Southern Farming Systems chief executive officer Jon Midwood says there is scope for late-season nitrogen application to become more popular, given a soft finish to the season... "Some of the sites we trialled already had adequate nitrogen because of high residual levels, or the grower had applied more nitrogen prior to GS32," Mr Midwood says... "Also spreading widths are getting wider and there may be a case for considering liquid fertilisers because they can be applied through a boom-spray at the correct width, compared to a spinning disc spreader which can be limited by wind conditions and machine set-up," Mr Midwood says...

Urease inhibitors act by slowing the rate of urea hydrolysis (the process by which N is released from a granule), by inhibiting the action of the enzyme urease, and by doing this the elevated pH hotspot that occurs around the granule is lessened and this reduces the risk of NH 3 loss... The paper presents laboratory and field experiment data that investigated the impact of the urease inhibitor NBPT (Green Urea TM 7 or 14 in Australia), on rates of urea and NH 3 loss... The experiment showed that NH 3 loss in autumn was greater than in spring (Table 1) and that whilst the inhibitor was effective at both times, the real benefit in terms of N saved was only seen in autumn...
