Description Soil health diagnosis in nearly 100,000 farmers’ fields under ‘Bhoochetana’ initiative in Karnataka showed widespread soil degradation.
Soil mappingbased
fertilizer management was an effective entrypoint
intervention to take most farmers onboard
to initiate the
process of upgrading agriculture. Soils of the farmers’ fields showed low levels of microand
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 mappingbased
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 testbased
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 risktaking
ability of farmers to invest in technologies based on
use of soil testing and use of improved cultivars of crops. The adoption of simple knowledgebased
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 knowledgebased
entry point interventions like soil mapping and improved varieties targeted
at providing simple solutions are the best options for quick benefits and rapportbuilding with the majority farmers to initiate a collective
action for technological upgradation of dry land agriculture.
