A field experiment was conducted during 2023-24 at MHREC, UHS main campus, Bagalkot district. The study entitled “Studies on potential carbon stock assessment and soil fertility status under different land use ecosystem in Northern dry zone of Karnataka”. The experiment was conducted with nine treatments and four replications using randomized complete block design. The primary objectives were to compare soil fertility status, soil carbon stocks and their relationship under different land use ecosystem. The results of soil fertility status of different land use ecosystems indicated that the soil reaction was found highest in the rhizosphere of mango ecosystem (8.37) and EC was found highest in the rhizosphere of grape ecosystem (0.56 dSm^-1). The organic carbon (7.80 g/kg) was highest in the rhizosphere of teak ecosystem compared to other treatments. Lower bulk density (1.28 Mg/m³) and higher water infiltration rate (1.51 cm/hr) were found in teak ecosystem. The highest above ground biomass (343.00 t/ha) and below ground biomass (85.75 t/ha) were recorded in coconut ecosystem. The highest soil organic carbon stock (1.50 t/ha) were found in the rhizosphere of teak ecosystem compare to all other ecosystem. On the basis of overall assessment of results, it could be concluded that the teak ecosystem shows the best result for capturing carbon stock in soil which help in maintaining soil fertility status.
