In the present study, species-specific carbon sequestration efficiency of eight most extensively cultivated agricultural plants in East Kolkata Wetland (EKW) ecosystem has been measured. They altogether sequester about 6343.7 kg ha-1 C, from which 4030 kg ha-1 C is exported from the EKW as edible agricultural product and 2313.6 kg ha-1 C is retained in the field as residual parts. Also, the crop residue of these eight plants contains 373.62 kg ha-1 N, 3.84 kg ha-1 Na, 7.95 kg ha-1 K, 1.85 kg ha-1 Ca, 0.21 kg ha-1 Mg and 2.41 kg ha-1 Fe, 0.36 kg ha-1 Mn and 0.17 kg ha-1 Zn, which enrich the soil micronutrient and may decrease the fertilizer cost. The present study is also aimed at the construction of a beneficial and sustainable crop management system, allowing farmers to get carbon credit from the practice.

Abstract


In the present study, species-specific carbon sequestration efficiency of eight most extensively cultivated agricultural plants in East Kolkata Wetland (EKW) ecosystem has been measured. They altogether sequester about 6343.7 kg ha-1 C, from which 4030 kg ha-1 C is exported from the EKW as edible agricultural product and 2313.6 kg ha-1 C is retained in the field as residual parts. Also, the crop residue of these eight plants contains 373.62 kg ha-1 N, 3.84 kg ha-1 Na, 7.95 kg ha-1 K, 1.85 kg ha-1 Ca, 0.21 kg ha-1 Mg and 2.41 kg ha-1 Fe, 0.36 kg ha-1 Mn and 0.17 kg ha-1 Zn, which enrich the soil micronutrient and may decrease the fertilizer cost. The present study is also aimed at the construction of a beneficial and sustainable crop management system, allowing farmers to get carbon credit from the practice.
