Three different types of organic wastes that are abundant in Mizoram were selected. They were the sheaths of Dendrocalamus hamiltonii, Amomum dealbatum, and Zea mays. They were shredded and dried to constant weight and amended with soil in a 5-year-old jhum fallow. In the study, it was found that the amendment of Amomum residues leads to more enrichment of organic carbon in the soil. By comparing between the unamended and amended soil, there was more organic carbon, nitrogen, and phosphorus in 242the soil of amended plots. This indicates that jhum fallows can be reclaimed and a new cropping pattern can be established by treatment of organic wastes.
