Immobilizing nitrogen to control plant invasion

摘要: Increased soil N availability may often facilitate plant invasions. Therefore, lowering might reduce these invasions and favor desired species. Here, we review the potential efficacy of several commonly proposed management approaches for to control invasion, including C addition, burning, grazing, topsoil removal, biomass as well a less frequently approach availability, establishment species adapted low availability. We conclude that many be promising by stimulating immobilization, even though most are generally ineffective removing from ecosystems (excepting removal). addition removal reliable over invasive species, but too expensive or destructive, respectively, applications. Less intensive approaches, such establishing low-N grazing than lower if they produce high C:N tissue, thus stimulate immobilization. Regardless method used, sufficiently invasion will difficult, particularly in sites with atmospheric deposition agricultural runoff. where feasible, disturbances result should limited order nitrophilic weeds.
