen fertilizers, it is easy to over-fertilize with urine creating
too much ammonia for plants to absorb, acidic conditions, or other
phytotoxicity.
