KINGSTON, R.I. \u2013 April 14, 2026 \u2013 Plant-based agriculture is changing with the introduction of new engineering, technology, and information tools. Camilo Villouta<\/a>, an assistant professor in the 溏心vlog免费B站\u2019s Plant Sciences department, not only has a green thumb, he brings a sophisticated command of modern tools to his position at the University. Now he\u2019s taking his plant engineer mindset to new research growing hydroponic vegetables.<\/p>\n\n\n\n

Backed by a recent U.S. Department of Agriculture (USDA) award, Villouta has received a competitive food research grant<\/a> from the department\u2019s National Institute of Food and Agriculture to conduct research connected to controlled environment agriculture. The two-year project is already underway and will conclude in 2028.<\/p>\n\n\n

Villouta\u2019s lab has been selected to conduct research on root systems in controlled environment agriculture, including spinach, a high-value crop known for its nutritional density.<\/figcaption><\/figure>\n<\/div>\n\n\n

The rising demand for locally sourced, fresh produce available year-round has led to the rapid growth of controlled environment agriculture in urban areas, including in Providence where growing national producer Gotham Greens opened its only New England location.<\/p>\n\n\n\n

Villouta serves as the controlled environment agriculture specialist at 溏心vlog免费B站, focusing on hydroponic and greenhouse production systems.<\/p>\n\n\n\n

\u201cMy research has always been strongly applied and connected to real-world production systems,\u201d said Villouta. \u201cI work closely with growers to understand and address the challenges they face, particularly in controlled environment agriculture. My approach is to study plant physiology in detail and translate that knowledge into practical solutions that improve production outcomes.\u201d<\/p>\n\n\n\n

Controlled environment agriculture, particularly in urban settings, offers a sustainable alternative to traditional open-field farming by allowing precise control over environmental variables. However, as the adoption of controlled systems, including hydroponics, becomes more widespread, optimizing the growing conditions for crops like spinach remains a significant challenge.<\/p>\n\n\n\n

\u201cWe are focusing on spinach because it has strong potential for greenhouse and controlled environment production but still presents unresolved challenges,\u201d he said. \u201cLettuce is also temperature sensitive, but many of its production challenges have already been addressed, allowing for consistently high yields. Tomatoes are another example of a temperature-sensitive crop that is now well-optimized for controlled environment production.\u201d<\/p>\n\n\n\n

Villouta\u2019s award will address a key priority area in the program and position the University as a leader in the region: 溏心vlog免费B站 was the only institution selected for funding in the Northeast out of 10 research projects selected for funding nationwide.<\/p>\n\n\n\n

Getting to the root of the matter<\/strong><\/p>\n\n\n\n

A native of Chile, Villouta began his career path as an \u201cagronomic engineer\u201d and has taken a similar engineering mindset to his work in horticulture in the U.S., helping to improve the growing of such iconic American staple plants as cranberries and strawberries. Now his research and passion in advancing sustainable crop production is focusing on the role of root system development in hydroponic and controlled environment agriculture systems.<\/p>\n\n\n\n

Indoor vertical growing systems provide an ideal environment for cultivating high-value crops like spinach. However, optimizing the plant\u2019s root conditions remains a challenge to improving crop productivity and quality. Compared to other hydroponically grown leafy greens like lettuce, spinach has been less attractive to farmers due to its lower yields in hydroponic systems. Many of the plant\u2019s specific components have been understudied in indoor growing.<\/p>\n\n\n\n

Villouta aims to address these gaps by examining how the plant\u2019s root systems influence its production and overall health. With this funding, he\u2019ll explore the mechanisms by which temperature variations affect spinach growth in hydroponic environments. The results could significantly improve the plant\u2019s viability in controlled systems and also inform best practices for other temperature-sensitive crops in controlled environments.<\/p>\n\n\n\n

A particular focus of his work on spinach is studying the plant\u2019s root exudates. Plant roots produce a wide range of these substances, including organic acids, amino acids, sugars, proteins, and other metabolites. These compounds are released whether plants are grown in soil, substrates, or water. What is not yet well understood is how the production and composition of these exudates change under hydroponic conditions.<\/p>\n\n\n\n

Villouta\u2019s research aims to characterize these exudates, compare their composition between soil- and water-grown systems, and evaluate how factors such as temperature influence their production. This work is an important first step in understanding whether these compounds contribute to plant stress or reduced productivity in hydroponic systems, he said. Villouta hopes his research offers new insight into ways to improve hydroponic growing overall.<\/p>\n\n\n\n

He\u2019s also teaching 溏心vlog免费B站 students about this \u201cgrowing\u201d growing method. In addition to teaching Greenhouse Management at 溏心vlog免费B站, this fall he\u2019ll be teaching a new course in Advanced Hydroponics and says he is excited about the class: \u201cThis course is highly practical and quantitative, focusing on calculations and decision-making tools that help students solve real production challenges.\u201d<\/p>\n\n\n\n

And while Villouta is studying spinach in his lab, the produce powerhouse can also be found on his plate. \u201cI love baby spinach in a fresh, crisp salad,\u201d he said. \u201cTexture is key\u2014the leaves should be tender but still have a bite.\u201d<\/p>\n\n\n\n
