High Rainfall Zone Canola Variable Rate Nitrogen (VRN) Project (ELD118)
Investigating the accuracy of NDVI and NDRE in detecting canola response to nitrogen to create a variable rate map.
New field-based tools to rapidly assess crop nitrogen and stress status (UA316)
Improving the ease of measurement of plant trait components, water soluble carbohydrates and nitrogen content through use of non-destructive, real-time measurements carried out by a handheld device.
Efficiency of various fertiliser N products on sandy soil types (AS116)
Glasshouse trials using two sandy and one calcareous soil from three South Australian locations tested nitrogen product efficiency at two different soil moisture levels for wheat biomass production.
Potential N supply and mineralisation as predicted by DGT (UA314)
DGT is a new measurement technique that could potentially provide a more accurate alternative to current N measurement methods. Results were compared with current N methods.
Field evaluation and development of advanced strand medic lines (S131OR)
SARDI conducted trials in the Murray Mallee, upper Eyre Peninsula and upper Yorke Peninsula evaluating traits of new medic lines to assess their suitability for less intensive cropping operations.
