Best management practices have been recommended for controlling nutrient, herbicide, or
sediment losses with surface runoff. This study was designed to determine the best overall …

The North Appalachian Experimental Watershed near Coshocton, OH was established in
1935 to develop, evaluate, and refine conservation practices that reduce runoff and erosion …

Tillage and weed control methods affect hydrology by altering soil surface conditions. The
objective of this study was to assess the effects of herbicide banding with interrow cultivation …

Agricultural source pollution of water resources has been a source of concern in recent
years. Research is needed to define mechanisms of chemical and sediment loss in runoff …

The presence of detectable concentrations of pesticides in surface water has caused some
concerns about possible effects on human health and aquatic biology. Herbicides are the …

Soil conservation tillage systems, including ridge‐tillage, often reduce surface water
contamination by pesticides because soil erosion and surface runoff are reduced. However …

Sediment, phosphorus and nitrogen were monitored in surface runoff and tile flow from
approximately 4-ha watersheds subjected to a conservation tillage treatment (chisel plow) …

A natural rainfall study was conducted to evaluate the effect of tillage and herbicide
application methods on crop residue cover, surface runoff volume, erosion, and herbicide …

This study quantified the effects of tillage (moldboard plowing [MP], ridge tillage [RT]) and
nutrient source (manure and commercial fertilizer [urea and triple superphosphate]) on …

Raised wide beds have been proposed as a conservation tillage practice for reducing
erosion losses in vertisols, but few measurements of nitrogen (N) and phosphorus (P) losses …
