Purpose: To look for a connection between soil pH and vegetation.
+To see how soil pH changes from one horizon to the next.
Basic Procedure: At multiple sites, record nearby vegetation, then dig soil pits to see the horizons, taking samples from each horizon. Test the pH of each soil sample.
A Little Background: A soil horizon is a layer of soil.
The three top layers are:
- O-Horizon: Organic layer rich in decomposing matter and nutrients.
- A-Horizon: Nutritious soil beneath the O-Horizon AKA Topsoil, usually home to deeper roots of trees and shrubs.
- B-Horizon: Hard layer of clay and rock, with many minerals that leach through from high horizons, AKA Subsoil.
