Soil Mottling generally indicates poor aeration and impeded drainage.
-
True
-
False
Correct Answer
A. TrueExplanation
Soil mottling refers to the presence of contrasting colors or spots in the soil, which can indicate poor aeration and drainage. When soil is poorly aerated, it means that there is not enough oxygen available for the roots of plants to thrive. Additionally, if drainage is impeded, excess water can accumulate in the soil, leading to waterlogged conditions that are not conducive to healthy plant growth. Therefore, the statement that soil mottling generally indicates poor aeration and impeded drainage is true.Rate this question:
