Clay soil requires herbicide dose than sandy one

A. More

B. Less

C. Equal

D. Not dependent upon texture

Answer: Option A

Solution(By Examveda Team)

Clay soil requires more herbicide dose than sandy soil. Clay particles are negatively charged and have a large surface area. Therefore the soils which have a high content of clay can absorb or tie up with the molecules of herbicides. While the percolation rate of sandy soil is more it absorbs the moisture and chemicals in the least amounts.
