The effects of poplar (P. trichocarpa × deltoides) on soil biological properties in a silvoarable system


A silvoarable experimental site in Buckinghamshire, England combined rows of poplar trees with an arable rotation. Soil properties were investigated using soil carbon and the bodysize of invertebrates. Four years after establishment, the soil within and 1 m from the tree rows has significantly higher soil organic matter and invertebrate populations. These effects do not extend far beyond the crown diameter.
