Question

The sequence of events occuring upon application of urea in soil are:
(A). Hydrolysis
(B). Nitrification
(C). Denitrification
(D). Leaching
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A), (B), (D), (C)
• C. (B), (A), (D), (C)
• D. (C), (B), (D), (A)

Hint:

Ammonium (\(\text{NH}_4^+\)) is held on clay exchange complexes and resists leaching. Nitrogen must first undergo nitrification to nitrate (\(\text{NO}_3^-\)) before significant leaching or denitrification can occur.
