Comparison of nitrate utilisation by lupin
and wheat, with the wheat at different growth stages.
Project Summary:
Nitrogen carryover from pulses to wheat is
an economic advantage within a rotation.
However, wheat yield and quality after pulses can
be limited by the supply of nitrogen, and so the
potential profits from cropping are reduced. Pulses boost the
N supply via two pathways: (i) N from pulse
residue breakdown and (ii) the N sparing effect; where
N sparing refers to the common buildup of additional
N coming from non-residue sources. Previous work
has shown that both pathways may contribute
similar amounts of N. This project will identify strategies
to improve N carryover developed from an improved understanding of N transfer from pulses to wheat. |
