Minimum Level for Sustainable Nutrition
Increased economic and environmental pressures have caused many of you to re–assess the way you manage turf. With fertilizers as one of the bigger inputs, we felt that it was time to review and revise our current soil guidelines.
Working together with Dr. Micah Woods of the Asian Turfgrass Center, we reviewed data on all key soil nutrients from thousands of turf soil samples, and determined that in many cases, guidelines could be safely lowered without a dramatic impact on turf quality or playability.
The result of our efforts is the new "Minimum Level for Sustainable Nutrition" (MLSN) soil guidelines, a new, more sustainable approach to managing soil nutrient levels that can help you to decrease inputs and costs, while still maintaining desired turf quality and playability levels.
