The authors of this paper note in the conclusion: “Be adaptive in your fertilizer management program. Respond to the opportunities that are offered to put the right nutrient in the right place at the right time, and chose the right combination of products to match the soil nutrient status. This will involve a good understanding of the variation in profile nutrient status from field to field, and also understanding how seasonal conditions may impact on those application decisions”.   Please access the full paper via the link below if this research interests you.

The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.

Take home messages from the paper include:

  • A critical success factor for cropping systems that rely heavily on stored soil water is co-location of plant nutrients with moist soil and active roots
  • Our current fertilizer management practices need refinement, with low efficiency of fertilizer recovery often associated with nutrients and water being in different parts of the soil profile
  • There needs to be greater consideration of placement and timing of fertilizer applications to improve fertilizer nutrient recovery
  • Declining native fertility reserves means more complex fertilizer combinations will be needed to meet crop demands.
