Abstract: Chemical properties of some irrigated and rainfed cotton growing surface soils (0-22.5 cm) from 11 talukas of South Gujarat comprising Bharuch, Surat and Narmada districts were investigated. pH, EC, CEC, ESP, soil organic C and inorganic carbon were determined from total 110 nos. samples for proper management of these soils and achieving higher cotton yield. The results revealed that above parameters chronologically ranged from 6.5-8.8, 0.62-2.89 dS m-1, 35.9-63.8 cmol (p+) kg-1, 3.43-10.18, 2.70-9.41 g kg-1 and 0.95-14.40 g kg-1, respectively in irrigated soils, while the corresponding values were 6.7-9.5, 0.21-2.59 dS m-1, 35.9-55.7 cmol (p+) kg-1, 4.52-11.56, 2.85-7.90 g kg-1 and 1.58-19.40 g kg-1, respectively, in rainfed soils. However, the mean values of the above parameters were 7.8, 1.70, 51.0, 6.55, 6.19 and 4.93, respectively in irrigated soils and 8.2, 1.41, 46.6, 7.94, 4.83 and 8.79 respectively in rainfed soils. Major irrigated soils (63.7%) belonged to ‘neutral’ to ‘mild alkaline’ in reaction while, major rainfed soils (67.4%) came under ‘mild alkaline’ to ‘very strongly alkaline’ in reaction. Salinity of both irrigated and rainfed soils were ‘low’. For CEC > ‘40’ cmol (p)+ kg-1, > 92.8 and > 85.5 per cent soils, for ‘5 to 15’ ESP, 29.1 and 61.8 per cent soils, for ‘low’ organic carbon, 20 and 51 per cent soils and for ‘high to very high’ SIC, 20 and 51 per cent soils respectively were responsible in irrigated and rainfed situations, respectively.
