Nitrogen and Phosphorus Availability of Biologically and Thermochemically Decomposed Human Wastes and Urine in Soils With Different Texture and pH

Human waste contains ample plant-available nitrogen (N) and phosphorus (P), which can be used to address soil nutrient deficiencies. Biological and thermochemical sanitization methods have been proposed for safely treating the solid fraction of human waste (called human solid waste [HSW] in this study) but have rarely been compared directly. Furthermore, interactions between amendments and soil properties are also unclear, as pH, texture, and...
