Abstract: The organic carbon management in the soil and its relationship with soil physiochemical and biological characteristics to increase the crop productivity have been described based on the byproducts of sugarcane. In this chapter, the available information on the nutrient content especially the organic carbon of various by-products of sugarcane, paves the way for incorporation of waste materials and its compost for improving the soil fertility by soil scientists and agronomists, and further, the ecologists will realize the importance of sugarcane waste and its meritorious characteristics of toxic residue free soil and food products in addition to reducing the emission of greenhouse gases to the atmosphere, especially methane and nitrous oxides due to applied of synthetic fertilizer in the cultivating field. We have compiled the information on relationship between organic carbon and soil characteristic, factors responsible for depletion of soil organic carbon and its management. The composting process for sugarcane press mud, bagasse, and trash to produce nutrient-rich manure for soil fertility management and its value on saving the purchase of chemical fertilizer leads to easy adoption of organic farming. Overall, we emphasized the importance of waste products of sugarcane and it's nutritive value to increase the soil fertility, crop productivity, and farm income.
