Small-scale (33 cm by 33 cm) dye experiments were performed to evaluate the spatial variation of infiltration by evaluating dye distribution within the upper 10-cm soil depth of a well-established no-till corn field. The variation of infiltration was

The application of pultry litter to cropland is based on the nitrogen needs of the crop, and such practice has resulted in excess buildup of soil phosphorus (P). Water‐extractable phosphorus (WEP) concentrations in runoff from these fields are abov

High levels of cover-crop residue can suppress weed emergence and also can intercept preemergence herbicides and potentially reduce their effectiveness. This research was conducted in continuous no-tillage corn to compare the effect of residue from a

Runoff from tomato (Lycopersicon esculentum Mill.) production with polyethylene mulch has been implicated in the failure of commercial shellfish farms in the Mid-Atlantic Region of the United States. Copper, applied in the form of copper hydroxide, i

This study was conducted to evaluate the effect of hairy vetch cover crop residue on runoff losses of atrazine and metolachlor under both no-till corn field plots and from a laboratory runoff system. A 2-year field study was conducted in which losses

Many of the variables that control transport of agrochemicals and pathogens in the field are difficult to measure because parameters such as slope, soil and plant conditions, and rainfall cannot be adequately controlled in the natural environment. Th

This study was designed to compare rates of herbicide dissipation and leaching in side-by-side microplots that have been under no-till and plow-till practices for various time periods. Microplots were established within eight field plots (0.1 to 0.25

Studies were conducted to determine atrazine sorption (partitioning), bioavailability (soil solution concentrations), and dissipation in the top 0 to 1.5, 1.5 to 3, and 3 to 5 cm of soil as a function of tillage. Paired microplots (plow-till vs no-ti

Crop residue and living vegetation in no-till fields can intercept large amounts of the pesticides applied at the time of planting. Previous studies have shown that the type of plant tissue intercepting the pesticide can affect the amount washed off

A soil core method is described for monitoring rates and extent of N-mineralization and denitrification from intact leguminous cover crops (e.g., hairy vetch) as a function of soil water content. The method also allows for estimates of N-fixation in
