Sandy soils possess greater drouth potential compared to clay loam soils. This is primarily because sandy soils have larger texture particles, which leads to larger pore spaces. While this structure allows for better drainage, it also means that sandy soils cannot retain moisture as effectively as finer-textured soils such as clay loams. Consequently, sandy soils can dry out more quickly during periods of limited rainfall, leading to increased drought stress on plants. In terms of impact on yield potential, higher drouth potential can severely constrain growth and crop yields, especially during dry conditions.

In contrast, clay loam soils, which have a finer texture and smaller pores, can hold more moisture due to their higher water retention capabilities. They also typically have better nutrient-holding capacity and organic matter content, leading to enhanced soil structure and fertility. While these factors contribute positively to plant health and yield, they are not related to drouth potential, which is specifically a concern with sandy soils.
