Why use the SUM or SUH to cultivate below the seedbed?
Subsoiling is carried out on some land to help overcome poor localised drainage, reducing crop yields, declining drought tolerance,
slow germination and a host of other problems. With SUM and SUH subsoilers, the aim is to encourage the use of these tools as an
integral part of planned soil improvement. By working down to depths of up to 550mm, New Holland subsoilers do more than just
repair existing damage in the soils rootzone. They enhance the soil and improve its structure with regular use each season.
Key to this is the action of the subsoiler legs to loosen the rootzone without mixing soil within the soil profile. This action helps to
improve air and nutrient flow down through the soil layers, encouraging root formation deep into the soil.
With repeated use over the seasons, combining the action of SUM and SUH subsoilers with minimal cultivation tools such as the
New Holland SDM and SDH cultivators will help develop the soils structure and repair damage, alleviate traffic pans and erase yield
supressing compaction. Natural soil health is encouraged by improving the flow of air and moisture in the deep rootzone.
Minimal tillage cultivators worked in tandem with SUM and SUH cultivators can eliminate compaction at all levels in the soil profile, as well as
ensure air, moisture and nutrients penetrate deeper into the soil for enhanced root growth, deeper into the soils. This will improve draught tolerance
and enhance crop vigour for improved plant health and yields.
