| Abstract: | IDC, International Crops Research Institute for the Semi-Arid Tropics, Patancheru 502 324, India Soil health diagnosis in nearly 100,000 farmers' fields under 'Bhoochetana' initiative in Karnataka showed widespread soil degradation. Soil mapping-based fertilizer management was an effective entry-point intervention to take most farmers on-board to initiate the process of upgrading agriculture. Soils of the farmers' fields showed low levels of micro- and secondary nutrients such as zinc (Zn) (55%), boron (B) (62%) and sulphur (S) (52%) in addition to that of phosphorus (P) (41%), potassium (K) (23%) and soil organic carbon (C) (52%). Soil mapping-based fertilizer management recorded significant productivity benefits that varied from 25% to 47% in cereals, 28% to 37% in pulses and 22% to 48% in oilseed crops. In terms of economics, a rupee spent on soil test-based fertility management brought returns of Rs 3 to Rs 15. Similarly, the participatory trials showed that the use of high yielding varieties of sorghum, pearl millet, finger millet, groundnut, soybean, castor, pigeonpea and chickpea enhanced productivity by 30% to 123%. The tangible benefits through soil mapping and variety based interventions have enhanced the risk-taking ability of farmers to invest in technologies based on use of soil testing and use of improved cultivars of crops. The adoption of simple knowledge-based technologies as entry point interventions along with policy reorientation to ensure knowledge sharing and availability of needed inputs at village level, enabled in a period of four years (2009--2013) to outreach more than 5 million families in Karnataka to transfer improved technologies in more than 7 million ha area. The study indicates that knowledge-based entry point interventions like soil mapping and improved varieties targeted at providing simple solutions are the best options for quick benefits and rapport-building with the majority farmers to initiate a collective action for technological upgradation of dry land agriculture.
