Concept: Sprinkler irrigation distributes water through the air, so weather conditions can affect its efficiency.
Explanation: In a sprinkler system, water is sprayed into the air like rain.
When wind is strong, it blows the water droplets sideways.
This causes uneven water distribution across the field.
Some areas receive too much water, while others receive too little.
Therefore, high wind velocity is a major practical limitation.
The other options are less accurate: soluble fertilizers and herbicides can often be applied through sprinklers, and the system can be used in high evapotranspiration areas if water supply is adequate.
Answer: D. high wind velocity could prevent uniform distribution of irrigation.
