Sumo GLS wrestles compaction
A recent demonstration of a grassland subsoiler in the heavily compacted car park at Mystery Creek impressed visiting dairy farmers.
Designed for deep vertical tillage, the Great Plains inline subsoiler shatters yield-robbing compaction layers.
These layers are a known effect of horizontal tillage tools such as ploughs and discs, and of tractors or continuous repeated traffic.
The subsoilers have a working depth of 30-40cm with easily adjusted depth wheels. They are designed for use in autumn to help loosen the soil profile and restore uniform density but with minimal topsoil disturbance.
The subsoiler’s frame is made of high tensile, 9.5mm walled tubing for strength and durability. They come with 70cm (6 shank) or 75cm (5 shank) spacings.
A no-till, 25cm wide, winged point is used with the 19mm no-till leg to minimise surface disturbance yet maximise the soil shattering effect below the surface.
At the rear of the machine, individual 41cm diameter roller assemblies, made from 2.5cm solid bars, level the treated surface, enabling single pass seedbed preparation.
The shanks are protected against stones, rocks or timber by a horizontally mounted coil spring protection system with a trip force of 1360kg.
Academic Dr Mike Joy and his employer, Victoria University of Wellington have apologised for his comments suggesting that dairy industry CEOs should be hanged for contributing towards nitrate poisoning of waterways.
Environment Southland's catchment improvement funding is once again available for innovative landowners in need of a boost to get their project going.
The team meeting at the Culverden Hotel was relaxed and open, despite being in the middle of calving when stress levels are at peak levels, especially in bitterly cold and wet conditions like today.
A comment by outspoken academic Dr Mike Joy suggesting that dairy industry leaders should be hanged for nitrate contamination of drinking/groundwater has enraged farmers.
