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.
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.
