Our Team

The Nutrient Management Spear Program (NMSP) was initiated in August 2000 when Quirine Ketterings joined the faculty of the Department of Crop and Soil Sciences at Cornell University as assistant professor of nutrient management in agricultural systems. The NMSP and its applied research and extension mission in field crop nutrient management relocated to the Department of Animal Science in July of 2008.

Key collaborator in the NMSP is Karl Czymmek, PRO-DAIRY's senior extension associate in nutrient management. Greg Godwin research support specialist, joined us in August of 2002. Greg carries responsibilities for our field-based research program. Sheryl Swink joined us as program support specialist for the NY Starter P Project in the fall of 2002 and is currently working on statewide, region and county-based nutrient balances. Sanjay Gami, research associate, joined our team in December of 2008 to support and lead laboratory-based projects. He is in charge of laboratory analyses and management.

We currently have six postdoctoral researchers in our team. Melanie Soberon, joined us in 2012. She is working with us on the whole farm mass balance project. Sebastian Cela, joined us in July 2013. He lead our projects on whole farm nutrient mass balance assessments and re-evaluation of the New York Phosphorus Runoff Index. He returned to Spain in July 2015 but continues to work with us on the New York Phosphorus Runoff Index project. Pilar Berenguer joined us in September of 2013 and works on a project on temporal and spatial variability of the corn stalk nitrate test. She returend to Spain in July 2015 where she continues to work on a journal publication on the project. Amir Sadeghpour joined us in February of 2014 and leads our project on greenhouse gas emissions from manure, compost and fertilizer managemend corn, alfalfa and grass systems. Aristotelis Tagarakis joined us in July 2014 and leads our precision agriculture program. Steve Crittenden joined in July of 2016, taking the lead on our whole farm nutrient mass balance program and re-evaluation of the New York Phosphorus Runoff Index.

Lisa Fields, independent consultant, writes student and project impact stories for us and collaborates on various other projects with us as well. We contracted with Peter Barney, who retired from Cornell Cooperative Extension of St. Lawrence County in December of 2007, for on-farm projects in St. Lawrence, and with Tom Kilcer, who retired from Cornell Cooperative Extension of Rensselaer County in June of 2009, for projects in eastern New York.

We currently have two graduate student in our program: Emma Long and Sarah Lyons. Emma graduated with a B.Sc. degree in Agricultural Sciences from Cornell University. She is a certified crop advisor working with Agrinetix on a project that aims to evaluate the performance of forage yield monitors for whole farm analyses and on-farm research. Our new graduate (PhD) student, Sarah Lyons, joined us in August of 2015 to work on production (agronomic practices) and feeding of alternative forages including winter cereals such as cereal rye and triticale, and brown midrib forage sorghum. We also work with Keenan McRoberts (recent PhD graduate in Animal Science; main advisor Debbie Cherney) and Jeff Liebert (current MS student in Soil and Crop Sciences; main advisor Matt Ryan) on field crops related project, including image-based assessment of biomass of cover crops with Keenan and the tradeoffs between yield and quality of double crops grown for forage with Jeff.

We greatly enjoy working with undergraduates, through independent research projects, work-study programs, and internships. Currently we have six undergraduates in our program: Rachel Breslauer, Andrew LeFever, and Zhenan Tang (Agricultural Sciences majors), Dennis Atiyeh (Agricultural Sciences and Animal Science double major), Isaac Cornell (Animal Science major), Elsa de Becker (Plant Breeding major). We welcome interns from other SUNY school as well!. Our most recent interns from SUNY Cobleskill were Eun Hong and Joseph Foster.

A major role in the program is played by Cornell Cooperative Extension Field Crops Educators.
