“…Before planting and during crop growth, wet soils limit field operations such as tillage, fertilization, and pesticide application. This is a major challenge because the need for these practices is often greater in wet soils 10,11 . Poor field trafficability can also delay planting, which has a direct negative effect on yield potential due to a reduction in growing degree days 12 .…”

Artificial drainage is among the most widespread land improvements for agriculture. Drainage benefits crop production, but also promotes nutrient losses to water resources. Here, we outline how a systems perspective for sustainable intensification of drainage can mitigate nutrient losses, increase fertilizer nitrogen use efficiency (NUE) and reduce greenhouse gas emissions. There is an immediate opportunity to realize these benefits because agricultural intensification and climate change are increasing the extent and intensity of drainage systems. If a systems-based approach to drainage can consistently increase NUE while maintaining or increasing crop production, farmers and the environment will benefit. Disciplines

“…Based on average landscape slope (Table 1), these watersheds can be grouped into two categories: (1) low relief (Minnesota River, Blue Earth River, Cottonwood River, Illinois River, Embarras River, and Maumee River), and (2) moderately steep (Grand River). This grouping is important considering that low relief watersheds are extensively tile drained; resulting in a large proportion of the precipitation percolating through the soil and carrying with it the soluble nitrogen (Beauchamp 1987;Strock et al 2018). Comparatively, in moderately steep watersheds, a large proportion of the precipitation runs off as overland flow resulting in less water percolation and thus less soluble N loss.…”

Research Impact Statement: Recent increases in river N-loads in the Midwest United States are primarily caused by wet climate. Under current cropping systems, tile-water remediation will be necessary to reduce river N-loads.ABSTRACT: Nitrogen (N) losses from agricultural lands in the Midwest United States are contributing to the expansion of the hypoxic zone in the Gulf of Mexico. This study evaluated the importance of inter-annual variability in precipitation, land cover, and N fertilizer use on NO 3 + NO 2 -N loads in seven United States Midwestern Rivers using the backward stepwise regression analysis. At the annual scale, fluctuations in the current and previous years' precipitations explained much of the variation in streamflow, baseflow, and N-load. Previous years precipitation effects were associated with fillable soil porosity. In some years, higher residual soil N from previous dry years also contributed to an increase in N-load. Area under soybean production (SOY), a surrogate for replacement of prairies and small grains was generally not a significant explanatory variable. Fertilizer use from 1987 to 2012 was also not a significant explanatory variable in the annual analysis. Precipitation in both the current and previous months and previous year were important in explaining variation in monthly streamflow, baseflow, and N-load. SOY was significant in one or two months from June to August, but had a higher pvalue than precipitation. We conclude recent increases in river N-loads are primarily due to wet climate and minimally due to the changes in land cover or N fertilizer use. Under current cropping systems and agronomic N application rates, tile water remediation will be necessary to reduce river N-loads.(

“…These challenges stress the need to enhance research that integrates sensor-based data and management technologies toward achieving sustainability goals of maintaining agroecosystem services (increased production, reduced environmental impacts) while addressing water scarcity at technological (developing alternative water sources, reducing energy costs) and societal (inter-sector competition for water) levels. An excerpt from the recent ASABE drainage collection (Strock et al, 2018) captures the grand challenge for agricultural drainage research as an integrated agroecological and socio-economic issue:…”

Abstract. This article highlights current research into land and water resources, agroecosystems, and agricultural production systems published by the Natural Resources and Environmental Systems (NRES) community of ASABE journals ( and ) in 2017. Context, scope, and key results of the published articles are reviewed and perhaps more importantly areas for increased research attention are recommended. This article describes experimental and modeling advances in hydrology, agroecosystems, climate change effects, soil erosion, agricultural irrigation, agricultural drainage, forest resource management, livestock systems, natural treatment systems, international water issues, and water quality topic areas. Three special collections were published (International Watershed Technology, Crop Modeling and Decision Support for Optimizing Use of Limited Water, and Advances in Drainage). Other focal areas included 14 articles relating to livestock waste management, 13 concerning irrigated agricultural systems, 8 addressing climate change effects on land, water, and agroecosystems, and 16 on various aspects of soil erosion measurement and modeling. Building on the articles reviewed from 2017 and toward a vision of future agroecosystems research, the NRES community of ASABE journals strives to expand its role in making new knowledge accessible to sustain agricultural and natural systems in a changing world. With this goal in mind, recommendations for future research needs are proposed with an emphasis on increased application of remote sensing data to agroecosystems research, improved assessment of agroecosystem resiliency and vulnerability to land and climate change, development of integrated models of agroecosystem services, meeting stubborn water management challenges in agricultural production systems, and focusing on publishing fully reproducible model results.
