Soil Replacement: Long-Term Results    (View PDF)

Gary W. Watson

Abstract: Soil replacement treatments in a radial trench pattern around white oak (Quercus alba) trees, filled with compost or a compost-topsoil mix, were sampled 14 years after treatment. Root development in the replacement soils was greater than in the unmodified control soils. Root development was not increased in soils adjacent to the trenches over time as was originally anticipated.

Keywords: Root development; soil replacement; vertical mulching
