To do so the project will measure the grain yield and gross margin outcome of each soil ameliorant treatment at each site.

To determine whether the seed inoculant, Pr-70, is economical on acid sands at Jibberding. The inoculant will be used in conjunction with increasing rates of phosphorus to determine the most profitable return for farmers in the region.

To compare four different GM canola varieties in a farmer sized trial and monitor these plots throughout the growing season with the potential to compare yield at harvest.

To evaluate the grain yield and economic benefit of soil amelioration and controlled traffic practices on a broader range of soil types across the grain growing region of WA.

This trial aims to increase the knowldege and adpotion of deep ripping techniques and controlled traffic to allieviate non-wetting soils, compaction and waterlogging. 

The trial aimed to look at the long term effects of ripping on crop yields by monitoring crop performance of the treated plots for three seasons post-ripping. 

The trial aims to raise awareness amoung growers around the decline in the effectivness of ripping over time, and the risk of re-compaction if controlled traffic is not properly implmented. 

To demonstrate establishment, management and viability of legume phase options in cropping rotations with appropriate agronomic management packages.

To demonstrate that, in the right season, ripping affects nitrogen uptake efficiency and availability to crops.

To assess the impact of full inversion mouldboard ploughing and partial inversion rotary spading on soil repellance, crop growth and grain yield using large scale on-farm trials.

To assess the new herbicide Sakura on Annual Ryegrass control/suppression in wheat

To investigate the effects of rates of initial and subsequent applications of manganese on lupin yields grown on Mn deficient soil

To determine the residual value of nitrogen (N) and phosphorus (P) applied in 2011.

This trial was designed to test whether wheat growing on soil with low K levels will benefit from K application enabling it to make full use of applied N during the crop growth cycle. High yield potential crops in the area have shown decreased rigidity in foliage and tillers, with low Cu status suspected. Uptake of Cu can be influenced by rapid growth and N uptake. Application of Cu before rapid plant expansion was also to be tested.

This demonstrations was conducted for three significant reasons.

• 1. Assess the potential yield losses when increasing the seed row width for the benefits of subsequent inter-row (no-till) cropping;
• 2. Determine if nitrogen application efficiency can be increased in wider row spacing scenarios by applying product either up front or in crop;
• 3. Assess the varietal response to row spacing width to determine yield in response to nitrogen timing and row widths.
