The I.S.T.R.C. concept of developing a better understanding of the physical properties of sand-based greens, push-up greens, and athletic fields started in the spring of 1991. Working with hundreds of courses throughout the U.S., including 6 of the top 10, I.S.T.R.C. has built a strong database of information and knowledge. I.S.T.R.C.'s main objective is to provide superintendents with the information that not only identifies greens/athletic fields physical properties, but also provides the necessary information to be proactive in regards to cultural practices that affect the turf. Over the years, the premise of annual monitoring has become a staple in superintendents' programs throughout the country.
