Why does clay soil have a very good water holding capacity?

The large surface area of the clay particles allows them to hold a greater quantity of water. Thus, the water holding capacity is the highest in clayey soil due to the large surface area as well as the tightly packed particles that restrict the water from percolating.

Why does sandy soil not hold water?

Sandy soil: It has larger particles with larger spaces between them, and they are filled with air. So it is called as well-aerated soils. Due to the large spaces, water can easily penetrate through the particles of sand. So, it cannot hold water.

Which absorbs more water sandy or clay?

Answer: Clayey soil absorbs more water than sandy soil and allows less water to percolate.

Does clay soil absorb water?

Clay Soil, because of its small particles and very tiny pore space, absorbs water at a rate of less than 1/4 inch per hour. A combination of sand, silt, and clay particles, this soil absorbs water readily and is able to store it for use by plants.

Why clay soil has less air holding capacity as compared to sandy soil?

Soil contains air Sand particles cannot fit closely together, so there is large space between sand particles. The large space between sand particles is filled with air. But clay particles pack tightly together leaving little space for air. So, clayey soil provides much less air to the plant root which grows in it.

Why sand has less water holding capacity?

The larger the surface area the easier it is for the soil to hold onto water so it has a higher water holding capacity. Sand in contrast has large particle sizes which results in smaller surface area. The water holding capacity for sand is low.

Which clay holds more water?

Clay soil
Clay soil has small, fine particles, which is why it retains the most amount of water. Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water. Silt and loam, with medium-size particles, retain a moderate amount of water.

How does clay soil absorb water?

Clay Soil, because of its small particles and very tiny pore space, absorbs water at a rate of less than 1/4 inch per hour. Water, literally runs off this type of soil. Yet, clay soil can hold large amounts of water when it is absorbed. However, some of the water is held so tightly that plants cannot use it.
