A continuous improvement system for turfgrass

These are the slides I used for a presentation in Cavite, Philippines.

Regular measurement of soil nutrients and soil organic matter content allows turfgrass managers to adjust the nutrient supply and the organic matter management—sand topdressing, cultivation, and verticutting. These adjustments, when implemented, cause two inevitable results. One is improved turfgrass conditions. This comes from eliminating nutrient deficiencies, supplying the turf with all the nutrients required, and adjusting the soil organic matter for improved playability. The second inevitable result is improved work efficiency. Applying nutrients and sand and thatch control treatments only when there is a confirmed requirement for them elimates wasted applications and unnecessary work. Basing the work on regular measurements will also identify when extra work or applications are required. These inevitable consequences result in a continuous improvement system for turfgrass management.

I should note that the inevitable results of improved conditions and better efficiency only happen when one interprets the measurements correctly. I, of course, discussed how to make an optimal interpretation of results in the seminar.
