Response of Italian ryegrass to different fertilisers on a nutrient deficient soil locations
Aims

To show the importance of soil testing, and linking this with applying the right nutrients.

Key messages
  • The Italian ryegrass responded well to phosphorus additions in the range of 15-60 kg P/ha and required the higher rates to be applied unless nitrogen, potassium and sulphur were also included.
  • In regard to the addition of potassium, the relatively wet year meant there was unexpectedly no negative affect on plant establishment by banding potassium fertiliser in the soil at sowing which is generally not recommended.
