Soil test interpretation and more: 4 seminars in Australia

I was in Sydney, Adelaide, and Brisbane this week to discuss the MLSN approach to soil test interpretation in four seminars organized by Living Turf. In these seminars, I explained that the use of the MLSN guidelines is as simple as planning how many beers to buy for an upcoming party. And at this party,… Continue reading Soil test interpretation and more: 4 seminars in Australia

Applying the grammar of greenkeeping

Over the past two weeks, I’ve had multiple conversations about the way I think of turfgrass management. It all starts with a definition of greenkeeping as managing the growth rate of the grass. I wrote about this in A Short Grammar of Greenkeeping. You can get your copy here. Application of the grammar allows for… Continue reading Applying the grammar of greenkeeping

Turfgrass and shade: daily light integral (DLI) in Sydney

The Australian Government Bureau of Meteorology (BOM) provide satellite-derived global solar radiation data. I downloaded 2015 and 2016 data for station number 66120 (Gordon Golf Club). The data are in energy units of megajoules per square meter per day. I multiplied by 2.04 to convert to daily light integral (DLI) units of moles per square… Continue reading Turfgrass and shade: daily light integral (DLI) in Sydney

GP and GDD: are they comparable?

Someone asked me at the Northern Green Expo if the temperature-based growth potential (GP) and temperature-based growing degree days (GDD) are comparable. They sort of are, with a couple of exceptions. Comparable, yeah, kind of. But they are not interchangeable. I downloaded the weather data for every day in 2015 from the international airports at… Continue reading GP and GDD: are they comparable?

Is it getting more difficult to grow bentgrass in Sydney?

Yes. Since 1859, the temperatures have increased, the temperature in the hottest month of the year (January) has increased, and the number of days each year with a low temperature above 21°C (70°F) has increased. Although the temperature at Sydney during much of the year is fine for creeping bentgrass, the amount of heat stress… Continue reading Is it getting more difficult to grow bentgrass in Sydney?

Turfgrass Growth Potential: 4 cities, 472 days

The temperature-based turfgrass growth potential predicts how grass growth can respond to temperature. This growth potential (GP) was developed by PACE Turf and has been put to many uses such as predicting the time of overseeding, estimating turfgrass nitrogen requirements, assessing turfgrass stress, and evaluating growth and optimum times for various maintenance practices. When the… Continue reading Turfgrass Growth Potential: 4 cities, 472 days

Webcast from the Australian Turfgrass Conference: Micah Woods on grass selection in Asia

The Australian Golf Course Superintendents' Association provide a great service by making so many of the presentations from their annual conference available for online viewing.  At the 27th Australian Turfgrass Conference in Adelaide, I gave presentations about turfgrass nutrient requirements, about grass selection, and about managing turf in microclimates. In this presentation about grass selection, I spoke primarily about manilagrass… Continue reading Webcast from the Australian Turfgrass Conference: Micah Woods on grass selection in Asia
