Contributor Fitzgerald Biosphere Group Inc.
Trial location(s) Jerramungup, WA
Sources of potassium fertiliser (Camm wheat) locations
Aims

To compare the effectiveness of potassium banded in K Till and Flexi NK at seeding to potassium top dressed as Muriate of Potash before seeding.

Key messages

K Till has proven to be more effective than other sources of potassium in past trials. Flexi-NK (18%N and 10%K w/v) is a new CSBP liquid fertiliser offering similar potential.
