A potassium reserve in the soil: non-exchangeable and mineral K
I talk about two research projects in which one would have every expectation that the grass would respond to K fertilizer, but did not. What happened? The grass was able to get all the K it needed from the release of mineral and non-exchangeable K in the sands. This has obvious implications for soil test interpretation and K fertilizer recommendations.
I talked about this blog post: https://www.asianturfgrass.com/post/potassium-reserve-in-the-soil/
