Dryland Legume Pasture Systems – Boosting profit and reducing risk in medium and low rainfall areas
Summary
Over the past three decades there has been a shift from integrated crop-livestock production to intensive cropping in dry areas which has significantly reduced the resilience of farms. Intensive cropping is prone to herbicide resistant weeds, large nitrogen fertiliser requirements, and major financial shocks due to frost, drought or low grain prices. A pilot project with MLA and AWI in WA and southern NSW has demonstrated how novel pasture legumes such as serradella, biserulla and bladder clover can improve livestock production while reducing nitrogen requirements, weeds and diseases for following crops.
This new project will develop recently discovered pasture legumes together with innovative management techniques that benefit animal and crop production and farm logistics, and promote their adoption on mixed farms over one million hectares in the low and medium rainfall areas of WA, SA, Victoria and southern NSW. The project is also aiming to halve financial risk.
There are five integrated programs of work:
- Well adapted to major soils in dry regions; fix abundant nitrogen; produce quality stockfeed to fill gaps.
- Harvestable with conventional machinery to minimise seed costs.
- Of suitable seed dormancy to enable summer sowing or natural regeneration after crops.
- Tolerate cropping herbicides, legume diseases and pests.
