Barley grass continues to be a major grass weed in cereal cropping regions on the upper Eyre Peninsula (EP). Swathing a cereal crop involves cutting and collecting the cereal crop and weeds into windrows at 20 to 40% grain moisture and allowing it to dry. Having the weed seeds cut and in the windrow before the seed heads shatter and before tillers fall over (lodging), may allow greater weed seed collection when using a chaff cart or windrows. Swathing early then harvesting for weed seed collection needs further evaluation as it may provide farmers with another tool for integrated weed management, especially for barley grass that matures and sheds seed before crops ripen.

This project aimed to explore different management strategies to overcome copper deficiency in cereals. The project compared the effectiveness of copper sulfate and copper chelate applied either as liquids banded at seeding or as a foliar spray. The project also evaluated the effect of different timings of application of the foliar sprays and their efficiency.
This project aimed to benefit local and South Australian farmers by establishing an independent best practice management guide for copper applications for the future.

Barley grass continues to be a major grass weed in cereal cropping regions on upper Eyre Peninsula (EP). The use of unmanned aerial vehicle (UAV) technology to identify and assess barley grass populations in paddocks and monitor potential resistant populations may be a useful tool for farmers. This approach was tested in three paddocks on upper EP Minnipa Agricultural Centre (MAC), Minnipa Hill and Yaninee using a UAV during the 2017, 2018 and 2019 growing seasons at three different timings, with paddock transects conducted to verify grass weed density in paddocks. In 2019 grass weed escape paddocks were targeted at MAC and Condada in the final flights.

The aim of the research was to determine if the UAV imagery could monitor the grass weed populations across seasons in crops and pastures, if resistant weed patches were continually in the same area of the paddock and if the information could be useful for farmers to adopt this method to better target grass weed control.

This was the second year of a three-year trial, funded by the South Australian Grains Industry Trust (SAGIT), to evaluate the nitrogen fixation capabilities of various legume species commonly grown on Kangaroo Island.

In this second year, the trial was set up to answer the following questions:

• Which of the four legume species had fixed the most nitrogen (N) in the 2016 season?
• How much N did these legume crops fix?
• How much of the N fixed by the legume was utilised by the following crop? Concurrently, how much N was lost through leaching or denitrification?

• Trials were implemented to compare break crop productivity and profitability on major soil types in the northern South Australian Mallee. This information will help farmers in the region to select the most appropriate break crop for their farming system.

To inform members about airborne imagery: the taking of photographs of the ground and crops from a direct-down position. Platforms for airborne imagery for agriculture include satellites, fixed-wing aircraft, unmanned aerial vehicles (UAVs or “drones”).
