Abstract:
Investigating the fertility status of organic and conventional farming systems soils is required to underpin future recommendations. A survey was carried out in 0-30 cm depth in organic farming and conventional farming farmer fields of Sira taluk (Tumakuru Dist.), Hiriyur taluk (Chitradurga Dist.) and Jagalur taluk (Davanagere Dist.) in the central dry zone of Karnataka. Soil pH and primary nutrients (N, P2O5 and K2O) were registered as higher in conventional farming system (7.40, 353.02, 50.05 and 360.37) than in organic farming system (7.19, 319.69, 47.88 and 342.99). In contrast, organic farming was highlighted (4.68, 2.99 and 25.47) than conventional farming system (3.97, 1.73 and 19.24) in case of secondary nutrients (Ca, Mg and S). A major part of the primary and secondary nutrients in this zone were deficient.
