turf hacks

Last year I wrote about a soil temperature turfhack. The soil temperature is almost always between the day’s high and low temperature. The soil temperature at a 5 cm depth immediately after planting manilagrass stolons on 22 April.

It’s always a good idea to know what the soil temperature is. One can measure it, or one can be confident that the average daily soil temperature close to the surface (5 cm, or 2 inch depth) is higher than the daily low temperature, and lower than the daily high temperature.

I’ve written about the attractions of metric units and how facility with those units can make turfgrass management easier. I want to explain this a bit more, especially as it is related to fertilizer and to water, first discussing 2 dimensional surfaces.

Growing up and first working in the turfgrass industry in the United States, I naturally used US customary units: inches and feet, pounds and ounces, fluid ounces and gallons and so on.
