Efficient fertilizers and fertilization methods have become the only answer to the ever-growing demand for farm produce. Modern agriculture must supply crops with optimal rates of nutrients throughout the growth cycle in the most efficient manner and without degrading soil and water resources. This can be achieved through adoption of modern and precision practices in terms of nutrient management with Specialty Fertilizers.

Specialty Fertilizers (SF) are fully water-soluble solid fertilizers having high content of primary nutrients with low salt index. They may or may not have Secondary/micro-nutrients. These water-soluble fertilizers can be advantageously utilized for foliar feeding and Nutrigation/Fertigation, thus helping in precision agriculture. The simultaneous delivery of water and fertilizers to the crop through the irrigation system ensures that plant nutrients are directed to the active root zone. Nutrigation/Fertigation amplifies the nutritional and environmental benefits of this technique by using pure plant nutrients exclusively. A well-balanced Nutrigation program will satisfy the exact needs of the plant as they change along the season.

Specialty fertilizers require distinct attention as it is relatively unknown to Indian farmers and comes with a new concept of precision agriculture. The consumption of specialty fertilizers is growing and indicating the improved acceptance of the concept and products. The consumption of specialty fertilizer is expected to grow in coming years in view of greater commercialization of agriculture, mandatory provision of fertilizer tank in government projects of Micro Irrigation systems along with growing concern towards quality of output and need to achieve higher productivity from every unit of land.
