Deep row entrenchment of biosolids using hybrid poplar

Event information

Date

Add to Calendar 2021-10-19 10:00:00 2021-10-19 11:00:00 Deep row entrenchment of biosolids using hybrid poplar Jonathan Kays, Forestry Extension Specialist, University of Maryland Extension, will present on the Deep Row Entrenchment (DRE) of biosolids using hybrid poplar. Biosolids, formerly known as “sludge,” refer to the residual materials removed from sewage during the wastewater treatment process. Biosolids are commonly applied to land for beneficial utilization, but it has become increasingly difficult to apply these biosolids on land. This is due to nutrient management regulations, accelerating land prices, the disappearance of farm land, and social issues surrounding odors. The utilization of biosolids using short rotational crops of hybrid poplar trees solves many of the problems associated with traditional biosolids application methods and holds great promise. Deep row entrenchment (DRE) is a biosolids beneficial reuse system that uses a one-time application of biosolids in wide and shallow trenches covered with overburden, and planted with hybrid poplar cuttings. Years of research by Gary Felton, water quality specialist, and Jonathan Kays, on a gravel spoil in southern Maryland demonstrated minimal impacts on water quality and revealed how this beneficial reuse system is best applied on gravel and coal strip mines for reclamation.
