Irrigation Water Conveyance and Application Methods
Subtopic: Surface, sprinkler and micro irrigation methods
Question Statement:
Identify correct statement(s) for sprinkler irrigation:
Options:
(A) Excessive topsoil erosion is involved.
(B) Fertilizer can be applied with water.
(C) No excess cost of land preparation is involved.
(D) Evapotranspiration loss is minimum.
Official Answer Key:
B, C
Step-by-Step Solution & Explanation
Sprinkler systems allow fertigation (B) and require no special land levelling/grading (C), unlike surface irrigation. They do NOT cause excessive topsoil erosion (A) — in fact they reduce erosion compared to flood irrigation — and evaporative/wind-drift losses in sprinkler irrigation are typically higher than surface methods, so ET loss is not minimum (D) is incorrect.
