Simulation setup in respect of crop sowing conditions and fertiliser
applicationwas adopted fromYang et al. (2014). Briefly, similar
to current farming practice (GRDC, 2005; Heenan et al., 1994; Hunt
and Kirkegaard, 2011), a standard sowing window was considered
from 1st April to 31st July and sowing to germination was
dependent on soil water status driven by autumn rains in any day
between 1 April and 31 July.
