High fertilizer nitrogen use efficiency means more of applied N is being utilized by the crops to produce high yield levels. Therefore less N is left for getting lost from the soil-plant system for degradation of the environment.

Can high fertilizer nitrogen use efficiency ensure both food and environmental security?

Nitrogen is the universally deficient macro soil nutrient, that’s basic. If NUE is increased over Time-dimension( Ex- slow release ‘N’ fertilizer) then it is well n good. So my view point is Its not the debate about good or bad but it is debate over “HOW we are going to increase NUE, the method”?

First the soil test is very important. After that on the basis of soil test results you can choose appropriate fertilizers. Anything in a very high or in low amount is harmful to the soil and environment as well. So, use only recommended dose and choose your fertilizers on the basis of soil testing.

You cannot use a unformed code for every situation – as mentioned above, soil formation and nutrient characteristics depend basically on geology and subsequent abuse. One has to get the soil test done before deciding on the nitrogen requirement. In fact we have already converted vast areas of forest into agricultural land to meet the food security. Any further damage to the remaining forests is not advisable. What we could concentrate is to strengthen the existing to ensure better yield with quality seeds.

These are major challenges of how to simultaneously ensure global food security along with high nitrogen use efficiency (NUE) and protect the environment have received increasing attention. However, the prevailing agricultural pattern still considers high yield and reducing environmental impacts to be in conflict with one another. (i) To develop efficient root-zone nutrient management to significantly increase NUE, (ii) integrated nutrient management to increase both yield and NUE by 15%—20% and (iii) integrated soil-crop system management (crop rotation with legumes or pulses) to increase yield and NUE by 30%—50% simultaneously. These advances can thus be considered an effective agricultural paradigm to ensure food security while increasing NUE and improving environmental quality.
