Potential Application of Anaerobic Liquid Digestate of Organic Waste to Mediated Soil Salinity

Organic waste such as agriculture residues and fruit and vegetable wastes (FVW) are generated in huge amount and are a source of nuisance to the environment due to their inherent disposal problems. Anaerobic digestion is one of the approaches that could be used to convert raw organic material into useful products. These organic products can be utilized as alternative to traditional agriculture soil amendments such as gypsum which are usually not economical. In the present study, anaerobic liquid digestate (ALD), a mixture of organic material was prepared by anaerobic co-digestion of sugarcane bagasse and fruit and vegetable waste. The mixture was digested under anaerobic conditions for under incubation of 30 oC for three months’ duration. The maximum methane production was (1152 cm3/kg) was observed with under anaerobic co-digestion of bagasse with fruit and vegetable waste. The liquid ALD was obtained in process was used as soil amendment in pot experiment and compared with the gypsum, in order to analyze its efficiency to reduce soil salinity and improve pant growth. The results showed that the use of ALD alone has significantly reduce the soil salinity by lowing EC, SAR and Ca + Mg content of soil. The improvement in soil quality enhanced its potential for high plant growth (wheat) where a significant improvement in plant shoot and root length and leave count was observed. The present study revealed that the organic waste can be utilized to prepare an efficient by product that is economical as compared to traditional gypsum and can be used to reduce the stress of soil salinity and improve plant growth.
