Important plant nutrient next to nitrogen is phosphorus (P).
Phosphorus deficiency is widely noticed in soils with low pH or
high concentrations of aluminium and iron. It has been found that
nearly 30-40% of the cultivated lands in the world is challenged
by P deficiency. The extent of P deficiency is found to be high in
tropical and subtropical areas. In India, the extent of P deficiency is 49.3%. Moreover, P fertilizers are found to be costly as the
raw material is imported from other countries. The raw material
is rock phosphate, Yet, high grade rock phosphate is required for
manufacture of P fertilizers. According to FAO, it is estimated that
about 260 million tonnes (Mt) of RP deposits are available in India
and only a fraction of it (about 5.27 Mt) meets the specification of
the fertilizer industry because of their low P content (low-grade).
Thus, only 10% of native available RP is suitable to produce P
fertilizer in India. Recently, ministry of chemicals and fertilizers
reported that India cam become Aatmanirbhar in phosphatic fertilizers. The Government of India (GOI) has taken an action plan
to make use of indigenous rock phosphate for manufacturing P
fertilizers.
