What have you learned during your summer internships with Delaware County CCE?
We’re working on a project studying whole-farm nutrient mass balances, so we’re looking at all the nutrients coming onto farms, how they cycle through and how they leave farms. At CCE we go out on farm visits to collect soil samples and other information needed for the annual assessments. I input the data, and then Agustin Olivo, Ph.D. student on the project, runs a progress report that shows how the farm is doing: if they’re not using enough fertilizer and depleting their soil resources, or if they’re using more than is needed, which costs farmers money and could pose a risk for the environment. Then we go back to the farm and discuss the results with them and suggest some tweaks to their management plans.
I was working with four organic and/or grass-fed dairies to see how their management impacts nutrient cycling and soil health. I went back 30 years into the soil test database and pulled every soil sample we have for these four farms, to see how phosphorus levels have changed over time.
Another part of the project is looking at farms’ carbon footprints using the Cool Farm Tool, an online calculator that helps farmers assess greenhouse gas emissions, water use and biodiversity. The tool has mostly been used in Europe, so we’re trying to see if it can be used here in New York.
I’ve learned a lot about the scientific method, about different management strategies to help farmers maintain productivity and soil health without overfertilizing, and a lot about myself and my future career goals. For me, the hands-on experience I’ve gained has been really valuable.
The Dairy Sustainability Key Performance Indicator project that Anderson has participated in is funded by grants and contributions from Chobani, the Toward Sustainability Foundation, and the Northern New York Agricultural Development Program. Additional funding for the student summer internship program came from the Cornell Cooperative Extension Summer Internship Program, Cornell Cooperative Extension of Delaware County, and the Miner Institute.
