  • Effect of land rehabilitation on physicochemical and microbial properties of a sodic soil
  • This study was carried out at Banthra Research Station (BRS) of the National Botanical Research Institute, Lucknow. The goals were (1) to evaluate the effect of long term (5 decades) rehabilitation of sodic land through cropping system on soil
  • properties) of rehabilitated sodic land (RSL) were compared with adjacent degraded sodic land (DSL) and non-sodic soil (NSS). Microbial biomass and enzyme activities were negatively correlated with soil sodicity parameters : pH, EC, exchangeable sodium
  • percentage (ESP) and sodium adsorption ratio (SAR), except alkaline phosphatase activity. Rehabilitation of degraded sodic land through cropping showed 79% (mean gain %) improvement in soil quality. It is concluded that rehabilitation of degraded sodic lands
  • plantations as well as mixed forest. Increase in water holding capacity (WHC), organic carbon, soil nutrients, microbial biomass (MB), microbial counts, CO2 flux and enzymatic activities showed significant improvement in the soil quality of rehabilitated sites
  • . The results showed that afforestation with multiple tree species restored soil properties more efficiently than monoculture plantations, and is a relatively good option for sustainable rehabilitation of sodic lands.
