Soils. Profiles and processes
Description
This program looks at the way soils can vary even within a small area of a forest. A well-developed podzol is examined in detail, with samples taken from the center of each horizon and then analyzed for organic content, soil acidity, mineral content, and particle size distribution. The measurements and analyses demonstrate why three soil profiles can be so very different in closely contiguous areas, with the same underlying sand, the same climate, and similar if not identical vegetation. The differences are due not to soil types, but to different processes at work.
