In 1955, The Lawn Institute was created as a not-for-profit corporation to assist and encourage through research and education the improvement of lawns and sports turf. Since then, the Institute has been one of the most respected authorities in the world among turf professionals and scientists for monitoring, reporting, and interpreting the latest advances in turfgrass research, landscape horticulture, and agronomic science. The Lawn Institute conducts its own research program which funds some of the world's highest regarded turf scientist to fill gaps in our knowledge.
