Soil is the reservoir of macro and micro nutrients with the inception of commercial farming the emphasis is given to production without taking care of soil health and eventually soil health deteriorates and production falls. One of the very important components of soil health remained neglected and now reached to the threatening level. Management of balanced nutrients has become of vital importance. Without minimizing the importance of macronutrients in quadrupling the fruit production in the world during the last 50 years, it can be stated that micronutrients are going to play a major productive and qualitative role in bringing stability and sustainability in the production system during the next few decades, particularly in respect of tropical and sub-tropical fruit crops.
Key words: Micronutrient, tropical, sub-tropical.
