6.2 Purpose of in-depth soil loosening
• In-depth soil loosening is a soil-improving intervention that mechanically scarifies compacted layer of
soil. Depth looseners can also be used in soil-protection cultivating systems where the soil is in-depth
loosened with a minimum surface failure. This can be effectively used with deep soils in more arid areas
where there is a danger of wind erosion.
In-depth loosening can also be used for other purposes such as:
• increasing water-accumulation capacity of soil and/or
• draining surface water into deeper parts of the soil profile
Loosening the compacted layers under topsoil enables crop roots to penetrate deeper, which results in
higher crop yield.
CONDITIONS FOR EFFECTIVE IN-DEPTH SOIL LOOSENING
• The basic condition for effective in-depth loosening (around 0,6 m) is the appropriate soil moisture in
the depth of loosening. The soil should be crumbly and always under the limit of plasticity and it must not
show plastic deformations when being loosened. Loosening soil with excessive moisture can be
counterproductive. If the soil to be loosened is extremely dry, the working resistance acting on the loosener
is enormous. To decide on the soil conditions it is advisable to use a probing rod. When applying pressure
on a soil sample, the soil should fall to smaller lumps.
