Preferential flowpaths and fertilizer placement influence subsurface P transport across soil textures and seasonal conditions
(University of Waterloo, 2018-12-14)Agricultural tile drains are a source of phosphorus (P) contributing to eutrophication. Preferential flowpaths can rapidly transport P to tile drains, but their activation in different soil textures and under variable ...
