How to find the photosynthetically active radiation (PAR) anywhere 37:29

рік тому37:29

I explain that moving from full sun to tree shade reduced photosynthetically active radiation by about 80%. I show an app, and a PACE Turf document, that will allow you to find both PPFD and DLI no matter where you are located.

Achieving the lowest possible #OM246 total organic material value is not desirable, because the living plant material is part of the OM measured with this method.

Calculation of the average daily temperature 18:26

A common way to calculate average daily temperature is to take the sum of the daily maximum and daily minimum temperatures, and to divide by two. A better statistical approximation of the average temperature is to take measurements made every hour and then to find the mean value of those continuous measurements. This blog post shows a comparison of…

The PACE Turf growth potential equation has one variable (the actual air temperature) and two constants. The constants are optimum air temperature and a term for variance that controls the shape of the curve as the actual temperature moves away from the optimum temperature. It's a little more complicated than that, because the constants change depe…
