A.
a-2, b-1, c-3, d-4
Answer
B.
a-1, b-4, c-2, d-3
C.
a-2, b-3, c-4, d-1
D.
a-4, b-1, c-2, d-3

Answer: Option A

Solution

Answer: Option A
Solution:
a. N content in Anhydrous ammonia is 82%. Anhydrous ammonia, NH3, is typically among the least expensive sources of nitrogen and contains 82 percent nitrogen by weight, the highest of all available sources.
b. N content in Ammonium Phosphate is 16%. Ammonium phosphate is an inorganic compound with the formula (NH4)3PO4. It is the ammonium salt of orthophosphoric acid.
c. N content in Di-ammonium phosphate is 18 - 21%. DAP (NH4)2HPO4: Fertilizer grade DAP Contains 18% Nitrogen and 46% Phosphorus (P2O5). DAP is manufactured by reacting Ammonia with Phosphoric acid under controlled conditions in fertilizer plants.
d. N content in Ammonium chloride is 25%. Ammonium chloride, a by-product of sodium bicarbonate production, contains 25 and 65% N and chlorine, respectively, and can be used as a nitrogen fertilization source in crops.
