Responsive farming for soil type at Mudamuckla locations

To manage risk through tailoring inputs to the different production zones potential by using variable rate technology.

Key messages
  • 4 kg/ha of P as a blanket application increased grain yields and gross margins over nil P in all 3 soil zones, however applying a variable rate to the medium soil zone of 8 kg P/ha improved gross margins over the 4 kg/ha rate.
