Aims:

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.

Aims:

Agricultural soils are the main source of emission of the greenhouse gas (GHG) nitrous oxide (N2O) to the atmosphere. N2O is a potent GHG which lasts in the atmosphere for 114 years and has a global warming potential of approximately 300 times greater than that of carbon dioxide over a 100 year timescale. Agriculture accounts for 16% of Australi… read more

Crop type: Wheat 1 trial Crop Type Fertiliser Rate
Wanilla, SA Duplex sand over loam
Research organisatons
Funding source

Aims:

To measure and quantify N2O emissions from wheat grown in rotation with canola, pulses and legume pastures at two sites in low and medium/high rainfall farming systems of the Eyre Peninsula, while assessing best management practices that local farmers can adopt to reduce the risk of N2O losses and ultimately improve the paddock’s crop producti… read more

Minnipa Agricultural Centre, SA Wanilla, SA Calcareous red sandy loam
Research organisatons
Funding source

Aims:

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).
