Abstract
Rwanda, same to other corners of the worlds has awareness to use organic fertilizers (composts) both for nutrient supply to plant (fertilizers) and for improving soil physical conditions (soil amendment). This has pushed the government of Rwanda and private sectors working in Rwanda to put more effort to boost the production and use of compost. However, the demand rate is increasing than the production rate due to the insufficient and accessibility of row materials and sometimes to the lack of awareness and skills for small farmers. Moreover The sanitary products (i.e toilet waste) has recently and currently seen as a low-cost alternative to supplement available composts in different countries of the worlds and in Rwanda and if these products are not managed carefully, underground water pollution, waste of land for new pits and waste of water for flashing toilets will continue to occur. The aim of this study was to assess the effects of human compost on the some soil chemical properties and on green bean productivity compared to other available composts (cow and vermicompost). The treatments were control (without any compost), human compost, cow compost and vermicompost. The effect on soil chemical properties were assessed by sampling soil in the cultivated plot and bring them to laboratory for analysis of soil pH and electrical conductivity (EC) whereas effect on green bean yield was assessed by counting number of pods and their weight for each treatment. The results showed that there is a significant increase of soil pH, soil EC and organic carbon in soil under human compost than in other composts for (0-15) cm depth. Concerning the effect on green bean yield, the yield obtained in plot amended by human compost was significantly higher than that obtained in plots amended by cow compost and vermicompost, meaning that the fertilizer value of the sanitary products was higher than that of available composts. Sanitary products (human waste) can be reused as nutrient source and soil amendment but care must be taken on its salinity.
