"Aside from allowing me to cut my nitrogen rates in half without compromising turf quality, I have seen reductions in turf diseases, thatch, required mowing, fuel use and labor"

"It might seem obvious but the rate at which your grass grows has a huge impact on how expensive it is to maintain"

Those are the results Jason Haines described in his post about the evolution of precision fertilizer application. He explains how he makes use of observations, measurements, and predictions to find site specific nutrient requirements. It’s a good read, and it has this animated chart that shows how N rates have... [Read More]

Year to date rain, and bermudagrass quality

Yesterday I wrote that bermudagrass fairways in Thailand wouldn’t be as good as they are in the Algarve because of climate differences. The cumulative rain so far this year makes a nice illustration of this. These data are through early November, and Trang in southern Thailand had received 2708 mm... [Read More]

The Palm Springs inflection date in 2017

Last week I wrote about some calculations to find the inflection point when the temperatures change from being better for warm-season grass (like bermudagrass, seashore paspalum, or zoysia) to being better for cool-season grasses (like perennial ryegrass, creeping bentgrass, or kentucky bluegrass). This inflection point can be represented on a... [Read More]
