Pakistan is an agricultural economy country that relies on fertilizers. Among these fertilizers, phosphatic fertilizers play a vital role in plant growth and soil fertility. The efficiency of fertilizers depends on the quality of rock composition. Assessment of rock phosphate from different areas of hazara division of Pakistan is done. Analyses showed that these sources contained P 2 O 5 from 19to 30% and Fe 2 O 3 from 0.80 to 2.51%. Deposits of Qalandar Abad contained high Fe 2 O 3 contents i. e 2.36%. Whereas, deposits of Lagar Ban contains only 0.9 % Fe 2 O 3 . Deposits of Tornai – Mangal contained Fe 2 O 3 about 1.25 % and in the other hand contain P 2 O 5 about 30 % and are ideal for fertilizers. Deposits of Kakool and Tornai are highly suitable for current fertilizer processes. |
