Abstract Human excreta are a natural resource which is always available in all societies. Unfortunately, their value is highly underestimated in present agriculture and horticulture including in many tropical developing countries. Especially human urine is rich in nitrogen. This "free" fertiliser should be used as much as possible and needed. In many cases, human urine and composted human faeces could be fortified with wood ash and kitchen and garden waste to meet the potassium and phosphorus needs of plants and to improve soil structure. Avoiding health risks and dosage requirements are also discussed. The ideas presented here can be used even with the cheap pit latrines that are common in the rural and peri-urban areas of developing countries. They do not require electricity and/or tap water. They may also fit conditions in areas of Eastern Europe where piped water and sewerage are absent and/or people lack money for fertilisers and maintenance of wastewater treatment plants.
