Present research is attempting to provide more answers. Early indication of some research indicates less potential for groundwater contamination with conservation tillage compared to conventional tillage. More research is needed to provide answers on how to adapt the various kinds of conservation tillage to a groundwater quality program. Grass Filter strips Grass filter strips along field edges can trap pesticides to prevent surface water contamination. Similar strips around sinkholes or agricultural drainage well surface inlets can reduce contamination of groundwater.
Filter strips can also serve to reduce erosion and compaction of equipment to and from a field.
