| dc.description.abstract | Surface land characters (slope, soil texture, degree of erosion and surface gravelliness) were captured by physical traversing and also by IRS P6 LISS-IV data interpretation. Seven typical pedons, P1, P2, P3, P4, P5, P6 and P7 in the Asoti-4 micro-watershed were studied for their morphological and physico-chemical properties. Further, land was evaluated for capability, irrigability, soil suitability for locally preferred crops and mapped using GIS software. The eight mapping units; MU1, MU2, MU3, MU4, MU5, MU6, MU7 and MU8 were derived based on surface topographic variations and morphological descriptions of seven pedons of the watershed. The soils of these pedons were classified taxonomically into four series and mapped. The AST-1 (P1, P2 and P6), MNS-1 (P3 and P4), and MNS-3 series (P7) were grouped under Vertisol whereas, MNS-2 series (P5) was grouped under Inceptisol. The soils were very deep, very dark gray (10 YR 3/1) to very dark brown (10 YR 2/2) in colour, clayey in texture, moderate medium sub angular blocky to weak medium angular blocky in structure, slightly hard to hard in consistency, very sticky and plastic, low in bulk density, very high in WHC, exhibited deep cracks. Soils exhibited moderate alkaline to strongly alkaline reaction, non saline, low to medium OC content, very high CEC (more than 55 cmol (p+) kg-1), high base saturation and moderate to high lime content. The land capability class of study area was moderately good land (IIItsf) and irrigable soil class was suitable (IIItws). The Asoti-4 micro-watershed area was moderately suitable (S2) for sorghum and pomegranate, marginally suitable (S3) for chilli and most of the other agricultural crops except wheat. For majority of horticulture crops, the area was not suitable (N) for cultivation. The fertility analysis revealed that they were low, low to medium, medium to high, sufficient and low to medium in available N, P2O5, K2O, micronutrient cations and boron, respectively. | en_US |
