While some of the world's most productive agriculture is on artificially drained soils, drainage
is increasingly perceived as a major contributor to detrimental off‐site environmental …

No tillage (NT) has been proposed as a practice to reduce the adverse effects of tillage on
contaminant (eg, sediment and nutrient) losses to waterways. Nonetheless, previous reports …

Balancing the amount of N needed for optimum plant growth while minimizing the NO3 that
is transported to ground and surface waters remains a major challenge for everyone …

A long-term poultry manure fertilizer study was initiated in 1998 and continued until 2009
under corn-soybean (CS) rotation. To match changing landscape trends, the plots were …

Subsurface drainage of gravitational water from the soil profile through tiles is a common
practice used to improve crop production on poorly drained soils. Previous research has …

The soils and the climate of the Great Lakes and Cornbelt states dictate that drainage is
required to carry out economically viable farming activities. When drained, the soils are very …

There is a lack of quantitative information describing the impact of farming on water quality at
the watershed scale. This study documents the surface water quality of Walnut Creek—a …

No tillage (NT) is often presented as a means to grow crops with positive environmental
externalities, such as enhanced carbon sequestration, improved soil quality, reduced soil …

Publisher Summary This chapter focuses on the linkage between subsurface tile drainage of
agricultural lands and nitrate in surface waters, and the effect of uncontrollable factors and …

Subsurface drainage, a water management practice used to remove excess water from
poorly drained soils, can transport substantial amounts of NO3 from agricultural crop …
