Principles of managing man-made soils
1989
Stewart, V.I. | Scullion, J.
Assuming that there is no major chemical toxicity or deficiency, the major limitation in man-made soil is the loss of its natural structure, which, in turn, controls the air-water balance. Where such a soil has < 70% sand content this loss may adversely affect potential for use. Examples of man-made soils--sports turf and replaced opencast coal mining land--are used to illustrate principles of management. Two strategies exist: to encourage earthworms, thereby promoting effective site drainage by infiltration or, to limit their activity and rely mainly on surface shed. The implications of each of these soil options for wider management and use are discussed.
