Break crop selection for Eyre Peninsula low rainfall farming systems Farming systems in the low rainfall zone of southern Australia are dominated by cereal production. There is increasing concern about grass weed and soil-borne disease pressure, diminishing soil fertility (particularly nitrogen), and water use efficiency, as a result of continuously cropping cereals. Break crops have a key role to play in addressing these issues, as well as diversifying crop production and economic risk, and maintaining long-term sustainability of the system. However, there remains a lack of information available to growers about choosing the break crop best suited to their situation, as break crop development to date has largely occurred in medium and high rainfall zones. The aim of this research is to identify the best break crop options for different climate, soil type and biotic stress situations within major cropping regions of the southern low rainfall zone.

Dryland Legume Pasture Systems: pasture demonstration sites 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 in low to medium rainfall areas. 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, biserrula and bladder clover can improve livestock production while reducing nitrogen requirements, weeds and diseases for following crops. The extent to which these new legumes establish, grow and persist on South Australia's alkaline sandy soils requires clarification. The demonstration sites are primarily an extension tool, unlike research trials requiring detailed data collection. The purpose of these sites is to gather information on regional legume performance, including benefits to the crops that follow.

Dryland Legume Pasture Systems: pasture demonstrations on lower Eyre Peninsula This article will report on findings from two pasture trials conducted on the lower Eyre Peninsula in the 2019-2021 growing seasons. The trials are part of the demonstration component of the Dryland Pasture Legume Systems (DLPS) project developed with the former LEADA committee/AIR EP Medium Rainfall RD&E committee to answer several questions about how pasture performance could be improved in the region. Demonstration 1: What is the best pasture species/ mix of species to plant in paddocks with differing soil types? Background Paddocks across the region often have soil types that vary, ie. changing from heavier flats to sandier rises, with pH varying from below 6 to above 8. Getting pasture species established and maintaining good production levels across this landscape is often challenging.	Agricultural Innovation & Research Eyre Peninsula GRDC	2019	Ungarra SA
