Trees require soil for support, water, and nutrients. Soil quality is a concern for arborists and urban foresters because it directly influences tree and shrub establishment, stability, growth, health, and longevity. High-quality soils enable trees to grow and thrive, while poor-quality soils hinder establishment, slow growth, and shorten longevity. In order to recommend soil modifications, develop management or soil conservation recommendations, and provide information to match plant species with site conditions, it is important for arborists to perform a soil assessment.
