The "loss of humus and the consequent collapse of topsoil is referred to as the mineralization of the soil, because what is left is just the gritty mineral content—sand, silt, and clay—devoid of humus." The loss of topsoil would mean "the mutually supportive relationship between plants and soil" is broken. When mineralization occurs, the soil is no longer able to support plants.
