Shift in grazing management boosts capacity
Case study: Andrew and Scott Colvin
Location: Blackwood Creek, Tasmania
Property size: Nosswick — 950ha, Maitland — 160ha
Average annual rainfall: 750mm plus irrigation (nine pivot irrigators and 19 pivot circles)
Soils: Light duplex soils — poorly draining soils prone to waterlogging during winter
Enterprises: Mixed farming system — sheep (4000 Coopworth breeding ewes), irrigated and dryland pastures (white clover, annual ryegrass), cropping (annual ryegrass seed, poppies, beetroot, carrots, broccoli and processing peas)
- A shift from set stocking to intensive rotational grazing has boosted weaner growth rates and pasture productivity.
- Allowing pasture a recovery phase following intensive grazing is encouraging grass tiller production and increasing groundcover.
- A “measure-to-manage” approach allows for more timely decisions around matching feed availability and livestock demand.
