bentgrass

When I see a photo like the P deficiency one shared by Ben Pease (see photo below), I am really curious to know the soil test levels of the element.

The idea that golf courses in Japan with the two green system have a summer green and a winter green is not quite correct. Nor is the two green system used exclusively with one warm-season grass green and one with cool-season grass.

Doug Soldat has photos showing more snow mold where potassium fertilizer was applied. Where potassium was not applied, there is less snow mold. Tried something new this year. Top left high K for six yrs, but no K after Aug 2016.

The recording of my webinar on preventing nutrient deficiencies is available in Spanish and in English. This was fun. I hope you’ll read the handout too. It is only 4 pages, with lots of white space, and gives a brief overview of this important topic.

I’m bombarded at this time of year with reminders, notices, descriptions, and articles telling me about the importance of frost delays. Apparently, frost delays are essential for the health of the turf.

Play on frosted bentgrass greens in Japan is not uncommon. Winston Mirmow’s thesis on Fall potassium fertilization and winter traffic effects on a creeping bentgrass putting green has some surprising results.

I was wondering what the effect was. I expected a 1 or 2 °C decrease in nighttime soil temperature in drier soils, compared to soils with more water. I didn’t find it.

I look forward to some photos from Doug Soldat. For many years, he’s had some fascinating photos to share of snow mold on creeping bentgrass. And each year, there was more snow mold where potassium fertilizer was applied, and less snow mold where potassium wasn’t applied.

This is something that has never made sense to me. Actually, it seems ridiculous. Zoysia greens are not renowned for being especially fast. But zoysia has especially high silica content in the leaves.

Adam Garr asked if there is a great resource on morning light for turf: Can anyone point me to a great resource explaining the importance of morning sun on greens that I can share with members?
