Effects of residue placement and crop type on residue C and N addition, recovered in coarse fragments (>2 mm), and losses during the crop growing period in the greenhouse.

*Significant at P = 0.05. **Significant at P = 0.01. *** Significant at P = 0.001. aIncludes C and N added from the residue application and leaf fall. bNumbers followed by different letters within a column in a set are significantly different at P≤0.05 by the least square means test. cCoefficient of variation. dNot significant.
