AGS 106 - Soils Lab

Description: Hands-on evaluation of factors important in soil sciences. Emphasis on soil remediation, protection and fertility through understanding of physical, chemical and biological properties of soil affecting plant growth, the environment and other land uses. Includes soils in a world ecosystem with focus on Arizona soils. Concentration on soil factors for agriculture, viticulture and environmental sciences.
