This study was designed to check the effect of different C:N on the maturity of compost. The organic waste treated with different C:N give different results at the end of composting. The four windrows of organic waste were treated with C:N of 35:1, 35:1, 33:1 and 30:1. The substrate used was same in all the windrows. It was concluded that the more mature compost was given by the windrow one and two with optimized C:N of 35:1. Copyright@ International Science Community Association
