Chapter 17 Predicting organic matter in turfgrass soils
Jason Haines has been sharing turf management ideas on his Turf Hacker (https://www.turfhacker.com/) blog, and one that I think is especially interesting is the idea that one can precisely match the topdressing sand quantity (https://www.turfhacker.com/2018/06/sand-o-meter.html) to the growth of the grass.30
I think this equation, or one similar to it, might predict what the soil organic matter content in turfgrass soils will be.
If that equation can predict soil organic matter, then it is relatively straightforward to adjust the variables on the right side of the equation in order to achieve the desired result on the left side.
And now for a different model! I’ve recently become aware of the Greens Organic Matter Management Tool by Ed McCoy. You can read about this model and get an excel file to work with at this link:
It is described as “a location-based model of organic matter fate within the sand-based surface layer of a putting green.”
This chapter is based on a post I made about this topic on the ATC blog at https://www.asianturfgrass.com/2018-06-29-predicting-organic-matter/.↩
