Soil Geography

From Introduction to Soil Science by Amber Anderson and Rivka Fidel

Concepts

1. Spatial Variability

   "Different soils have different capabilities, so land use and management need to account for where those soils occur. Soil varies vertically within profiles and laterally across landscapes because of

2. Slope Influence

   "Slope affects water movement, erosion, infiltration, and sediment accumulation. Steep slopes increase water energy and erosion, while gentle or level areas slow water and encourage accumulation. Summ

3. Dynamic Soil

   "Soil survey maps commonly emphasize static properties that change slowly and represent natural soil capability. Dynamic properties such as nitrate can change through plant uptake, denitrification, le
