Soil Health Management through in-situ Sugarcane Trash Composting

Due of a shortage of labour and time available for seeding the following crop, sugarcane trash burning inside the field is a typical practise among Indian farmers. This is a risky practise that has affected soil health, air quality, and human health, as well as causing huge economic losses. The current study was based on primary data acquired from sugarcane growers in order to highlight the issues and investigate the impact of in-situ sugarcane garbage composting on soil fertility and cane productivity. Traditional conventions, a lack of information about waste utilisation, a lack of technology, and the high cost of machinery have all been identified as important factors in the practice’s persistence. In-situ sugarcane garbage composting raised the organic carbon, available N, available P, and available K content in soil from 0.42 to 0.45 percent, 317 to 331 kgha-1, 14.5 to 16.1 kgha-1, and 520 to 551 kgha-1, respectively, according to the findings of demonstrations in ten farmers’ fields. In the demo field, the average cane yield was 92.5 tha-1, which was 4.8 percent higher than the control plot (88.3 kgha-1). The benefit cost ratio of 2.99 improved gross income by 4.7 percent above the control plot, according to the economic study. As a result, in-situ composting may be a viable option for addressing these issues. In-field composting and waste mulching in sugarcane fields may be a viable option for addressing these issues. Farmers indicated that some of the solutions to cope with the problem include raising awareness among farmers about environmental loss and stringent enforcement of the law preventing the burning of agricultural residue, custom renting of expensive machinery for chopping straw, and off-farm utilisation.
