All clay delving treatments significantly improved crop yield up to 770kg/ha in the first year of the trial. Though delving treatments did not significantly improve crop emergence, soil strength was reduced and root abundance was increased at depth in the clay-rich B horizon. Evaluating the physical changes of the soil through delving is important ...

Residual nutrients are difficult to ascertain at modern crop input rates on many soils and make relatively low contributions to yield in comparison to new season applications. Soil testing and analysis is important to identify responsiveness but benchmark values are not “critical” as their name suggests and require careful consideration....

Short-term soil water repellence mitigation options, such as improved furrow sowing and use of banded soil wetting agents, offer a relatively low cost way of improving crop establishment and performance across all the water repellent soils in a seeding program. Long-term soil water repellence amelioration options, such as clay spreading or delving,...

A new decision tool called ROSA (Ranking Options for Soil Amelioration) can be used by agronomists / consultants / growers to help understand the most cost-effective way to spend a limited budget on soil amelioration. Using ROSA, we estimate that the indicative value of lost grain production due to soil constraints is, on average, $330/ha costing t...

In this paper, we compare the emergence, growth, seed production and shedding time of annual ryegrass, great brome grass, barley grass, doublegee, sowthistle and wireweed, growing in a wheat crop....

Misuse of fungicides and poor disease management practices have an impact on everybody. Overuse of fungicides with the same mode of action will speed up fungicide resistance. We can limit the development of fungicide resistance by using the lowest doses that give good control, appropriate MOA rotations and employing IDM practices including crop rot...
