Increased costs as well as increased awareness of the impact of fertilizer leaching on the environment have increased interest in use of controlled release fertilizer to increase the nutrient uptake efficiency and reduced the nutrient leaching potential. The application cost of fertilizer also reduced considerably.

Do you think controlled release fertilizer has a future for the fertilizer industries and agriculture?

In my view, in the next decade or so controlled fertilizers will take over fertilizers like pilled urea. They are definitely superior to the ordinary urea in terms of increasing yield of crops as well as fertilizer nitrogen use efficiency (and as a consequence reduced loss of N to the environment). At present, the major hurdle in the extensive use of controlled-release fertilizers is their cost vis-a-vis highly subsidized urea or neem coated urea (in India). If we look at the trend in the price of these fertilizers, it is rapidly decreasing with the advancement in coating technologies. We started with sulphur as a coating and now we have polymer-coated urea. Things are changing very fast and I am of the belief that not very far in the future most of the fertilizer N used in crop production will be controlled-release urea.

It might be, but not at all for all the time. There will be definitely needed of controlled release fertilizers in future agriculture, but the necessity of quick released fertilizers should have the great demand for as usual growth and development of plants forever. For instance, top dressing is a universal practice for shallow rooted and short duration crops/plants for which some fertilizers like urea is applied to release N quickly as required by crops.

Undouble, it is very important as proven by fertigation under protected cultivation. Replication of same in open fields with enhanced efficiency and productivity is practiced by innovative farmers in vegetable crops. Preparation of Nano fertilizers is ahead for the same purpose.

Without any doubt , it has a bright future .And more so in horticultural crops having longer duration of crop maturity than annual crops.
