Core sweepers make aeration easier, ball roll after 270 rounds, and estimating N in clippings

I discuss small plot university research with fixed treatments vs. golf course and sports turf maintenance with treatments that vary, and consider which results we should trust more. I also discuss the bobble test after 270 rounds, mention that core sweepers are a nice machine, and explain how I estimate N harvested in creeping bentgrass clippings.
