The residual effect on soil properties on application of composts made out of composting enzyme industrial wastes and municipal solid wastes namely MEES compost (multiple effect evaporator salts + municipal solid waste) and primary sludge (PS) compost (Primary sludge + municipal solid waste) were evaluated in this study. Application of composts recorded a marginal increase in soil pH towards harvest ( and in treatment T8 (50% N through MEES + 50 % N through FYM and T7 (PS compost @ 10 t ha-1 ) respectively) in comparison to the initial pH and a higher organic carbon content of and per cent at 30 DAS and and in T6 (MEES Compost @10 t ha-1 ) and T7 (PS Compost @ 10 t ha-1 ) respectively after the harvest of cowpea which was grown as the residual crop. A positive residual effect was evident in compost treatments with an increased status of available major and micro nutrients. | Application of enzyme industrial waste-municipal solid waste composts Residual effect on physico-chemical properties of soil
