The research project, The concentration of nutrients N, P, K in solid organic waste from selective market ayaymaman using the technique of composting, specific objectives: Perform classification by sectors Generation of Solid Organic Waste , in the City Market ayaymaman Moyobamba; build processing Composting of Solid Organic Waste; determining concentrations of N, P, K, pH, electric conductivity and organic matter contained in the compost. The problem statement was: What is the concentration of nutrients in selective organic solid waste from ayaymaman market? The variables were: Independent Variable Xi: Branches of study. And dependent variable Yi: concentration of nutrients N, P, K, EC, pH and organic matter. The hypothesis to prove If we make compost Organic Solid Waste selective ayaymaman from the market, then the concentration of nutrients N, P, K are significant. The methodology con...
