Browntop greens, Poa annua suppression, pH, & OM testing with Grant Saunders

Grant Saunders is the course superintendent at Hamilton Golf Club in New Zealand. He has successfully overseen a green species conversion from Poa annua to browntop bentgrass (Agrostis capillaris). We discussed that, and the role of OM testing, and sand topdressing, and soil pH, and greenkeeping in New Zealand.

What is The ATC Doublecut with Micah Woods?

I discuss ATC blog posts, with supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.
