Improving fertiliser utilisation in no-till systems locations
Aims

To use the increased concentration of fertiliser granules in low SBU systems to measure any advantage of fertiliser uptake

Key messages
  • No measured improvement in phosphorus uptake through low seed bed utilisation systems.

Acknowledgments
  • Thanks to Nathan Little for the use of his land. Thanks to Brenton Spriggs for his untiring help, especially at seeding time (3 days in one paddock is a little much)!
  • Thanks to SANTFA sponsors CASE IH, Yetter, K-Hart, Flexi Coil and Agmaster for supplying equipment for the trial.
  • Thanks to Jack Desbiolles from AMRDC, Uni SA for his input in to the trial.

Port Kenny 2009

Sow rate or Target density Wyalkatchem wheat was sown at 50 kg/ha for a target population of 150 plants/m2.
Sowing machinery

The SBU combinations were accomplished by using three planting options with differing levels of seed spread. Seed spread of 40 mm and 65 mm was achieved using knife points and Agmaster boots. 5 mm seed spread was achieved using Yetter wavy coulters and K-Hart v-paired discs. The three sowing systems were each set on 203 mm, 254 mm and 304 mm row spacing to provide a range of SBU ratings from 3 % to 32 %.

Fertiliser

Triple super (0:20:0) was used to deliver 5 and 10 kg/ha of phosphorus. Triple super was chosen as the product for the trial to avoid confounding the results with nitrogen rates when fertiliser rates were increased to the 10 kg/ha P level.
