Sandy soils are best for drainage due to their larger particle size and structure, which allows for greater pore space between the particles. This increased space facilitates the movement of water through the soil, preventing water from pooling and ensuring that excess moisture can move downward effectively. Sandy soils can dry out quickly after rain or irrigation, making them ideal for certain crops that require well-drained conditions and preventing issues such as root rot that can occur in poorly drained soils.

In contrast, clay soils have very small particles packed closely together, which limits drainage and can lead to water retention. Silt soils, while somewhat more adaptable, also retain more moisture due to their finer particles compared to sand. Loamy soils, though they possess a combination of sand, silt, and clay that provides a balance of drainage and nutrient retention, do not drain as quickly as sandy soils. This makes sandy soils the optimal choice when the primary concern is drainage.
