Potassium levels scrutinized in ag crops also

The levels of soil potassium required for optimal turf growth are probably much lower than previously thought, as outlined by Dr. Micah Woods, in his recent podcast. But the scrutiny of the role of potassium in plant health is not restricted to turf, as a recent scientific article,"The potassium paradox: Implications for soil fertility, crop production and human health" makes very clear. In this article, University of Illinois scientists S.A. Khan, R.L. Mulvaney and T.R. Ellsworth conducted their own field…
