dc.description.abstract | Potassic fertilizer recommendations are made based on available (exchangeable + water soluble) K status of soils in different soil testing laboratories in India. However, recent studies employing a variety of measures of nonexchangeable K indicated a very substantial contribution of nonexchangeable fraction of soil K to crop K uptake. Present paper examines the information generated in the last 30 years on the status of nonexchangeable K in Indian soils, categorization of Indian soils based on exchangeable and nonexchangeable K fractions based on GIS mapping and K recommendations considering both the fractions of soil K. Inclusion of nonexchangeable K in the soil testing aids in predicting immediate K needs of crop plants as well as long term K needs of intensive cropping systems. Based on GIS based soil K fertility maps were prepared considering both exchangeable and nonexchangeable K, K deficient districts of the country were identified where K application is a must. Some maintenance dose of K is required in some districts where, exchangeable K is high but nonexchangeable K is low or medium. These GIS-based maps and suggested recommendations help to prioritize the K efficient zones where K application is essential and higher possibility exists for improving the K use efficiency. Special care should be taken on K fertilization on high K requirement crops like banana, sugarcane, potato | en_US |
