There is growing interest in commercial Inland saline aquaculture owing to the availability of vast resources of saline ground water, but Inland saline aquaculture ponds are facing problems of seepage and nutrient deficiency, particularly potassium. Under climate change scenario biochar application for controlling seepage loss and nutrient enrichment will also conserve the carbon pool of the system. Addition of recalcitrant carbon in the form of biochar will sequester the carbon and will not add to the atmosphere through decomposition
In this context, biochar was produced from sugarcane bagasse by pyrolysis at 450oC . The pH, EC, CEC, WHC, available phosphorous and potassium of bagasse biochar was 7.1, 0.62 (dSm-1), 52.7 (cmol(+)kg-1), 185%,1.8 gkg-1 , 19.7 g kg-1, respectively. A 60-days incubation study was conducted to assess the effects of biochar on physicochemical properties of inland saline pond sediment. The bagasse biochar was applied @ 9 t ha-1 and 18 t ha-1. Results show significant increase in organic as well as total carbon in the sediment. Biochar also improved physico chemical properties of sediment.
