Abstract
Abstract : The present study was carried for characterization and classification of soils for suitability and alternate land use planning in tribal area of Dharnitahasil of Melghat in Amravati district of Maharashtra state. Sentinel-2A satellite data of study area obtained from Maharashtra Remote Sensing Center, Nagpur was used to identify probable profile sampling sites. However profile sampling sites were finalized with help of ground truth and based on the variation in soil-site characteristics and different land use systems.Twenty Four (24) representative sites were selected on different land use system and the study area classify into three broad categories of land use viz., agricultural land, forest land and scrub land, respectively. The agricultural crop land was further divided into I) single cropping II) double cropping and III) triple cropping.
The soil occurring on very gently to gently sloping undulating land, slope and lower topographic position are moderately deep to very deep, moderately well drained to well drained, very dark greyish brown to light brownish grey in colour, and have clay to clay loam textural class and classified as TypicHaplusterts and Typic/VerticHapulsteps. The soils occurring on gently to moderately steeply sloping landscapes and isolated hillocks are very shallow, somewhat excessively drained, reddish brown in colour, and have clay loam to sandy clay loam textural class and classified as TypicUstorthents.
Soils were evaluated for their fertility, land capability, irrigability and suitability classes for the crops grown in the area. The bulk density of soils was medium to moderately high, pH was slightly acidic to moderately alkaline and the EC of soils was generally low. It was observed that, the organic carbon in surface soils varied from 0.25 to 1.06 %, which indicated that, soils were medium to high in organic matter content. The ESP of soils was low and it increased with the soil depth. Available nitrogen and phosphorus was low to very low and potassium content in soils was high to very high. The available micronutrients viz. (Fe. Mn, Zn and Cu) were medium to high.
A nutrient index value indicated that, nutrient index of available nitrogen and phosphorous was low, available Fe and Zn was moderate, CaCO3 & OC are moderately high, available Mn was high and available K and available Cu was very high.
The soils are grouped into land capability class III, IV,VI, VIII and ) land irrigability classes B(2),C( 3),D( 4) and E(5. The soil suitability evaluation indicates that, the Dharnitahasil soils are highly suitable for sorghum and soybean/ green gram based cropping system with cultivation of wheat and chickpea as a double crop and cultivation of summer groundnut, summer green gram as triple crop based on availability of irrigation. Suggested land use plan of the Dharnitahasil has been prepared considering available natural resources and their evaluation for optimum utilization and management. Sustainable management of natural resources along with livelihood security of farmers of tribal area. This developed land use plan may be helpful in better agro technology transfer on similar soils under similar agro climatic conditions of the region.
Description
Description : The present investigation was carried out in Dharnitahasil of Melghat to characterize and evaluate the land resources namely land use/land cover, physiography, slope, and soils using of Sentinel -2A satellite data and ground truth verification. Spatial variability in available macronutrients (N, P, K) and micronutrients (Fe, Mn, Cu, Zn). The soils were evaluated according to land capability, land irrigability, soil productivity and soil-site suitability for growing cotton, pigeon pea, soybean, green gram, sorghum, gram, and ground nut.
