      abstract     = {Understanding the rhizodeposited carbon (C) dynamics of
                      winter wheat (Triticum aestivum L.), is crucial for soil
                      fertility and C sequestration. Pot-grown winter wheat was
                      pulse labelled with 14CO2 at the key growth stages. 14C in
                      the shoots, roots and soil was measured at 5 or 2 days after
                      14C-labelling (DAL 5/2) at each growth stage and at harvest.
                      The 14C in the shoots increased from $4\%$ of the net 14C
                      recovered (shoots + roots + soil) during tillering
                      to $53\%$ at harvest. Approximately $14–34\%$ of the net
                      14C recovered was incorporated into the soil. Allocation of
                      photosynthesized C was extrapolated from the pot experiment
                      to field condition, assuming a planting density of 1.8
                      million plants ha−1. The estimated C input to the soil was
                      1.7 t C ha−1, and 0.7 t C ha−1 of root residues was
                      retained after wheat harvest; both values were higher than
                      those previously reported (0.6 and 0.4 t C ha−1,
                      respectively). Our findings highlight that C tracing during
                      the entire crop season is necessary to quantify the temporal
                      allocation of photosynthesized C, especially the
                      contribution to soil carbon in intensified farming system.},
