MLSN Guidelines: The scientific basis
The MLSN (Minimum Levels for Sustainable Nutrition Guidelines were introduced in 2012, and since then, have helped turf managers reduce fertilizer inputs without a loss in turf quality. Superintendents and academic who have evaluated the guidelines are profiled in these articles.
The scientific basis for the MLSN guidelines has just been published in the journal, Applied Turfgrass Science in the article, "Minimum Levels for Sustainable Nutrition" by Drs. Larry Stowell and Micah Woods. The full text of the article can be seen here.
A 15 minute presentation by Dr. Stowell at the Crop Science Society of America annual meeting in 2014, entitled "Only What the Turf Needs: Updating the Minimum Levels for Sustainable Nutrition (MLSN) Guidelines" can be heard here.
If you want to put the MLSN guidelines into place at your facility, consider taking part in the Global Soil Survey, a citizen science project sponsored by PACE Turf and the Asian Turfgrass Center that provides customizes MLSN guidelines for site specific conditions.
