It's a busy Monday out here on the course and the greens are really getting a workout.  Today the greens were aerified with needle tines and then topdressed with sand.  On top of the sand topdressing, we also applied a potassium fertilizer to help with fall rooting and gypsum to maintain soil structure and to help remove harmful salts from our irrigation water that build up in our soil.  The sand, fertilizer, and gypsum were then dragged into the turf canopy and hopefully, some will work its way into the small aerfication holes.  Next the greens were rolled to smooth out the small bumps from the aerifying and now we are spraying the greens with a surfactant which reduces localized dry spots and helps water move deeper into the ground.  After all this work, the greens will get a deep watering this afternoon, so they may be a little on the soft side tomorrow.
