OBJECTIVE FORESTRY

Detailed explanation-1: -Water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of sandy soil, so clays generally hold more water. Sands provide easier passage or transmission of water through the profile.

Detailed explanation-2: -Clayey soil contains small sized particles, sandy contains large particles while loamy is the mixture of both small and large particles in equal proportions. Thus, the water holding capacity is highest in the clayey soil.

Detailed explanation-3: -Answer: False. Water logging occurs in clayey soil, which absorbs and retains a lot of water. Sandy soil cannot absorb much water because of the large spaces between the soil particles.

Detailed explanation-4: -Clay soils retain more water and nutrients than sand, but there is little percolation of the water and less oxygen for the plant due to smaller pore sizes than those of coarser textures.

Detailed explanation-5: -Sandy soil will absorb less water and allows more water to percolate. Clayey soil will absorb more water but allow less water to percolate.
