Abstract:
Present study has been formulated a plans with a view to characterize physico-chemical properties of soil under three different agro-ecosystems (upland, midland and lowland) soils in Giridih district of Jharkhand. The total thirteen representative blocks were selected for soil sample collection. Hence, altogether 39 soil samples were collected for determining soil physical and chemical properties by standard protocol. Results revealed that under three different agro-ecosystems, soil of lowland, midland and upland were differs significantly in physico-chemical properties. Soil texture was recorded to be sandy loam texture (69.6 to 81.0 sand percent) for upland to sandy clay loam to loamy (60.8 to 65.0%) in medium land. The lowland soil had low bulk density as compared to upland and midland soil which, varies from 1.3 to 1.8 Mg m^-3. Highest field capacity (31.0%), PWP (18.7%) and available water (12.3%), while, lowest value for FC (15.0%), available water (6.4%) and PWP (8.6%) were observed in lowland soil of Jharkhand. The soil pH varied from near neutral pH to slightly acidic in nature under lowland to upland soil. Under lowland, midland and upland soil the lowest organic carbon content 3.2 g/Kg^-1, 2.6 g/Kg^-1 and 2.1g/Kg^-1, while, the highest value was 8.4 g/Kg^-1, 6.8 g/Kg^-1 and 6.7 g/Kg^-1 was recorded respectively. Highest value of available N (465 Kg ha^-1) and available K (272.2 Kg ha^-1) was observed from lowland, but the higher value of phosphorous (193.4 Kg ha^-1) was observed from the upland soils of Giridih districts of Jharkhand.
