Tentative guidelines for agricultural use of urine and faeces

Salomon, H; Richert-Stintzing, A; Vinnerås, Björn; Jönsson, Håkan


Plant nutrients are a necessary input in high-productive and sustainable crop production. The plant nutrients in both urine and faeces emanate from arable fields and thus should be recycled as fertilisers to support sustainability and to retain the fertility of the fields. This paper presents tentative general guidelines for use of urine and faeces as fertiliser. Urine is a quick acting fertiliser rich in nitrogen, and with a composition of nutrients that well matches the needs of many crops. Urine and faecal matter well supplement each other, since faecal matter is slower and rich in phosphorous and potassium. It also contains organic matter and will increase the buffering capacity and the organic matter of the soil. Faecal matter should be sanitised before reuse, since it can contain high concentrations of pathogens. More research on use of urine and faeces is needed in order to make the recommendations more detailed and to develop new ways to efficiently use human excreta in agriculture. The guidelines are developed by EcoSanRes, a programme supported by Sida
