OBJECTIVE FORESTRY

Detailed explanation-1: -Soil organic matter Decomposition is a biological process that includes the physical breakdown and biochemical transformation of complex organic molecules of dead material into simpler organic and inorganic molecules (Juma, 1998). Decomposition of organic matter is largely a biological process that occurs naturally.

Detailed explanation-2: -Soil components are transformed by chemical and biological reaction. Organic compounds decay, some minerals dissolve, other minerals precipitate. These transformation result in the development of soil structure, and in changes in color, relative to the parent material.

Detailed explanation-3: -Nutrient transformation a range of soil biological processes which lead to changes in the chemical or physical status of nutrient resources (excluding assimilation). These processes are: mineralisation, N transformations, S transformations and fragmentation.

Detailed explanation-4: -Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up.
