Subsoiler

As deep loosening is called in agriculture and horticulture mechanical breaking compacted, root growth and hindering if necessary. also to standing water layers in the subsoil from about 40cm depth. Cause of sub- soil compaction can be, for example, plow pans, hardpan or history of construction using heavy machinery. For deep relaxation and a special grubberähnliche mehrzinkige devices with rigid or by tractor PTO driven mobile loosening shares are used; at Slade condensations sometimes sufficient but also the use of a particularly stable built Schwergrubbers. The current work depths of 60 to 90 cm require the application of a major tensile force by the tractor. Order to produce a cross- breaking ( loosen ) to reach the sub-floor, the floor should be as dry as possible and thus only slightly plastically deformable. To stabilize the loosened soil, the deep loosening is often associated with a Meliorationskalkung.
