How many inches does one inch of water permeate a sandy soil?

In sandy soils, water drainage occurs quite rapidly due to the large particle size and the spaces between those particles, which allow water to move through easily. Generally, one inch of water can infiltrate a sandy soil to a depth of approximately 12 inches. This characteristic makes sandy soils well-draining, but it also means they can dry out quickly, requiring more frequent irrigation.

The measurement of 12 inches reflects the typical response of sandy soil to irrigation or rainfall, providing a balance between quick drainage and the ability to retain moisture for plant roots. Understanding this concept is crucial for proper water management practices in horticulture, especially when choosing appropriate irrigation strategies for different soil types.
