Viticulture at the Long Island Horticultural Research and Extension Center

Suffolk County is leading New York State in the market value of crops that are produced. It is the top region in New York State for the sale of nursery, greenhouse, floriculture and sod products, and it accounts for half of all statewide sales in these products. The almost 600 farms remaining in Suffolk County are covering more than 34,000 acres.

Agriculture on Long Island is thriving, because:

  • It has plenty of fresh water available for irrigation from a single underground aquifer
  • The weather is ideal for farming: USDA Plant Hardiness Zone 7
  • It has high light intensity for crop growth
  • The sandy loam soils are excellent for cultivation
  • One of the world’s largest markets, New York City, is only about 100 miles away

Cornell University has been serving the agricultural industries in Suffolk County since 1922 and has leadership and extension professionals in all areas of crop agriculture (vegetables, fruits, grapes, floriculture and greenhouse, nursery and landscape) as well as in entomology, plant pathology, weed science and plant tissue culture. It is the only research center in the United States of its kind.
