Impact of short-rotation willow as riparian land-use practice on soil organic carbon fractions and composition from two contiguous wetland systems in the prairie pothole region

Abstract: Evaluating the impact of land-use practices on soil organic carbon (SOC) in the Canadian prairie pothole region (PPR) is of concern due to the potential to sequester carbon and sustaining soil health. In a eld experiment, SOC content, carbon fractions, and chemical composition were assessed under short rotation willow (SRW) plantation in the marginal riparian zones of two PPR wetland sites and compared with adjacent annual crop (AC) and pasture (PA). The SOC, water extractable (WEOC), light fraction (LFOC), an… Show more

“…Compared to POX‐C and Cmin, WEOC had a weaker correlation with SOC (Figure 2), which is consistent with findings from Haney and Haney (2015) and Shahariar et al. (2022). Only a very small portion of SOM can be mobilized into the WEOC pool (Haney et al., 2012; Zsolnay & Steindl, 1991), hence WEOC might not be a reliable indicator of SOC build‐up and mineralization, at least in our system.…”

“…This interpretation is consistent with the result that cover crop management decreased the ratio of WEOC to WETN relative to its baseline (Figure S1), as microbial degradation generally decreased the C:N ratio of organic matter (Melillo et al, 1989;Zechmeister-Boltenstern et al, 2015). Compared to POX-C and Cmin, WEOC had a weaker correlation with SOC (Figure 2), which is consistent with findings from Haney and Haney (2015) and Shahariar et al (2022).
