OBJECTIVE FORESTRY

Detailed explanation-1: -Loamy soils are known to have a higher content of humus than sandy soil but lower content of humus than clayey soil.

Detailed explanation-2: -The Laterite soil develops in the areas with high temperature and heavy rainfall. This soil is highly leached due to heavy rains. The humus content of laterite soil is low as most of the microorganisms, particularly the decomposers, like bacteria, get destroyed due to high temperature.

Detailed explanation-3: -Loamy soil is composed of a mixture of sand, clay and humus. Loamy soil contains different sizes of particles.

Detailed explanation-4: -’A’ horizon is the topmost layer of soil profile. The maximum content of humus is found in this layer. The humus content decreases as we move deeper. This is because most of the living organisms live in the topmost layer of soil i.e. ‘A’ horizon.
