DENDROLOGY

Detailed explanation-1: -Soil depth can greatly influence the types of plants that can grow in them. Deeper soils generally can provide more water and nutrients to plants than more shallow soils. Furthermore, most plants rely on soil for mechanical support and this is especially true for tall woody plants (e.g., shrubs, trees).

Detailed explanation-2: -Therefore, several measurements are required ateach field site for an estimation of the average soil depth. Parent material, Soil texture, Slope gradient, Vegetation cover, Rainfall, Land use intensity, Previous land use type, and Terraces (presence of), Water storage capacity.
