Top tips for growers around potassium- podcast

In this episode of our GRDC Communities Podcast, Tony Cox interviews James Easton, senior agronomist from CSBP, about how producers should address the depleted state of Western Australian subsoils. He emphasises the need to conduct deep soil testing to determine the extent of potassium deficiencies and also discusses the effect of fertiliser forms and deep tillage on the availability of potassium to crops.

In this episode, we discuss:

  • how producers should assess what their potassium requirements are
  • suggestions for growers to ensure they’ve got sufficient potassium in their soils
  • trials currently underway with compound fertilisers
  • the effects of spading and mouldboard ploughing on potassium availability.
