The field experiments on calcareous sodic Vertisols were conducted on
farmer’s fields in Purna valley of Vidarbha region of Maharashtra. The
treatments comprised of different green manures (GMs); crop residues
(CRs); gypsum. The chemical and biological properties after 2 years experiment
showed that the application of gypsum recorded significant drop in
pH and exchangeable sodium percentage (ESP) as compared to organic
amendments. But later has outperformed with respect to biological activities
viz., dehydrogenase activity (DHA) and microbial respiration and
carbon sequestration by enhancing soil organic carbon (SOC), soil organic
carbon (SOC) stock, soil microbial biomass carbon (SMBC) and labile
carbon pool (POXC). Among the different organic amendments the application
of dhaincha improved SMBC by 90%, microbial respiration by 104%,
POXC by 59% and DHA by 265% as compare to control. High ESP of these
soils showed negative relationship with microbial respiration and POXC
(r = 0.48 and r = 0.43, p = < 0.05). While addition of biomass showed
positive relationship with SMBC, microbial respiration, POXC and DHA
(r = 0.93, r = 0.81, r = 0.83 and r = 0.91 p = < 0.01). The results of study
showed green manuring in sodic black soil found to be alternative choice
to gypsum, which besides gradual reclamation also enhance biological
properties and carbon sequestration.
