Spring Seminar on Glyphosate-based Herbicides Impacts
This semester we will hold a research-based multi- disciplinary seminar on reassessing the potential transport and impacts of glyphosate-based herbicides (such as the familiar product, Roundup) and their primary degradation product, AMPA. Due to the development and predominance of transgenic glyphosate-tolerant crops such as corn and soybeans, the use of glyphosate has increased markedly in recent years, and it is now one of the most heavily-used active ingredients. Its direct toxicity is very low, and post-application immobilization and degradation are rapid. However, recent research has found widespread − albeit low- level − detections in the environment in agricultural areas, while others suggest the potential for non- target adverse impact pathways. We look forward to an open discussion from many disciplinary perspectives.

New Publication on Denitrification in Stream Riparian Areas
Soil & Water Lab PhD Candidate Lauren McPhillips has recently published a paper from her Master's degree research on denitrification in stream riparian areas. Lauren found that denitrification was controlled by groundwater flow rates through the riparian zone. Though denitrification rates were very high, Lauren also found that other important ecosystem processes are contributing to transformation or removal of excess nitrate in groundwater, including a microbial process called dissimilatory nitrate reduction to ammonium (DNRA).

New Research Article on the Impact of Conservation Practices on Runoff and Soil Loss in Ethiopian Highlands
Soil & Water Lab professor Tammo Steenhuis together with Bahir Dar University PhD Candidate Dessalegn C. Dagnewand and Cornell PhD Candidates Christian Guzman, Assefa Zegeye, and Tigist Tebebu published results from a four year project monitoring the impact of conservation terraces with infiltration furrows on stream sediment concentrations and runoff volume in the Debre Mawi Watershed in Ethiopia. Runoff volume decreased, but sediment loading decreased only marginally during the main rainy season. In flat bottom lands where monsoon rains saturated the soils seasonally, the conservation furrows initiated gully formation.

Lunch is provided.
Soil & Water Lab Professors Tammo Steenhuis and Gail Holst-Warhaft along with journalist Francesca de Chatel, recently edited a book on transdisciplinary water work in the Mediterranean. An excerpt from the forward highlights the water resource challenges of this region and the editors' hopeful perspective on sustainable solutions:
The Mediterranean is among the most arid regions in the world. Hosting more than 50 percent of the world's 'water poor' population, or around 180 million of the region's 460 million inhabitants, the Mediterranean holds only 3 percent of the world's freshwater resources. To meet water scarcity problems, Mediterranean peoples have throughout history transformed this challenge into a driver for innovation and social organization. Hopefully their capacity for adaptation and their creative imagination will allow them to address the growing challenges, also in the future.
The Mediterranean is endowed with natural beauty, rich biodiversity, and fertility. It hosts a fast-growing and young (on the southern and eastern shores) population, which has over recent decades adopted unsustainable consumption patterns. The region experiences high anthropogenic pressures from rapid urbanization, tourism, industrial and agricultural development among others, while climate variability and change, in addition to desertification, pollution and loss of biodiversity, form growing threats. Furthermore, the Mediterranean region as a whole currently faces a deep socio-political and economic crisis.
Mediterranean societies strive to ensure sustained economic growth, human security and political stability. In order for this to succeed, the integrated management of water, energy, food and environment has to become a priority issue for governments, societies and business.
The full book, Water Scarcity, Security and Democracy: a Mediterranean Mosaic, can be downloaded for free here. This project was supported by the Global Water Partnership Mediterranean, Cornell University and the Atkinson Center for a Sustainable Future.
Studying Sediment Transport in a Reforested Cauca Valley
As part of the NSF GROW/USAID Research and Innovation Fellowship program, Christian Guzman is working on developing a watershed hydrology sediment transport study in several watersheds of the Cauca Valley under the guidance and mentorship of researchers from the Soils Research Group in the International Center for Tropical Agriculture (CIAT). This anticipated partnership will build on the collaboration between Ecoaguas syngenta, Asobolo, and Asofrayle (water use associations in Rio Bolo and Rio Frayle) and the Nature Conservancy in their efforts to monitor the positive changes gained from implementation of conservation programs, including reforestation and enclosure.
The directors and engineers of Asofrayle and Asobolo hosted a trip to several micro-watersheds to demonstrate the programs that have been set in place and for the purpose of selecting pilot watersheds for assessing the conservation impacts. Christian's work anticipates furthering understanding of the erosion and nutrient depletion processes by small and large scale hydrological mechanisms.
Investigating Water Quality Basin Function in a Green Infrastructure Bioswale
Lauren McPhillips and undergraduate assistants were busy measuring and monitoring the effectiveness of a stormwater green infrastructure project on Cornell Campus this summer. A collaboration with colleagues from the Landscape Architecture Department led to some interesting findings about stormwater basin function. The bioswale at the Cornell Plantations Nevins Center collects and filters water from a small parking lot and grassed field, reducing annual stormwater runoff from the site by 31%. Bioswales are often prescribed for reducing nutrient loading, however Lauren's monitoring found the basins to be a net source of dissolved nitrogen and phosphorus. Old topsoil and enriched mulch are suspected as sources of nutrient leaching. The bioswale performed well in reducing metals in runoff. To read more on the work and methodology check out the report on the Landscape Architecture Foundation's website, a major supporter of the project.
Predicting Saturation-Excess Runoff in the Northeast
A recent publication from Lauren McPhillips, S&W Lab Alumnus Anne Elise Creamer, postdoctoral
researcher Brian Rahm and Professor Todd Walter investigated methane concentrations in drinking water wells in Chenango County. Methane
concentrations in water wells near conventional natural gas wells was found to fall within federal guidelines. The dissolved methane distribution in the county is
driven by hydrogeology and geochemistry.

Growing bioenergy feedstocks can provide a long-term sustainable production system for marginal land resources and is essential for minimizing food vs. fuel competition for prime croplands. However, the term ÂmarginalÂ is too often used in research reports without being defined. We here suggest that clearly specifying the biophysical factors and agroeconomic context contributing to marginality will greatly enhance the utility and comparability of published research.

Our lab is recognized for outstanding achievements in mission integration. This involves
implementation of a program or project which incorporates, in a meaningful way, full integration
of research, education, and extension and exhibits an understanding of the complementary
nature of these three functions.
The CSREES annually recognizes exemplary work from a team at a land-grant university or
other cooperating institution or organization supported by CSREES.
This program will allow recognition of outstanding contributions in support of the USDA
mission as part of the strategic goals of the Cooperative State Research, Education, and
Extension Service (CSREES).
