A) The infiltration capacity of the soil
B) The prevailing wind velocity
C) The quantity of water available
D) Sprinkler irrigationAns : (a) The infiltration capacity of the soil

Explanation:

The maximum application rate by sprinklers is limited by the infiltration capacity of the soil. In this
method water is applied in form of spray, somewhat as in ordinary rain, as is done in the garden lawn sprinkling. This method is useful where
(i) Land cannot be prepared for surface methods.
(ii) Slope is excessive and topography is irregular.
(iii) Soil is erosive.
