“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.

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.

Sand, leading to more growth, needing more sand, leading to more growth, needing more sand

Frank Rossi and Dan Dinelli had an interesting conversation on Turfnet Radio. I learned a few things, and I even agree with some of what they discussed. But not all of it. The first thing that came to mind when I heard them talking about sand and growth was lawns beside the ocean.

Original blog post here. @asianturfgrass maybe those that soil test are just more likely to fertilize in general? — Ryan Goss (@NMSUTurfgrass) December 29, 2016 There are two basic scenarios.
