Sugarcane bagasse biochar: A suitable amendments for inland saline pond water productivity

Abstract

Aim: To ameliorate the inland saline water through biochar for enhancing the pond water productivity and utilize the vast resources of salt affteced land and ground saline water efficiently for aquaculture. Methodology: A 50 days incubation study was conducted to understand the ameliorating effects of sugarcane bagasse biochar on the inland saline sediment and water. Biochar was applied at the rate of 100 g and 200 g in both sediment and water, respectively. Results: Significant (P 0.05) increase in pH,available-N, potassium, available-Pand decrease in total alkalinity was observed in all the treatments. The primary productivity significantly increased (P 0.05) in all the treatments, and the maximum was observed in T4 treatment (0.173 mg m-3). Interpretation: The sediment mixing and water application differ in their effect on the primary productivity and physico-chemical properties of inland saline pond water. The study will help in developing protocol for the application of agro-waste-derived biochar in the inland saline pond aquaculture system.
