In this video, I break down a Floratine Masterclass where Tim Cartwright discusses a common claim about calcium availability in soils. I examine the argument, the science behind calcium in turfgrass soils, and whether the explanation actually aligns with what we know from soil chemistry and turfgrass research.

If you manage turfgrass or are interested in soil testing, calcium availability, base saturation, and turfgrass fertility myths, this discussion will help you think critically about the claims often made in the industry.
