Lack of adequate soil volume is the primary factor limiting root growth and thus tree canopy growth in developed sites. Clearly bigger is better: the more penetrable soil volume available to a tree, the more rapidly and ultimately larger it will grow. However, soil amendment and modification techniques are difficult and poorly described in a readily accessible way for those in the field. Landscape managers and arborists need a manual that will allow them to assess a soil’s ability to support root growth coupled with multiple strategies for ameliorating that soil. We will modify some of the newest soil health information now available to farmers for application in the built landscape. The end product will be a manual that describes a field applicable soil assessment process with a range of soil modification techniques graphically represented.
