Nitrogen harvested in clippings: calculation update for 2024

I use a method based on clipping harvest and normal leaf nitrogen content to find the estimated nitrogen harvest. I adjust this based on species, because there are differences in the clipping volume to dry mass conversion based on what type of leaf we are working with. There are also differences between species in leaf N content, as you’ll see in the posts listed below.

My explanation of this method is something I wrote about in March as Nitrogen harvested in clippings: calculation update for 2024. I published that as a PACE Turf update.
