Subsurface drainage is a common practice in many agricultural watersheds in the Mid-Western region of the United States. A typical drainage system in east central Illinois is not spaced in a parallel manner, but the subsurface drain lines are laid out in a random and irregular fashion. These subsurface drain lines most often discharge into numerous man-made drainage channels, which ultimately drain to the rivers and the reservoirs. The Little Vermilion River (LVR) watershed in east central Illinois, USA is an example of a watershed with altered hydrology from subsurface drainage systems. A continuous monitoring study has been conducted from 1991 to 2003 on this watershed to quantify the effects of cropping management...
A long-term water quality monitoring program was established to evaluate the effects of agricultural management practices on water quality in the Little Vermilion River (LVR) watershed, IL. This watershed has intensive random and irregular subsurface drainage systems. The objective of this study was to assess the fate and transport of soluble phosphorus (soluble P) through subsurface drainage and surface runoff. Four sites (sites A, B, C, and E) that had subsurface and surface monitoring programs were selected for this study. Three of the four study sites had corn (Zea mays L.) and soybeans (Glycine max L.) planted in rotations and the other site had seed corn and soybeans. Subsurface drainage and surface runoff...
