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.
This trial aimed to evaluate early foliar disease suppression of soil applied fungicides, compare early soil disease control to a foliar only strategy, compare efficacy of different foliar fungicides on yield at a ~Z31 and Z39 applications as well as comparative of seed treatments.
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.
