OBJECTIVE FORESTRY

Detailed explanation-1: -Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water.

Detailed explanation-2: -Silt, which is known to have much smaller particles compared to sandy soil and is made up of rock and other mineral particles, which are smaller than sand and larger than clay. It is the smooth and fine quality of the soil that holds water better than sand.

Detailed explanation-3: -Clay particles have the ability to physically and chemically “hold” water molecules to the particle more tightly than sands or silts.

Detailed explanation-4: -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.
