Tree Root Morphology in Alley systems

This report describes the extent and distribution of Eucalyptus globulus, Pinus pinaster and Pinus radiata roots in the soil of agricultural land adjacent to tree lines. The influence of soil type and root pruning on root morphology is discussed. Soil water content and soil chemical characteristics are documented and discussed in light of the proximity to trees. The availability of this information will improve the understanding of how tree roots affect crop growth and aid in the development of competition management strategies which maximise the goals of crop production, water use and tree growth.
