Major recommendations emanating from the above discussion is that there is a dearth need of developing new and improved fertilizers i. Customized fertilizers. As the micronutrients are also added with the granulated NPK fertilizer the plants can absorb the micronutrient along with macronutrient which prevents nutrient deficiency in plant.
Mixed fertilizers with micronutrients provide recommended micronutrient rates for the agricultural field at the usual fertilizer application. The farmer need not buy micronutrient separately at extra cost, thus reducing the total cost. It is found that incorporation of micronutrient with granular fertilizer at the time of manufacturing results in uniform distribution of micronutrient throughout granular NPK fertilizer.
This is because micronutrient source is in contact with the mixed fertilizer under the condition of high moisture and temperature. Micronutrient with the mixed fertilizer is one of the most convenient methods of fertilizer application and helps in more uniform distribution of nutrient with conventional application equipment. It is a very unique method developed in agriculture industry and has tremendous scope for future. How to arrive at customized fertilizers?
Scientific principles were used as an ultimate guiding factor in deciding the grades of customized fertilizers.
The fertilisers help correct the nutrient imbalance in the soil caused by prolonged inadequate and indiscriminate use of fertilisers, thus contributing to better crop productivity. The production of urea during was At present, there are 30 urea units in our country.
The total production of urea in was In , as mentioned earlier the total production was In order to create. The publisher may not agree with the independent views expressed by them.

Blanket fertilizer recommendations for different crops have caused poor nutrient supply, low nutrient use efficiency and limited crop response. Customized fertilizers may help to sustain soil health by ensuring appropriate fertilization. Hence, specific customized fertilizers should be promoted to counteract the problem of expanding multi-nutrient deficiencies in soils.
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, customized fertilizers will play a very important role. The development of site and crop specific readymade customized fertilizers based on scientific principles 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, this article discusses the manufacturing methodologies, eligibility criteria, success in Indian fertilizer industry, adoption of fertilizer recommendations and problems in marketing of customized fertilizer.
