摘要: This laboratory scale experiment was designed to study the suitability of organic wastes from paper and food seasoning industries to improve the soil organic carbon for rice cultivation. Lignin-rich wastewater from paper industry and nitrogen-rich effluent from a food industry at suitably lower concentrations were used at two levels of green manure to enhance the soil organic carbon fraction over time. Both the groups of soils with or without Sesbania were incubated under submerged condition at 25 degrees C for 15 days. Wastewaters from paper industry (WP), food industry (WS), and a combination of WP + WS were added separately to both the treatment groups in flasks. After 103 days of incubation, from all the three treatments and control, total organic carbon and alkali-soluble organic carbon fractions were analyzed. Results indicated that in all the three treatments containing green manure amended with industrial wastewaters, the organic carbon content increased significantly. The alkali-soluble organic carbon fraction was increased by 59% in the soil amended with green manure containing WS and by 31% in the treatment without green manure compared to control. The paper mill waste water namely, WP, increased the organic carbon only in the soil containing green manure by 63%. The combined treatment of WP + WS with green manure increased alkali-soluble organic carbon fraction by 90% compared to control, while in the treatment without green manure, the organic carbon increase was 71%. Overall, the combined treatment WP + WS with green manure could increase the alkali-soluble organic carbon fraction more than all other treatments. Hence, wastewater rich in organics from paper and food industries can be efficiently used to temporarily increase the soil organic carbon content. (C) 2007 Elsevier Ltd. All rights reserved.
