Responsibilities and Interests:
My specialization focuses on the effects of soil management practices on soil physical properties and processes. This includes the effect of no-tillage and tillage on soil physical properties, how soil compaction affects soil and crops, what effect crop rotation plays in maintaining soil quality, and the benefits and challenges of cover crops. The use of a systems approach to no-tillage, soil compaction and crop rotations is a crucial element in all my work. Research takes place on Penn Stateís research farms as well as in collaboration with farmers and field agronomists in Pennsylvania.
