OBJECTIVE FORESTRY

Detailed explanation-1: -Deeper soils generally can provide more water and nutrients to plants than more shallow soils. Furthermore, most plants rely on soil for mechanical support and this is especially true for tall woody plants (e.g., shrubs, trees).

Detailed explanation-2: -Clayey soil is composed of very fine mineral particles with high water holding capacity. Due to its good water holding capacity, clayey soil is used for growing crops in fields.

Detailed explanation-3: -How much water a soil can hold against gravity is very important for plant growth because the water retained in the soil can compensate for a lack of precipitation in dry years, but not all of the water held by soil is available for plant growth.

Detailed explanation-4: -Loamy soil is best for plant growth as it has high water retention capacity thus it retains water for long and also retains the nutrients which is required for plant growth.
