Article Synopsis
- In June 2002, the DOE started a prairie restoration project at the Weldon Spring Site, focusing on a 60 ha area where soil types varied, particularly in subarea 2C.
- Vegetation sampling since 2008 indicated strong growth of native species in three plots, while subarea 2C struggled with lower grass cover and stunted plants, linked to high magnesium levels in the unique soil there.
- To address these growth issues in subarea 2C, researchers suggest using an inexpensive treatment, adding potassium, to potentially enhance the prairie grass growth in that region.
