OAR@ICRISATSoil Fertility Atlas for Karnataka, IndiaS PWaniauthorK LSahrawatauthorK VSarveshauthorMBaburaoauthorKKrishnappaauthorOur research during the last decade showed that soil testing is an effective tool for diagnosing nutrient problems in farmers' fields. Soil test-based nutrient management allows a judicious use of fertilizers supplying various nutrient elements. This Atlas comprises of results from Bhoochetan Mission Project Under which a large-scale sampling was undertaken on farmers' fields in all the district of Karnataka. Bhoochetana is a mission project for enchancing agricultural productivity of rain-fed systems in the state of Karnataka by adopting science-led approach with technical backstopping from ICRISAT-led consortium. The recommendations on nutrient applications are made by using critical limits in the soil for major, secondary and micronutrients. The soil test results are categorised as sufficient (Soil test value above the critical limit of an element) or deficient (Soil test value below the critical limit).Soil Science2011International Crops Research Institute for the Semi-Arid TropicsMonograph
