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

The ATC Doublecut with Micah Woods

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.
