Customized Fertilizers: Marker in Fertilizer Revolution

摘要

In India, among the nutrients, NPK remain the major ones for increased and sustained productivity. However, the development of high yielding systems will likely exacerbate the problem of secondary and micronutrient deficiencies, not only because larger amounts are removed, but also because the application of large amounts of N, P and K to achieve higher yield targets. As a result in the intensive systems there is every possibility to build up of negative balance and deficiency of secondary and micronutrients. To attain high future targets, balanced fertilization, site-specific nutrient management and customized fertilizers will play a very important role. The development of site and crop specific readymade customized fertilizers based on scientificprinciples may prove to be more effective to meet the plant requirement and enhance nutrient use efficiency. Such an approach is also likely to boost crop yields and arrest soil fertility decline in a long-run. Thus, the present article focuses towards the different aspects of customized fertilizers related to their need, production, norms and prospects in a long run.
