In low rainfall areas or in drier seasons rainfall may be too low or variable to get consistent results from delayed N. Figure 3b shows that the risk associated with a delayed N strategy increases at sites were yields were less than about 2,500 kg/ha: the variation in the response to N applied at stem elongation is high and in many cases there are lower yields from delayed applications compared to N applied at sowing... Experiments over many years have shown that there is no consistent difference in the response to different forms of N fertiliser when compared at the same rate of N and the same time of application... Recent work from Victoria suggest losses of N from volatilisation of up to 1% per day with urea and about half that for UAN and ammonium sulphate (Table 1)...
