Calcium is an essential element that is almost never required as fertilizer for turfgrass. This episodes explains how mass flow of Ca in the soil water creates an accumulation of Ca at the root surface.

The KBC News TV station did a profile of Keya GC greenkeeper Andrew McDaniel. Watch that (with an English language soundtrack, if necessary) and hear about the driest summer in at least 40 years (I didn't look back farther than that).

I discussed grass responding to P at establishment, but not at maturity, as a function of soil P combined with rootzone volume.

The topic of nutrient availability and extractable vs. exchangeable vs. available nutrients used to come up a lot, and I'm glad I haven't been asked this question as frequently in recent years. Fortunately, I have a long list of blog posts about this topic, and a good starting point is the one reviewed in this episode : https://www.asianturfgrass.com/post/its-not-really-about-extractable-or-available/

This episode discusses Grime's definition of stress as "external constraints which limit the rate of dry matter production" and how this is related to nutrient supply/demand/requirement for fine turfgrass.

I looked at sand particle sizes at the top of putting green rootzones, and compared those particle sizes to what is in the sand topdressing. The average results of this analysis are presented in this episode.

I looked at the temperatures and dew points for a range of cities around the world during the first month of the most recent meteorological summer. June 2026 in the northern hemisphere, and December 2025 in the southern.

The firmness of putting greens varies with the surface organic material. More organic material in the top 2 cm (0.8 inches), and greens are softer. I discuss terminology, the relationship between firmness and organic material, and what you can do about this.
