For the past two years on April 22 I looked at which devices are used to visit this site. Now I have looked up the data for the past year. Mobile continues to increase as a proportion of visits. Tablet and desktop visits continue to decline.

With just a few clicks, you can get a link to download a representation of the turfgrass growth potential at any location. My favorite part of the app? The file names. We wrote the app to make sure… Continue reading A list of turfgrass Shiny apps
Turfgrass growth is affected by temperature. The temperature-based turfgrass growth potential (GP) is an easy way to look at how the actual temperature is related to the optimum temperatures for growth. PACE Turf put together this GP avatar Shiny app to generate a simple plot of cool-season and warm-season grass GP. There are two options… Continue reading The GP Avatar app

These Shiny applications make calculations related to turfgrass management. Evapotranspiration (ET) calculator Returns the reference and crop evapotranspiration for a day given inputs of latitude, maximum and minimum air temperatures, and crop coefficient. Based on the Hargreaves equation. Sustainability index Returns the sustainability index (SI) based on soil test inputs. This is a direct comparison… Continue reading Six turfgrass Shiny apps
Last year I looked at which devices are used to visit this site. Now I have looked up the data for the past year. As expected, phones have now become the most common device used by visitors to this site.
