Which soil is typically associated with low water retention?

Sandy soils are characterized by their larger particle size and gritty texture, which creates larger pore spaces between the grains. This structure allows water to rapidly drain through the soil, leading to low water retention capability. When sandy soils are moist, they do not hold onto water for long periods, which can be both an advantage and a disadvantage depending on the plants being grown. Plants that require well-drained conditions may thrive in sandy soils, but those that need consistent moisture can struggle.

In contrast, clay soils have very fine particles that create smaller pore spaces. This compact structure allows clay soils to retain significant amounts of water, making them capable of holding moisture effectively. Silt soils fall somewhere between clay and sand in terms of particle size and have moderate water retention, while alluvial soils, which are formed by the deposition of sediments from rivers and streams, often consist of a mix of soil types but typically have good fertility and water retention due to their higher organic matter content. Thus, sandy soils stand out for their low water retention capabilities compared to the other types listed.
