Excessive salts in soil can restrict a plant’s water and nutrient uptake, hindering crop growth and reducing yields on roughly 30% of U.S. irrigated land. To help growers identify and mitigate salt stress, in a proof-of-concept study, a team led by Penn State researchers built a low-cost sensor sy...

It has been a while since I shared updates on our work - it has been a very busy season - we are continuing to work on a lot of fronts and technologies/solutions.
Here I am sharing pictures from a series of Extension/Outreach events that engaged everyone working in the lab, and especially the graduate students and postdoc, who, over the last few weeks, have not missed a single opportunity to share and communicate in various forms and to different audiences all the great things we are working on.

For Penn State Ag Progress Days, a 3-day event, we prepared an exhibit on Plasma Agriculture, we offered daily tours of our research on organic vegetable production, and organized an in-depth 2-hour workshop + research tour for the PA Organic Agriculture Working Group.

Last week, for National Teach in Ag Day, we participated in the Plant Yourself in Ag project and shared our research and engaged in different ways with groups of high school students, attempting to inspire them to pursue a career in agriculture.

Today, we had the honor of sharing our work on improving the efficiency of Controlled Environment Agriculture systems, Plasma Agriculture, and Agronomic Biofortification with elected officials at the federal, state, and local levels, industry partners, and other stakeholders.

Each of these events requires a great effort; it takes a lot of planning and preparation, but all the feedback we got, the opportunity to share our knowledge, and the engagement with people interested in our work is priceless. It is also a great learning opportunity for us and gives us motivation to continue our work even when it is challenging.

For me, there is nothing more exciting than working/doing research with a team of great young scientists, learning every day, and having the opportunity to share our knowledge, inspiring people, advancing and transferring the solutions we are developing to the final users, empowering them to do more.

For this, I would like to thank the Penn State College of Agricultural Sciences for offering us the great opportunity to participate in these Extension/Outreach initiatives. I am also grateful to all our funding agencies and private partners who support our work.

Great job done by The Culinary Breeding Network and Smarties.bio introducing Radicchio to the large public - check this video:

People don’t give much thought to the purple leaves in their salad mix, but maybe they should! That bitter, leafy vegetable is likely radicchio — and it's ha...

The 2025 Mid-Atlantic Fruit & Vegetable Convention taking place at Hershey, PA last week was really intense but a great opportunity for us to share our work, meet with growers, industry professionals and colleagues and exchange information and updates. Before the conference started we had a great full-day workshop on in which we went through different aspects (production, quality, food safety, economics, marketing, and current research) bringing in the expertise of researchers, microgreen growers, crop consultants, and extension educators. During the three-day convention different members of our lab and some of our collaborators had the opportunity to present our work in different sessions, including the Soil Health, Hydroponics, Vegetable Greenhouse, and two High tunnel sessions, which resulted in over 10 presentations... We also had the opportunity to invite multiple vegetable growers and colleagues to share their experience through presentations or grower panels. We made multiple connections and left the convention with renewed energy and motivation to continue our work at Penn State College of Agricultural Sciences with the support of Pennsylvania Vegetable Growers Association
