Abstract:
... Identification of the major factors affecting herbicide transport through macropores improves our understanding of preferential flow and aids in the development and use of macropore-flow models, such as the Root Zone Water Quality Model (RZWQM). Recent research suggests that macropore-flow breakthrough time (bt) and the number of percolate-producing macropores (nmacro) affect herbicide concentrati ...

Abstract:
... Herbicide detection in surface water sources has caused concern about contamination of these sources and adverse effects on human and aquatic health. Understanding surface water herbicide transport from agriculturally intensive watersheds is useful for development of herbicide best management practices to reduce off-site movement. The seasonal occurrence and load of five herbicides exported by a s ...
