What characteristic does 'platt' refer to when describing soil structure?

The term 'platt' when describing soil structure refers specifically to flattened layers. This characteristic can significantly influence various soil properties such as drainage, aeration, and root penetration. In soils with a platy structure, the flattened particles tend to stack vertically, which can restrict the movement of water and roots, leading to various agricultural issues. Correctly identifying this structure helps horticulturists and agronomists to understand the limitations and potential management practices needed for optimal plant growth in such soils.
