Abstract:
The present investigation was carried out to assess the soil carbon fractions including organic carbon, labile carbon viz. permanganate oxidizable carbon and microbial biomass carbon in natural forest, horticulture and agriculture land use systems in Nagaland. Results revealed that soils of natural forest contained maximum amount of organic carbon, permanganate oxidizable and microbial biomass carbon in surface layer followed by horticulture and agriculture land use systems. Significant variation in these fractions was recorded in different seasons. Permanganate oxidizable carbon constituted 2.6%, 2.4% and 2.0% of organic carbon content in natural forest, horticulture and agriculture land use systems, respectively; while microbial biomass carbon constituted 2.5%, 1.9% and 2.3% of organic carbon in natural forest, horticulture and agriculture land use systems, respectively. The results of present study indicated the need for periodical analysis of above parameters for effective soil management to achieve sustainable production of any land use system.
