Soil improvement: an efficient way to restore the fertility of forest ecosystems
Subject to numerous stresses, forest ecosystems sometimes experience dysfunctions that may ultimately lead to their decline. A variety of symptoms may be observed: the yellowing of leaves or needles, a reduction in leafing, or the drying of young shoots, etc. There are many possible causes, one of which is poor stand nutrition. The INRA Research Unit for Forest Ecosystem Biogeochemistry in Nancy, working in partnership with Gessofor, can now propose an expert assessment of any soil improvement requirements in forests.
