The distribution of desert shrubs varies with soil depth, texture, and elevation.

Gradients of soil moisture, soil depth, elevation and aspect control the distribution of many trees, shrubs and herbaceous species.

Terracing allowed for an increased soil depth and impeded soil erosion.

Soil depth and topographic position can influence yields.

Where irrigation water and soil depth are sufficient, sugar beets, potatoes, alfalfa, small grains, and vegetables are grown.
