Surface runoff and tile drainage are the main pathways for water movement and entry of agricultural nitrate into water resources. The objective of this 5-yr study was to characterize the partitioning of water flow and nitrate loss between these pathways for a humid-temperate Brookston clay loam soil under 54 to 59 yr of consistent cropping and fertilization. Cropping treatments included monoculture corn ( L., MC), continuous bluegrass ( L.) sod (CS), and a corn-oat-alfalfa ( L.)-alfalfa… 
Nitrate Loss in Subsurface Drainage from a Corn-Soybean Rotation as Affected by Nitrogen Rate and Nitrapyrin.
Data showed that fall application required a greater rate of N to optimize yield than spring and that greater fall rate often increased NO-N concentration and load in tile drainage water.
The Role of Field-Scale Management on Soil and Surface Runoff C/N/P Stoichiometry.
Shifting from inorganic fertilizer application to poultry litter as a fertilizer source resulted in increased absolute C, N, and P concentrations in stormflow and baseflow runoff.
Long-term cropping and fertilization influences soil organic carbon, soil water repellency, and soil hydrophobicity
Abstract: Long-term (58 yr) cropping and fertilization effects on soil water repellency were determined for a clay loam soil in southwestern Ontario, Canada by measuring soil organic carbon (SOC),
Effectiveness of Conservation Crop Rotation for Water Pollutant Reduction from Agricultural Areas
Highlights Adjusting nitrogen (N) fertilization rates for corn following legumes can reduce N losses. Including perennial legumes in corn rotations can reduce nitrate-N losses and improve water
Subsurface hydrology of tile‐drained headwater catchments: Compatibility of concepts and hydrochemistry
Concepts and terms used in previous multidisciplinary studies of tile‐drained aquitard‐dominated catchments (TDADC) are inconsistent and confusing. We provide a well‐defined, comprehensive conceptual


Effect of crop type and season on nutrient leaching to tile drainage under a corn–soybean rotation
Subsurface tile drainage is a significant pathway for nitrogen (N) and phosphorus (P) transport from agricultural fields. The objective of this study was to evaluate N and P loss through tile
Reducing nitrate loss in tile drainage water with cover crops and water-table management systems.
The combined use of a cover crop and water-table management system was highly effective for reducing NO loss from cool, humid agricultural soils.
Nitrate losses through subsurface tile drainage in Conservation Reserve Program, alfalfa, and row crop systems
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 often shown
Nitrate leaching to subsurface drains as affected by drain spacing and changes in crop production system.
Results of this study underscore the necessity of long-term research on different soil types and in different climatic zones, to develop appropriate management strategies for both economic crop production and protection of environmental quality.
Influence of Tillage on Nitrate Loss in Surface Runoff and Tile Drainage
A study was conducted to determine the effect of conservation (notillage and ridge tillage) and conventional (moldboard plow) tillage systems on NO j loss through surface runoff and tile drainage.
Subsurface Drain Losses of Water and Nitrate following Conversion of Perennials to Row Crops
Nitrate losses through subsurface drains in agricultural fields pose a serious threat to surface water quality. Substantial reductions in drainage losses of NO 3 -N can occur with alfalfa (Medicago
Nitrate nitrogen in surface waters as influenced by climatic conditions and agricultural practices.
Nitrate losses have been shown to be minimally affected by tillage systems compared with N management practices, and scientists and policymakers must understand these factors as they develop educational materials and environmental guidelines for reducing nitrate losses to surface waters.
