ABSTRACT

Gondia district of Maharashtra has 35.05 % of its area covered with forest. Considerable forest area has been brought under paddy cultivation in the district over time and hence it provides scope for assessing soil carbon stock in forest land and forest to paddy converted land use systems. The present study was aimed to assess the impact of land use and soil management practices on soil properties and consequently on soil quality. The Transects selected were Goregaon, Aamgaon and Salekasa and land uses included Forest, Paddy more than 10 years, Paddy more than 50 years and paddy more than 100 years of cultivation. Replicated soil samples were collected from profiles of four land-use types in all transects. The major production related constraints of the soils developed in mixed alluvium were acidity and inadequacy of nutrient stock. Forest soils were considered as “Control” and used as reference (base level) for the comparative study on C-stock and C-sequestration potentials. Recently converted forestland to paddy (i.e. land under paddy for >10 years) has resulted in highest loss in soil organic carbon (SOC) followed by soils growing paddy for more than 50 and 100 years. Estimated soil carbon stock at 0-30 cm depth varied between 13.5 to 50.2 tonns/ha in Gondia forest, 8.2 to 9.5 tonns/ha in 10 years paddy cultivated area, 12.3 to 12.6 tonns/ha in 50 years paddy cultivated area and 11.6 to 13.3 tonns/ha in 100 years paddy cultivated area which is being lowest in 10 year paddy cultivated area and highest in forest
