ADLib Glossary (S)

More Information:


On heavy or poorly structured soils it is occasionally necessary to loosen the soil to a greater depth than that reached by normal cultivations, in order to improve drainage and root penetration. Subsoiling machines (subsoilers) for this purpose can operate at depths from 300-600 mm and at spacing as close as 1 metre. Subsoiling may be used to counteract effects of soil smearing and compaction resulting from handling of soils in wet conditions.
