Soil nutrient values in units of "years of use" rather than units of ppm

The #MLSN method for nutrient recommendations involves an MLSN value that the soil is not supposed to drop below. But what does this value mean, when converted from the usual units of ppm (mg/kg) to how many years it would take grass to use that much of the element?

What is The ATC Doublecut with Micah Woods?

I discuss ATC blog posts, with supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.
