摘要：Detailed study was carried out in the southern districts of Tamil Nadu agricultural soils for the carbon sequestration potential of important fodder crops throughout the year of both perennial and annual origin. Fodder maize, fodder cowpea (annual crops), hedge lucerne (Desmanthus virgatus) and hybrid Napier (CO-4) (perennial crops) was cultivated in Seevanallur and Ramayanpatti regions of Tirunelveli district and Srivilliputhur and Rajapalayam regions of Virudhunagar district. The soil organic carbon estimated prior to cultivation ranged from 0.24 to 0.28%. The percentage of soil organic carbon sequestered by the fodder crops were found to be enhanced in Virudhunagar district than in Tirunelveli district. Hybrid Napier sequestered higher amounts of carbon when compared with hedge lucerne, fodder cowpea and fodder maize. The rate of carbon sequestered by hybrid Napier ranged from 0.92 to 1.24. Hedge lucerne sequestered 0.90 to 1.17. The rates of carbon sequestered by fodder maize and fodder cowpea were 0.07 to 1.14 and 0.19 to 0.99, respectively. Hybrid Napier and hedge lucerne contain higher amounts of protein, thereby increasing the growth and milk yield properties of livestock in the land owned farmers of the villages. The organic carbon content was high in hybrid Napier and hedge lucerne when compared with fodder maize and fodder cowpea. Agriculture has a higher potential of sequestering carbon from the atmosphere with the limited and application of scientific advancement combined with organic farming, including no-tillage or less tillage will enhance the reduction of carbon dioxide in the atmosphere.
