Maximising the response to applied nitrogen will be on the agenda at the free Nitrogen Efficiency Field Day hosted by Riverine Plains next week.
Held at Henty on Tuesday, June 6, the field day will focus on improving nitrogen fertiliser uptake in broadacre crops and ensuring spreading equipment is working as designed.
‘‘Many fertiliser spreaders distribute fertiliser unevenly, which can then lead to unevenness in crop growth, development and maturity,’’ Riverine Plains extension officer Cassandra Schefe said.
‘‘Calibrating equipment helps achieve a more even fertiliser throw, which can then improve yield potential.’’
Fertcare registered calibration specialist Russell Nichol will demonstrate calibration techniques on a number of machines and discuss his process with farmers so they can use the techniques on their own equipment.
Foundation for Arable Research Australia senior field research officer Michael Straight said a portion of applied nitrogen fertiliser could be lost to the atmosphere as nitrous oxide gas, particularly when conditions were extremely wet.
‘‘These losses reduce the efficiency with which applied nitrogen can be used by the plant,’’ Mr Straight said.
‘‘We have just finished a project looking at nitrous oxide emissions in cereal crops and now have a better understanding of how nitrogen applications can be timed to improve plant nitrogen uptake efficiency, and will be presenting these findings on the day.’’
The field day will start at 9.30am at 452 Henty-Pleasant Hills Rd, Henty. Morning tea and lunch will be provided.
