  • No rain, one boar, and 40 years of summer precipitation
    2026/08/21

    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).

  • Phosphorus, rootzone volume, and algae
    2026/08/11

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

  • When the soil report is not really about extractable vs. available nutrients
    2026/08/03

    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/

  • Stressed turf and nutrient supply
    2026/07/29

    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.

  • What happens to sand particle sizes after topdressing
    2026/07/20

    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.

  • Wet air, summer, and dew point depression
    2026/07/13

    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.

  • Putting green firmness and surface organic material (OM246)
    2026/07/06

    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.

  • Sand topdressing matched to clipping volume, with Bjarni Hannesson
    2026/06/01

    I've updated my recommendation for the sand quantity to apply for every unit of clipping volume harvested, if your goal is to keep surface organic material constant. Bjarni and I discussed topdressing by this method and the new equation that finds this sand amount.
