| Abstract: | Key findings • The dry spring in 2012 restricted N uptake from post sowing N, but this was not lost. • Topdressed nitrogen at rates greater than 50 kg N/ha (applied mid-August 2012) significantly increased soil nitrogen levels in 2013. • Residual soil nitrogen was retained within the top 30 cm of the soil profile. • Nitrogen applied at sowing in 2012 had no significant residual benefit in 2013, presumably due to denitrification caused by waterlogging. • Take a deep N test to assess nitrogen requirement. |
