Deficiency of essential micronutrients is a hot burning issue
in developing countries such as Zn, Fe, that lead to the improperA1   growth, and development.
The population of the world grown day by day and expected to be 10 million in
2050 (United Nations, 2013) .Food security is a
major challenge in the 21st century due to the limited avaibility of
the water recourses , fertilize land and the declining in the micronutrients in
plants ( Blindauer et al., 2010). One
important feature that effects both plant growth as well as the nutritional
value of field crops are micronutrients (Schmid
et al., 2010). Low levels of accessible mineral supplements in soil, improper
supplement administration of the minerals, with the absence of the plants genotypes
having lack of tolerance to deficiency of nutrient are the major cause of food
security and the deficiency of essential micro nutrients in peoples. The fact
that the 60% cultivated soil have the problem of nutrients deficiency.

human diet in numerous ranges of the world does exclude the basic metal
supplement necessities, causing from minor immunological reforms to death (Akkermans
et al., 2016). Deficiency of the
nutrients occurs in all over the world (Hodson & Donner, 2013).The FAO (2011). Considers that almost a billion
people are under-nourished, most in sub-Saharan Africa (239?million) and Asia
(578?million). The yield is low in these areas due to their soil and deficiency
of micronutrients such as Zn, Mn, Fe, these areas required the improvement of nutrition
uptake and the fertilizers. (Gregory et al., 2014). 25-30% agriculture land have small avaibility
of Fe, Zn, and Cu (Broadley et al., 2007; White & Greenwood., 2013).

Many chronic disease that occur in societies due to under nourishment
related to the essential micronutrients .But this is masked by improving the
soil and the micronutrients uptake system (Graham et al., 2012).The deficiency of nutrient cannot only achieved only by the
fertilizers because 20-80% of nutrients present in fertilizers are lost in the
environment due to the complex chemistry of soil that reduce the nutrients (Sebilo et al., 2013).

There is no doubt that the production
of fertilizers with the improvement of the nutrients uptake system could reduce
the loss of nutrient and  use of
fertilizers (Withers et al.,2014 ) .In the 21 Century, plant nutrition research
become a major area in meeting the food production with the increase in
micronutrient. Developing the crop varieties, in
which uptake of metals have been improved (Eggert
and von Wiren., 2013)
