This citizen science research project will have a big and positive effect on the way we think about and practice turfgrass fertilization. This builds on the minimum levels for sustainable nutrition (MLSN) guidelines that we introduced in 2012, now giving the opportunity for turfgrass managers from around the world to participate in this ongoing and exciting research project.
The Global Soil Survey is designed to produce and refine a new set of soil nutritional guidelines for turfgrass. These guidelines are developed to identify the lowest nutrient levels needed to support the desired levels of turf quality and playability. The MLSN guidelines are already being used at hundreds of golf courses to great success. With the Global Soil Survey, these guidelines will get even better.
