A field scale survey of soil-crop relationships on a water repellent sandy gravel soil

Water repellent gravelly sands may require different management to water repellent sands to improve grain yield. An increase in gravel content can increase soil organic carbon, decrease the amount (kg/ha) of soil phosphorus and potassium and potentially increase leaching of nitrate. The sandy gravels of the Badgingarra area typically have gravelly soils in the higher parts of the landscape and deep sands in the valleys which may have different soil constraints for crop growth. This transect study was completed to quantify which factors are most important for grain yield in a sandy gravel soil.

Amelioration of water repellent sands – long term impacts

To understand the financial benefit of the many ameliorations options, it is vital to know how long the productivity gains from their implementation are likely to last.  In this trial, large-scale on-farm strip trials with repeated controls using grower seeders and harvesters were applied. This trial deonstrated one-off mouldboard ploughing, rotoary spading and claying.

Clay spreading reduced frost damage and increased crop yield on water repellent deep sand at Moora

In 2016 DAFWA, in collaboration with the WMG, established three claying trials in the region looking at combinations of different clay rates and incorporation methods using a range of tillage equipment. The aim of the trials was to identify the most cost-effective combination/s and produce practical guidelines for farmers seeking long term improvement for enhanced crop productivity on water repellent soils under local growing conditions.

One-off tillage options for water repellent gravel soils

Tillage options for severely repellent sands – which methods work? (2015 Badgingarra)

Strategic deep tillage can be used to ameliorate soil water repellence and subsoil constraints. One-way disc ploughs have a low capital cost and are relatively cheap to modify into a simple but robust tool for partial soil inversion. In this demonstration one-way disc ploughing was compared to rotary spading, a proven amelioration option for repellent sands and a number of deep ripping approaches, including some of the newer very deep rippers.

Herbicide options for annual legume pastures

A growing number of farmers in the West Midlands region use Serradella (and other aerial seeded annual legume pastures) in the pasture phase of their rotation. Controlling weeds in Serradella pastures requires the use of different herbicides and other management strategies (e.g. weed wiping) when compared to traditional subclover based pastures.

Improving timely emergence of crops using seed delivery systems

The aim of this study was to investigate the impact of paired and single seeding configurations on the timely emergence of crops. While the use of paired row seeding configurations has been popular and well adopted among growers in recent years, there is little independent data to quantify the benefit of paired row seeding configurations on the timely emergence of crops over a range of seeding depths and soil types.

Clay spreading on water repellent deep sand (2016)

Clay spreading is a proven method for the amelioration of the water repellence and the improvement of productivity but it requires high initial capital investments and the outcomes can be quite variable.The aim of this trial is to identify the best combination/s of clay application rate and the subsequent method of incorporation in the topsoil (in combination with deep ripping) in order to increase the cost-effectiveness of this soil amelioration option in the northern region.Overall, tillage methods had a significant and negative effect on yield, with only the one-way plough tillage having a positive effect in comparison to the control treatment. Yields increased with increasing incorporation of subsoil clay, although the result was not statistically significant.

Clay spreading is a proven method for the amelioration of the water repellence and the improvement of productivity but it requires high initial capital investments and the outcomes can be quite variable. There is a need for a better understanding on how to best approach clay spreading in soils where the presence of gravel brings new challenges in terms of the application rates and, above all, the following incorporation in the topsoil.The aim of this trial is to evaluate the potential for clay spreading on gravel sands by looking at different application rates of clay and methods of incorporation.

Developing and testing innovative, practical and reliable methods for incorporating lime into acidic sandplain subsoils (2015) (Warradarge site)

Increasing the pH of acidic subsoils in the West Midlands is necessary to increase crop water use and crop yields. A fast way of doing so is to mix lime into the subsoil; spading and mouldboarding are two common methods used in the West Midlands. Both methods are relatively expensive, so this trial aims to assess the effectiveness of a modified one-way plough at achieving subsoil pH change. This trial was located in Warradarge on deep sandy duplex soil.

Diagnostic strips, trials and tribulations (2015)

These projects aimed to address the questions "Is this paddock performing up to potential, and if not, why not?" by persuading interested growers to apply test strips of various management practices (windrows, fertilisers, lime, wetting agents, cultivation) across their paddocks and soil types. The presence or absence of visual responses to these strips should stimulate further plant, tissue and soil sampling for analyses and the total results would be interpreted by experts. Lack of participation in the diagnostic projects, considerable value was gained from opportunistic sampling and diagnostics associated with observed growth variations in paddocks from crops across windrows and from better growth patches.

In season Potassium response in barley (2016)

Potassium deficiency often goes unnoticed until cereals reach late tillering to early stem elongation, by which time it is difficult to predict if an economic response will be achieved if remedied. Granular products such as Muriate of Potash (MoP) require rainfall to become available and crop response is therefore often delayed. Lokomotive (27% K) is a new foliar potassium product from Loveland Industries that has low leaf burn risk and high foliar uptake and has demonstrated potential for correcting potassium deficiency. This trial was designed to evaluate Lokomotive as an in season foliar potassium source for correcting potassium deficiency and compare to muriate of potash.

Long-term assessment of management options for water repellent sandy gravel soils (2015)

Over the past five years considerable research has been undertaken assessing options for water repellent sands but less has been done for the gravel soils.

Variable Rate Irrigation for better potatoes (2016)

Potato growers in the Gingin and Dandaragan areas face significant production challenges due to highly variable soil types under centre pivots. One problem during tuber establishment is where irrigation decisions for lighter soil types result in overwatering on heavier soil types, resulting in rotting of seed pieces on the heavier soils. On the other hand, optimizing irrigation for heavy soil types results in underwatering of seed pieces on lighter soils. The trial is being conducted in Gingin and Dandaragan on sandy and loamy soils respectively. This report covers the pre-trial testing results.

Wheat canopy architecture to enhance resource use efficiency and yield in the high rainfall area (2016)

Anecdotal evidence shows that wheat varieties released in WA are gradually changing from floppy to more erect leaves. This change in canopy architecture (mainly leaf erectness) could have significant impact on yield across the rainfall zones of WA. In other crops like rice and corn, an erect leaf canopy has significantly increased yield by 20% or more. We believe this change in canopy architecture might have implications for improving wheat yield and that leaf erectness may be a useful trait for future breeding.Conducted on yellow sand in Moora, this experiment was designed to test the effect of wheat canopy architecture on wheat yield.
