“Sorry if this is a rubbish question”

This question came some months ago: “I’m just pondering something about MLSN levels for Bent vs Poa and so hopefully you can clear it up. Having seen a bit of research coming out about k levels affecting disease pressure differently for poa and Bent does that not mean there should be two different MLSN’s for… Continue reading “Sorry if this is a rubbish question”

“I don’t really need to show any data for this to be certain”

After Paul Robertson asked if anyone is using a Pelzmeter, a long discussion followed, and the notifications on my Twitter account blew up. I think the conversation is still happening. My only contribution to that conversation was to share a link to an article by Richards et al. that shows the Pelzmeter and the Stimpmeter… Continue reading “I don’t really need to show any data for this to be certain”

No matter how much sodium one puts into a sand rootzone, the soil structure cannot be affected, so gypsum won’t be required

I received this question about leaching salts from the rootzone: “I remember talking to you once before regarding flushing excess salts from the root zone and the application of gypsum or other calcium products before the flush and you telling me it was not necessary. I have since discovered that same conclusion for myself. I… Continue reading No matter how much sodium one puts into a sand rootzone, the soil structure cannot be affected, so gypsum won’t be required

17 essential nutrients?

I can explain the 17 and you’ll be an expert.” Here’s… Continue reading 17 essential nutrients?

“Already proving to be more valuable than I originally expected”

When I read Jason Haines’ interesting post about clipping yield, soil mineralization, and disease rates and came to the part where he said measuring all the greens was more valuable than he expected, I was glad to read that. I wanted to say “I told you so,” because this is a number that I think… Continue reading “Already proving to be more valuable than I originally expected”

Tonight’s reading

I saw a video today with the question “what is your favorite fertility practice?” That segment starts at the 2:00 mark. Then on Twitter I saw some comments about how funny the answers to that question were. I had a laugh because the answers are correct, but it is the question that misuses the word.… Continue reading Tonight’s reading

“Don’t try to jump on his bandwagon”

Jon Scott wrote to me about my recent post on a poor way to fertilise. “While this superintendent has solved his problem of nitrogen input by monitoring salinity level that has worked for him, this is probably a very unique situation. It may be relevant to other golf courses where similar salt levels exist, but… Continue reading “Don’t try to jump on his bandwagon”
