Texas FFA Nursery Landscape Practice Exam

Which soil type typically has a higher absorption time for irrigation water?

1. Sandy soils

2. Loamy soils

3. Clay soils

4. Silty soils

The correct answer is: Clay soils

Clay soils are known for their smaller particle size and compact structure, which results in a higher absorption time for irrigation water. This means that water moves more slowly through clay compared to other soil types. The tightly packed particles create a dense environment that restricts water movement, leading to slower infiltration rates. Because of this, irrigation on clay soils requires careful management to ensure that water reaches the root zone without causing runoff or pooling. Understanding the characteristics of clay soils is crucial for effective landscape management and irrigation practices, as it influences both water retention and the overall health of plants.
