'Study of correlation between S fractions with soil properties in Soils of Tuljapur tahsil of Osmanabad District'

摘要

The present investigation was carried out to study assessment of different nitrogen and sulphur forms in soils of Tuljapur tahsil of Osmanabad district. For this purpose 180 representative soil samples were collected from 30 villages of Tuljapur tahsil. The collected soil samples were grouped into three orders viz. Vertisols, Inceptisols and Entisols. Out of the total surveyed soil samples, 34 per cent samples were grouped under Vertisols while, 47per cent and 19 per cent samples were grouped under Inceptisols and Entisols, respectively and orderwise anaysis was carried out.In chemical analysis, the soils under study area were alkaline in reaction, safe in limit of electrical conductivity and moderately calcareous to calcareous in nature. The organic carbon content in soils was found low to medium.The soils were found to be low in all the fractions ofS viz. total S, available S, organic S, water soluble S and non-sulphate S.The pH and CaC03 showed negative and significantly correlated with all thefractions of sulphur in Inceptisols and Entisols. Whereas, organic carbon showed positive and significant correlation with different fractions of sulphur in ail soil orders. However, electrical conductivity showed negative and significant correlation with all the fractions ofS except available S in Vertisols and EC did not showed any relation with S fractions in Inceptisols and Entisols under study.
