Abstract:

In the study soil surveys conducted and GPS based soil samples were collected from each domain viz., Bhopal, Hoshangabad, Vidisha and Jabalpur of AESR 10.1 region.and for bulk density (BD), total porosity (TP), particle size distribution (Sand, Silt, Clay), analyzed then aggregate stability (AS) and structural stability index (SSI) were estimated in the Department of Soil Science and Agricultural Chemistry Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during 2018-2020. The results noticed that the highest mean values of sand silt and clay (40.31, 28.71 and 43.22%) were recorded in cultivated land of Bhopal, Hoshangabad, and Jabalpur domains, respectively. The mean bulk density of the soils ranged from 1.47 and 1.50 Mg m-3 and the mean total porosity ranged from 43.30 to 44.83%, which indicated the less soil compaction. The AS ranged from 39.55 to 43.79 with whole mean value of 41.02% while the mean values of SSI (1.52%) with ranged from 1.19 to 2.39%. The average values of 32.12, 26.64 and 41.25 sand silt and clay and its ranged from 16.00 to 51.84, 13.28 to 38.90, and 23.44 to 58.00% in AESR10.1 as a whole region, respectively. The BD, TP, SSI and AS% of soil under the AESR region was found in ranged from 1.34 to 1.71 Mg m-3, 35.47 to 49.43%, 0.66 to 3.70 and 35.06 to 46.86% with mean values of 1.48 Mg m-3, 44.10%,1.52 and 41.02% categorized BD in the little high that might be due to clod methods adopted which gave higher BD. Geo-statistical results showed that the Gaussian model best fitted for of SSI and AS, Spherical model fitted for BD, Sand, Silt, Clay and exponential model fitted for TP in Bhopal domain. In Jabalpur domain, exponential domain best fitted for BD, TP, Clay and SSI, Spherical model for Sand and Silt, and for AS, Gaussian model is best fitted. In Vidisha domain, exponential model best fitted for BD, Silt, Clay and SSI, Gaussian model best fitted for of TP, Sand and AS while in Hoshangabad domain, exponential model is best fitted for TP, Clay, SSI, and AS, and Gaussian model best fitted for BD, Sand and Silt. The nugget/sill (N/S) ratio <25% which exhibit strong spatial dependency(SD) only for Sand, Clay and AS in Bhopal domain. The N/S ratio was found to be >25% but <75% which showed moderate SD, for BD, Silt and SSI in Bhopal domain, BD, TP, Sand and Silt in Jabalpur domain, AS and SSI in Vidisha domain, and Sand, Silt, Clay, AS and SSI in Hoshangabad domain. The N/S ratio was found to be <75% which showed weak SD for Clay, AS and SSI in Jabalpur domain and TP in Bhopal domain, BD, TP, Sand, Silt, and Clay in Vidisha domain, and BD and TP in Hoshangabad domain. Irrespective of domain cropping system and management practices were varied and have adverse effects on physical properties. Therefore, the proper soil conservation practice is important to enhance soil fertility and crop productivity.
