Long Island Horticultural Research and Extension Center (LIHREC)
The 68-acre facility is dedicated to serve the research and extension needs of the horticulture industries of Long Island. The facility features agricultural fields and research plots, state-of-the-art greenhouses, a nursery and container production area, and a plant tissue culture facility in support of research projects ranging from grape and vegetable production, to ornamentals and floriculture.
LIHREC is located close to the tip of Long Island, in the heart of Suffolk County. Unique growing conditions on Long Island provide exceptional opportunities for this region. The climate is ideal for farming — it is the only area in New York State with USDA Plant Hardiness Zone 7. Strong underground aquifers provide plenty of fresh water.
But the reputation of Suffolk County's agriculture is literally rooted in its characteristic white, sandy soils.
Serving the community for over 100 years
Established in 1922, this pioneering research facility continues to serve the diverse agricultural community on Long Island. In this video, Director Mark Bridgen and Cornell scientists explain how research there supports fruit and vegetable growers and the floriculture and nursery industry with the latest production information, such as ecologically sound pest and disease management, and sustainable growing practices.
