Using #OM246 Test Results To Get Net Organic Material Accumulation Rate The ATC Doublecut With Micah Woods podcast

32:10

Green speed varies because of many factors. One of those factors is clipping volume. I discuss that relationship and give some advice for those getting started with clipping volume and wanting to know how to adjust it.

Did you know there was a time when up to to 2 lbs N per 1000 square feet per growing month, the equivalent of 100 kg of actual N per ha per month, was a standard recommendation for putting green turf? I talk about this and some implications in this episode.

Constants in the turfgrass growth potential equation 23:43

14 weeks тому23:43

23:43

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 depending on whether you are making the calculation for cool-season grass, warm-season grass, and on whether you are using the Fahrenheit temperature scale or the Celsius temperature scale.

You can expect soil organic matter to be 5% nitrogen, and you can expect from 1 to 4% of that organic nitrogen to mineralize in one year. You can also calculate estimated daily mineralization and sum it to get weekly, monthly, and annual totals.
