One way to manage invasive plants? Manage soil nutrient levels closely

A new study suggests that soil nutrient profile may have a major impact on changes in plant population, particularly the encroachment of invasive species. The study finds that at low nitrogen levels, native species can effectively compete, while the plant community is most susceptible to invasion and fire frequency at high nitrogen levels. Managing nitrogen availability to plants will thus be a crucial consideration for a farm or other ecosystem, and the answer to preserving biodiversity.
