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?

The aim of the ‘Yardstick’ project is conduct agronomy demonstrations that will enable growers to reduce crop selection risk through better understanding of crop performance with different crop types/varieties, timings of sowing and nutrition.

Regional specific agronomy has been identified as a need by growers in RCSN Open Local Forums, in particular in using regional specific agronomy demonstrations to assist decision making of growers.

The aim of this project was to use best district practice to examine if newer varieties respond differently to increasing nutritional inputs and whether this can be exploited by growers.

This was done by measuring crop performance with different sowings times and nutrition regimes, representing different decision-making scenario's depending on budget and seasonal rainfall.

This information should then assist grower’s decisions with variety specific agronomic management.

Multiple trials around the theme of improving and quantifying the benefit of pulses to subsequent crops. This will include comparisons of crop types in 2022, followed by cereal crops in 2023, and techniques to increase biomass (early sowing) and increase N fixation (rhizobia studies) 

The primary purpose of this project was to provide additional data from a range of different agricultural scenarios (climate, soil type, management practices) in the Western Region to validate and enhance the ability of the BlacklegCM app to more accurately determine the return on investment various management decisions may provide to a grower in any given year. The secondary purpose of this investment is to increase the grower and advisor confidence in the use of decision-making tools to manage disease in canola in the Western Region, in particular increase the awareness and use of the BlacklegCM app.

The aim of this work was to use a range of tools to determine if we can be confident that the SclerotiniaCM app is producing reliable outputs that will help canola growers make informed management decisions in a given season

To investigating if applying fertiliser according to productivity zones is more profitable than blanket applications of fertiliser across the whole paddock. We aimed to design trials to demonstrate to growers that matching fertiliser inputs to productivity zones will increase whole paddock profitability compared to blanket applications of fertiliser. We also aimed to use off the shelf tools (Silverfox/Sky Plan, Nulogic etc) that growers could access to enable them to follow our procedures to adopt VRT across the whole farm.

This trial aims to assist growers in making informed decisions around the construction of sub-surface drainage to reduce the impacts of waterlogging on crop production and farm profitability. By 2024, 45% of growers whose properties are affected by waterlogging will have a good understanding of the yield benefits and time to return on investment of installation of on-farm sub-surface drainage and ability to implement on-farm.

Understanding return on investment of sub-surface water management options for waterlogged areas in the Western Region.

This investment aims to assist growers in making informed decisions around construction of drainage to reduce the impacts of waterlogging on crop production and farm profitability. This will be achieved through grower participation in the planning, development, monitoring and maintenance of the drainage installation trial sites. Data (cost of implementation/ maintenance, water movement, establishment, biomass, yield etc.) from within the zone of influence of the drainage and outside this zone at each site will be collected 
over time to give growers a better understanding of the improvements in yield and time to return on investment at each site.
