Micronutrients and the agroecology of tropical and Mediterranean regions, possibility of identifying areas of potential micronutrient problems on the basis of existing information on soils and climate is still remote. Such areas, therefore, are identified through site characterization based on surveys of micronutrient deficiency symptoms, extensive micronutrient soil testing, or selective micronutrient trials.

Sources and production of micronutrient fertilizers,very scarce metal Mo. In at least one of their valence states, these elements all form compounds that are fairly soluble under conditions at the earth’s surface and are designated by geologists as mobile. Mobile elements often move from the site of the source mineral as a result of weathering.

Micronutrient needs of tropical food crops,nse to this uptake, and the way in which the tropical climate and crop varieties might affect the amounts of micronutrients needed. We will also discuss trends in crop management and yield levels and how these factors affect micronutrient needs.
