Soil samples were collected from two depths (0–15 and 15–30 cm) and analysed for soil fertility parameters namely: available N, P, K and S. The results indicated that the different cropping systems had positive influence on improving the nutrient status (i.e., available N, P and K) significantly over the initial soil values (N: 112.20, P: 23.40 and K: 170.30 kg ha -1 , respectively). Interestingly, it was noticed that improved availability of nutrients (N, P, K and S) was more profound in the upper soil layer (0– 15 cm) compared to lower depth (15–30 cm) in all the cropping systems (CS). The CS: Bt cotton + Greengram – Groundnut had recorded high nitrogen (N=221.60 kg - 1), CS: Fodder maize – Lucerne recorded high in available P (P=49.13 kg -1 ) and CS: Fodder sorghum + Fodder cowpea – Horsegram – Sunhemp recorded high in K and S (K=208.10 kg -1 , S= 172.0 kg S ha -1 ) after kharif Original Research Article
