Understanding soil N levels coming into the 2023 cropping season will allow growers and advisors to make targeted decisions on N application rates, N application timings and crop rotations.
Research from a five-year experiment in Curyo found that N bank strategies of 125kg N/ha or Yield Prophet® 50% are the most profitable over time (Hunt et al. 2022). This work was supported by the Mallee Catchment Management Authority through funding from the Australian Government’s National Landcare Program.
Coming into the 2023 season, knowing the starting soil N allows growers to make targeted decisions that lead to better returns, such as deciding to grow a pulse in low N paddocks rather than applying large amounts of urea, even though urea prices are coming down) to meet yield potential.
