Vegetation influences the kind of soil developed, in that plants vary in types of root system, size, and nutrient composition. Soils formed under trees are greatly different from soils formed under grass even though other soil
Soils – Fundamental Concepts

Soil Texture - Cornell University
nmsp.cals.cornell.eduNew York soils are divided into five different mineral soil management groups (I through V) based on soil texture and parent material from which the soil was formed. Group I soils are medium- to fine-textured. Group II soils are moderately fine- to medium-textured. Group III soils range from medium-textured to moderately-coarse soils.
