• Increase farmer knowledge about the N2O emissions made from fertiliser and legumes;  
• Reveal options available to reduce N20 emissions; and
• Provide information about nutrient use efficiency to maximise productivity.

• To investigate the potential to incorporate a mixture of perennial species into farming systems in low-rainfall areas across southern Australia.

To assess dual purpose wheat, triticale and oat varieties for dry matter production, recovery from grazing and grain yield.

• Which dual purpose varieties respond to Gippsland’s climatic conditions?
• Which new varieties may have commercialization potential?
• Which varieties are best suited to forage and feed grain production?

The Grain and Graze program was keen to test the findings from extensive trial work with a group of farmers to see if the theories of grazing cereals provided the desired response under a range of conditions and farming situations. The financial gain from the exercise was also calculated.

To compare the yields of crops grown under four different farming systems common to the southern Mallee region.

To assess the Farming Systems trial for changes in the soil properties/health that may have occurred between each of the four systems since 2000.

To measure effect of gibberellic acid application and grazing timings on the biomass production and feed quality of oats.

To assess the impact of (and interaction between) grazing and frost damage on the grain yield and quality of a range of winter and spring cereal varieties sown at two times of sowing.

A long-term study was established at the Minnipa Agricultural Centre from 2008 to 2014 (EPFS Summaries 2008 to 2013) to assess the impact of grazing on crop and pasture production and soil health and also to evaluate this from a systems perspective.

The seven year demonstration with a wheat, wheat, pasture (volunteer and sown annual medic), wheat, pasture (self-regenerating annual medic), wheat and wheat rotation was also established to determine whether productivity could be improved under a higher input system compared to a lower input and more traditional system and what affect this had on soil fertility.

To test whether soil fertility and health could be improved under a higher input system (e.g. higher fertiliser and seeding rates, establishment of improved pasture) compared to a lower input and more traditional system (district practice seed and fertiliser inputs, volunteer pasture).

The six year (2008-2013) rotation of: wheat, wheat, pasture (volunteer and sown annual medic), wheat, pasture (annual medic – self regenerating) and wheat, was also split into grazed and un-grazed treatments in both the high and low input systems to establish the relative impact of grazing.

A long-term study was established at the Minnipa Agricultural Centre from 2008 to 2015 (EPFS Summaries 2008 to 2014) to assess the impact of grazing on crop and pasture production and soil health and also to evaluate this from a systems perspective.

The eight year demonstration with a wheat, wheat, pasture (volunteer and sown annual medic), wheat, pasture (self-regenerating annual medic), wheat and wheat rotation was also established to determine whether productivity could be improved under a higher input system compared to a lower input and more traditional system and what affect this had on soil fertility.

The GRDC project ‘Maintaining profitable farming systems with retained stubble - upper Eyre Peninsula’ aims to produce sustainable management guidelines to control pests, weeds and diseases while retaining stubble to maintain or improve soil health, and reduce exposure to wind erosion. The major outcome to be achieved is increased knowledge and skills allowing farmers and advisers to improve farm profitability while retaining stubble in farming systems on upper Eyre Peninsula (EP).

The Minnipa Agricultural Centre S3S pasture trial was established in 2013 to assess barley grass weed management with a two year medic pasture break. The trial had different grass weed management and tillage treatments imposed in 2013 and in 2014. The trial was then sown with wheat in 2015.
