Abstract:

Soil organic carbon (SOC) is an essential component of soil organic matter and being dynamic in nature controls the nutrients release as well as their availability. Different fractions of organic carbon plays different role in governing the nutrient availability. The various fractions of SOC includes- microbial biomass carbon (MBC), dissolved organic carbon (DOC), light and heavy fraction carbon pool. Among these fraction MBC and DOC fractions are readily soluble or highly mineralizable while heavy fraction carbon constitute the resistant fraction and account higher percentage compared to all other fractions. DOC accounts smallest fraction but it is directly involves in plant nutrition. Microbial biomass carbon was reported higher (430.7 µg g-1) under forest land use system followed by organic farming (230.0 µg g-1) land use system while both these system are significantly higher in MBC as compared to agricultural and riverine land.). Agricultural soil has 50-75% less C stocks compare to reference site which is under native forest. Light fraction carbon (LFC) comprised largely of incompletely decomposed organic residues, may provide a sensitive indicator of the effects of cropping practices on soil organic matter. Soil under no tillage and forest preserved respectively 167% and 94% more LFC than those under conventional tillage. Conversion of native forests and pristine soils to cultivation is usually accompanied by decline in SOC and deterioration of soil structure. Trees had long been found to increase organic carbon, extractable P, and exchangeable cations. The soil solution concentration of N, P, S and several micronutrients are intimately related to organic fraction in soil. Altering land use system have multiple effects on soil properties and nutrients availability.
