In 1994, a maximum of three liming treatments (combinations of Ca, Mg, P, K, N) were spread on plots with, most often, three replications (118 plots, controls included) in Beach (5), Oaks (2) and Spruce (5) tands of the Ardenne. Crowns health status is evaluated each year and chemical composition of soils and foliage is analyzed periodically.
