Precision Agriculture-making it work on KI

Year 2 - Improving nitrogen use efficiency via legumes in high rainfall cropping

This was the second year of a three-year trial, funded by the South Australian Grains Industry Trust (SAGIT), to evaluate the nitrogen fixation capabilities of various legume species commonly grown on Kangaroo Island.

In this second year, the trial was set up to answer the following questions:

  • Which of the four legume species had fixed the most nitrogen (N) in the 2016 season?
  • How much N did these legume crops fix?
  • How much of the N fixed by the legume was utilised by the following crop? Concurrently, how much N was lost through leaching or denitrification?
