Management considerations
Mottles in the subsoil indicate reduced permeability and periods of waterlogging. The massive topsoil also may create a barrier to soil penetration. The application of gypsum and introduction of organic matter may assist the development of topsoil structure while better site drainage will reduce periods of waterlogging.
