Dry matter partitioning and residue N content for 11 major field crops in Canada adjusted for rooting depth and yield

Abstract

To improve the estimates of C and N inputs to soil, we developed new estimates of partitioning between the harvested portion, aboveground residue, and belowground residue for 11 major crops based on depth-adjusted root/shoot ratios and grain yield-adjusted harvest indices. We updated the mean N concentration of each partition.
