Michael Rosato, a graduate student studying under the guidance of Steve Reiners, professor and chair of the horticulture section of the School of Integrative Plant Science, is evaluating the soil sulfur levels on vegetable farms across New York State and conducting sulfur fertilizer trails that have economically important crops for growers.

What drew you to the program with Steve Reiners?

I first worked in Steve Reiners’s program at the beginning of my undergraduate years as a summer technician. Steve always took the time to answer questions and helped me explore the world of horticulture. Beyond being a true mentor, seeing how his worked helped growers—both with sustainability and success—was a big reason why I wanted to work with him.

What’s the focus of your research?

Historically, sulfur has been abundant in soils mainly due to widespread pollution and the use of manure. In the 1970s, the creation of the Environmental Protection Agency and the Clean Air Act led to a gradual but drastic reduction in atmospheric sulfur, and thus, less sulfur was deposited in U.S. soils.

My project has two key elements. First, we are evaluating soil sulfur levels on vegetable farms across New York State, and second, we are also conducting sulfur fertilizer trials that have economically important crops for growers. We are measuring both yield and quality factors across all crops.

In our tomato trial, we are conducting sensory evaluations, as well as testing soluble solids and titratable acids to see if sulfur may be impacting flavor.

What’s the most exciting thing you’ve discovered while doing research at Cornell AgriTech?

In our first sensory evaluation, a panel of 100 participants generally rated sulfur-treated tomatoes as more acidic. Their observations were mirrored in our measurements of citric acid in the fruit.

Sulfur is a macro-nutrient that may impact the flavor of vegetables like tomato and onions, but it is often overlooked. If growers can add flavor intensity to their tomatoes by using a sulfur source like gypsum, which is cheap, easily applied and has the option of being organic, it’s a win for the farmer and the consumer.

In what ways do you hope your research will help growers in New York?

By measuring soil sulfur levels state-wide, we hope to get a better idea of how common sulfur deficiencies are. Further, we want to create accurate fertilizer recommendations for growers, so they can produce the highest quality products possible in both an affordable and sustainable way.

How do you think graduate students benefit from doing translational research?

Working on real life issues and seeing your efforts positively impact others’ lives is an important experience for all of us, and it’s truly fulfilling. I think translational research is a place where people can find purpose in helping others in any variety of ways.
