Dear All,
Good day!
Agroecological approaches are also good for development of new fertiliser materials. Value addition of fertilizers is primarily aimed at increasing the agronomic use efficiency. Value addition of N fertilizers is achieved by taking steps to enhance the efficiency of N from the fertilizer to plants. Slow release and controlled release N fertilizers are one class of such fertilizers. There is another class of value added fertilizers known as fortified fertilizers where micronutrients are made available to the plants by incorporating with or coating the micronutrients over the fertilizer itself. E.g. zincated urea, phosphor-gypsum coated urea, sulphur coated urea etc.
On other hand, Customized fertilizers are the fertilizers, which are catering to regional soil-crop-stage specific fertilizer requirements, can be called “Customized Fertilizers”. Customised fertilizers facilitate the application of the complete range of plant nutrients in the right proportion and to suit the specific requirements of a crop in different stages of growth, and are more relevant under site specific nutrient management practices.
A good information on nature and extent of major and micronutrient deficiencies in different soils, states, agroecological zones has been generated to demarcate such areas for adopting customized fertilizer application more precisely for amelioration of such multiple deficiencies.
