- •
Fe-cemented layers are found in the soils of golf putting greens across the USA.
- •
The layers occur at the boundary of the A and C horizon or the C horizon and gravel layer.
- •
Irrigation, Fe fertilization, and a textural discontinuity are key factors in the formation of these layers.
- •
Layers may form at rates of 1.5 mm per year and may become cemented in 10 years.
