A grid lysimeter system and sample collection, containment, and storage techniques were developed for defiled laboratory studies of water and solute movement through intact soil blocks. This was done because existing designs and techniques had import

The risk of surface-water contamination by herbicides is greatest following application to cropland when the active ingredients are at the maximum concentration and the soil is the most vulnerable to erosion following cultivation. This study determin
