The project will establish four paddock scale barley demonstration sites (Frankland River, Mount Barker, Woogenellup North and Green Range) with a nil control and four in season N strategies reflecting likely grower supply scenarios. SCF will run a fortnightly plant tissue testing program from early tillering to late stem elongation, supported by baseline and follow up soil N testing, two NDVI timings and harvest yield mapping, and will extend results to growers through a simple traffic light alert system via monthly e news updates, interim short videos and at least one field walk. The intended outcome is improved confidence and timeliness of in season N decisions—matched to crop stage, rainfall received and fertiliser already applied—so growers can better protect yield and nitrogen use efficiency under constrained inputs.
