Abstract:
A study was undertaken to evaluate seven soil series belonging to Malli-1 micro watershed of Yedrami taluka, Kalaburagi district in North Eastern Dry Zone of Karnataka for sustainable land use planning. Seven soil series were tentatively identified and mapped into eight mapping units using GIS technique. Weighted mean of each soil property was calculated and soil-site characteristics of different soil mapping units were obtained. These soil-site characteristics data used to evaluate the land capability classification and soil-site suitability. Eight mapping units were grouped into land capability class III, IV and VI with limitations of erosion, texture and physico-chemical properties. Generally, Margutti (P-1) & (P-2) series were moderately (S2) suitable for sorghum, marginally (S3) suitable for greengram and currently not suitable (N1) for all other crops. Bhimanahalli and Gutti series of the study area was moderately (S2) and marginally suitable (S3) for pulses and cereals crops and currently not suitable (N1) for all other horticultural crops. Novinihala series was moderately (S2) and marginally suitable (S3) for pulses and cereals crops except bengalgram and currently not suitable (N1) for all horticultural crops. Rajhnal, Mahagoan and Gutti series were moderately (S2) suitable for greengram and sorghum, marginally (S3) suitable for pigeonpea, bengalgram, guava, sapota and currently not suitable (N1) for mango.
