Next week I will be installing 3 Toro turf guard sensors beneath on of our greens. These wireless sensors report back to my computer, the volumetric water content, temperature and salt content of the green's root zone. As a superintendent, I enjoy being able to quantify some of these variables as it allows us to dial in the perfect growing environment. No amount of science can ever replace the art of greenkeeping. It does however, quantify some of those variables and aid in decision making when it comes to applying fertilizers or irrigating.
