OBJECTIVE FORESTRY

Detailed explanation-1: -Sandy soils have rather large particles and large pore spaces (macro pores). Clay soils have very tiny particles with very small pore spaces (micro pores), but because there are many times more pore spaces, clay soils have greater total pore space than sandy soils.

Detailed explanation-2: -Sandy soils have relatively high bulk density because they have less total pore space than silty or clayey soils (not applicable to red clayey soils and volcanic ash soils). Bulk density typically increases as soil depth increases.

Detailed explanation-3: -Sandy soils are often known as light soils due to their high proportion of sand and little clay (clay weighs more than sand).
