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.

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

Trial 1: Lime comparison trial 
The use of new pH mapping technologies has increased the awareness and identification of soil acidity in many districts. However, there are several aspects of soil acidity management which remain a problem for growers. This trial aimed to investigate a range of lime and acidity management factors outlined in the three key areas below. 

• Lime source 
• Lime rate and particle size 
• Decline of soil pH from sulphur applications 

Trial 2: Comparison of lime incorporation techniques 

Acidic layers of soil are increasingly being identified in the topsoil (0-10 cm) and subsurface soil (10-30 cm) of no-till farming systems. Stratified low pH soil layers need appropriate lime treatment to maintain and prevent the decline of soil pH further. Surface application of lime alone is unlikely to raise the pH in subsurface layers quickly. Recent work has reported lime movement as little as 1 cm – 2.5 cm per year (Fleming et al. 2020, Burns et al 2017). Given the slow movement of lime, incorporation and mixing of surface applied lime to depth is expected to accelerate the movement of lime.

There are a range of machinery options that can provide different levels of lime incorporation and to different depths, such as cultivation, deep ripping with or without inclusion plates, spading and combinations of these. This trial was designed to investigate which of these are most effective on a sandy soil with stratified soil acidity at Bute.

The aim of this trial is to evaluate and analyse the effect of deep ripping with inclusion plates on moving surface-applied lime into acidic sub-soil of deep sandy duplex. Additionally, this trial tested farm-sourced lime against commercial grade lime. 

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 assess the potential yield losses when increasing the seed row width for the benefits of subsequent inter-row (no-till) cropping;
• To determine if nitrogen application efficiency can be increased in wider row spacing by applying product in a linear manner.

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.

The aim of the competition is to see which team produces the highest gross margin crop (not necessarily the highest yielding crop) against a background of uncertain input and grain prices and unknown growing season rainfall.
