Phosphorus, rootzone volume, and algae

I discussed grass responding to P at establishment, but not at maturity, as a function of soil P combined with rootzone volume.  Posts discussed are: https://www.asiant

When the soil report is not really about extractable vs. available nutrients

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 freq

Stressed turf and nutrient supply

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/dem

What happens to sand particle sizes after topdressing

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 a

Wet air, summer, and dew point depression

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 north

Putting green firmness and surface organic material (OM246)

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,

Sand topdressing matched to clipping volume, with Bjarni Hannesson

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. Bjar

Post-rain growth flush: 12 mL from water, 8 from mineralized soil N, & 2.5 from N in the rain

This is about partitioning the growth flush after a rain. What's causing that growth flush? I made some calculations, using New Forest GC in the UK as an example. The inc

More air in the soil with frequent irrigation

It sounds counterintuitive at first, that you can maintain a lower average water content in the soil, and a higher air content in the soil, by applying irrigation every d

Why you should know standard sand amounts but not necessarily copy them, with Brian Whitlark

Competition, stress, disturbance, species, strategies, and Grime

High maintenance turf often requires a high disturbance and high stress environment. Grime's CSR theory says there are "no viable strategies" for plants in such an enviro

Downward trend in OM2 and varying sand and N rates by green with T-Jay Creamer

T-Jay Creamer is the golf course superintendent at Olympic View Golf Club on Vancouver Island. He's seen a steady decrease in OM2 in response to his N and sand rates, alo

Averages, river crossings, fescue, nutrients, spot spraying, and snow mold with Jason Haines

Firmness, sand, and zoysiagrass with Stewart Naugler

Stewart Naugler is the Director of Agronomy at Loraloma in Texas. We talked about zoysiagrass as a golfing surface, playability, and maintenance requirements. We starte

Total organic material, soil organic matter, and screens

Thatch and mat at the top of turfgrass rootzones are removed from soils prior to testing for soil organic matter. Total organic material (OM246) testing is designed to me

GCSAA seminar overview, condition-based maintenance, and PAR

This gives an overview of the seminars I presented at the GCSAA Conference in 2026 and discusses updated PACE Turf site analyses of photosynthetically active radiation (P

Research words, a new Turf Twitter analysis, and tropical grasses with Maggie Reiter

Maggie Reiter joined me to discuss her "Finding Turf Twitter" analysis, her analysis of current turf research topics at the ASA-CSSA-SSSA meetings, tropical grasses, and

A blunt conclusion about coring

Scientific writing is not always as clear as this. There's an article I really enjoyed that stated right at the start, in the abstract, that core aeration "might not be w

Flights & turf photos with Dr. John Kaminski
