Abstract:
An survey entitled "Studies on aggregate stability in soils of Nandurbar District and their correlation with available nitrogen and soil organic carbon" was conducted between 2019 to 2022. Total 21 soil samples were collected from 0-15 cm depth and exact locations of samples site was recorded by GPS device. The results indicated that about 17 samples (80.95%) reported low aggregate stability (MWD) and only 4 samples (19.05%) reported good aggregate stability. While the bulk density of soil ranged from 1.27-1.50 Mg m^-3. The organic carbon content, available N, P and K ranged between (2.5-9.4 g kg^-1 soil), (145.5-215.9 kg ha^-1), (8.2-22.4 kg ha^-1) and (302.4-672.0 kg ha^-1), respectively. Whereas, the Water Soluble Carbon (WSC), Soil Microbial Biomass Carbon (SMBC), Permanganate Oxidisable Soil Carbon (POSC), Particulate Organic Matter Carbon (POMC), Humic Acid Carbon, Fulvic Acid Carbon and Total Organic Carbon (TOC) were ranged from 2.24 to 6.28 mg kg-1, 138.52 to 440.87 mg kg-1, 432.00 to 614.25 mg kg-1, 1.42 to 2.93 g kg^-1, 80.5 to 163.9 g kg^-1, 61.5 to 133.2 g kg^-1 and 4.45 to 23.35 g kg^-1, respectively.
