Fig. 1 Decomposition of barley and winter wheat residue, shown as mass vs. days after harvest (a and d); normalized mass (M/M₀) vs. days after harvest (b and e); and normalized mass vs. decomposition days (c and f). Symbols are means and lines represent plus or minus one SE. For a, b, d, and e there are nine observations per mean (three irrigation x three replications), and for c and f there are three observations per mean (replications)
