Litter Controls Earthworm-Mediated Carbon and Nitrogen Transformations in Soil from Temperate Riparian Buffers

Table 5

Correlations between C and N losses via gaseous flux or in leachates and ancillary soil measurements, averaged from measurements ( = 144) taken at regular intervals during a 20 wks incubation study from microcosms filled with riparian soil with earthworms. Values are Spearman’s rank order coefficients (), with , , and indicating significant correlations at , 0.01, and 0.001, respectively, and NS = nonsignificant correlation.
