Katherine Rural Review P a g e | Action on the Ground update Teagan Alexander, Technical Officer, Katherine Research Station The Australian Government funded Action on the Ground project Reducing greenhouse gas emissions through improved nitrogen management on Northern Territory farms is full steam ahead for 2015, its third and final Wet season trial. This year the trial is taking place in a paddock of Jarra grass at Maneroo Station in the Douglas Daly with thanks to the Howie family. Four different fertiliser rates have been applied (60kg/ha Entec urea, 80kg/ha Entec urea, 80kg/ha Urea and zero fertiliser) and replicated three times. The Entec urea contains DMPP, a nitrification inhibitor that cuts down on emissions of the greenhouse gas nitrous oxide. The wet season was not without a rocky start. We had some technical difficulties with the Automated Manual Sampling System (AMSS) equipment as well as some kind of critter chewing on the seals while the AMSS chambers were out in the paddock! As much as we were excited at the prospect of using the AMSS the wet season was getting away from us which resulted in us using our trusty, old manual chambers instead. After applying the fertiliser we got enough rain for it to wash in and after two weeks the colour difference between the different fertiliser rates was noticeable. With the trial nearing the end we look forward to the results of which fertiliser type and rate are the most cost effective with the least emissions for hay crop production in Jarra grass.
