OBJECTIVE FORESTRY

Detailed explanation-1: -Soil texture (such as loam, sandy loam or clay) refers to the proportion of sand, silt and clay sized particles that make up the mineral fraction of the soil. For example, light soil refers to a soil high in sand relative to clay, while heavy soils are made up largely of clay.

Detailed explanation-2: -The texture of soil is considered to be a stable property. That is, changing the texture of your soil is possible but involves considerable mechanical and financial input. One example is clay delving, where clay from the subsoil is mixed with the sandy surface soil.

Detailed explanation-3: -The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.

Detailed explanation-4: -Physical properties of soil include color, texture, structure, porosity, density, consistence, aggregate stability, and temperature. These properties affect processes such as infiltration, erosion, nutrient cycling, and biologic activity.

Detailed explanation-5: -Soil texture is the relative percentages of sand, silt, and clay particles that make up the mineral (inorganic) fraction of soil (Fig. 3). Sand particles are the largest and range from 2.0 to 0.05 mm in diameter. Silt particles are smaller, ranging from 0.05 to 0.002 mm. Clay particles are smaller than 0.002 mm.
