Imagine a root of a cotton plant growing in the upper horizon of an irrigated soil in California’s Imperial Valley. As the root attempts to draw water molecules from this soil, what forces (potentials) must it overcome? If this soil were compacted by a heavy vehicle, which of these forces would be most affected? Explain.
