Question

Soil cannot retain much water.

Answer 1

Explanation:

• Sandy soil has a larger particle size; it cannot hold much water and needs frequent smaller doses of water. Silt has smaller particles; its water-holding capacity is ideal for most plants.

Answer 2

[tex][/tex] Soil cannot retain much water.

Water-holding capacity is controlled primarily by soil texture and organic matter. Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity. The table illustrates water-holding-capacity differences as influenced by texture. Organic matter percentage also influences water-holding capacity. As the percentage increases, the water-holding capacity increases because of the affinity organic matter has for water.
