The study was conducted to know the soil fertility status of different cropping systems in hill zone acid soils of Karnataka. In each cropping systems, samples were collected from two depths (0-15 cm and 15-30 cm) at 20 locations randomly. Soil characterization revealed that soils were slightly acidic to moderately acidic in range with low soluble salts. Surface soils under paddy cropping system recorded higher exchangeable Al3+ and exchangeable acidity compared to coffee and areca cropping system. Soils are medium in available N and P status but high in available K, Ca, Mg and S status in all cropping systems. Amount of DTPA- extractable Fe, Mn, Zn and Cu were higher in coffee and areca systems compared to paddy system. The content of available nutrients decreased with depth in all cropping systems. Available nutrients status was lower in paddy system compared to other two systems.
