英文摘要 | In June 2002, the Department of Energy (DOE) began establishing the 60 ha Howell Prairie at the DOE Weldon Spring Site (WSS). In one area, the clay base is different from the other soil (subarea 2C). Vegetation sampling was conducted on four permanent plots across the prairie beginning in 2008, and shows that three of the four plots have strong establishment of native prairie species including prairie grasses. The fourth plot (subarea 2C), where the soil is different, shows significantly less native grass cover and stunted vegetation compared to the other three plots. One hundred twenty-five soil samples were taken in 6 different months and in 6 different years across the entire prairie restoration. Across the prairie, potassium (K) and phosphorus (P) were not limiting. The pH, organic matter content (OM), and cation exchange capacity (CEC) did not show trends related to the vegetation issues in subarea 2C. Ordination of the ratio of magnesium (Mg):K shows that Mg is very high in subarea 2C, which has been demonstrated to suppress the growth of prairie grasses. Subarea 2C contains interstratified kaolinite-smectite clay which contributes Mg to soil. It is hypothesized that an inexpensive, nondestructive treatment (addition of K) could be applied to remediate this area. |
