[QUOTE="franklin, post: 4946552, member: 1118"] Yes. I would agree with this. Despite all manner of soil tests saying plenty of K, we always find that the plant simply cant take up enough when they start to shift. Even then, I cant get an economic return with foliar K, but seems silly to do all the science and then not apply any. Could it be that high levels of K actually lock up K? Similarly we are up to 800ppm mag but still see deficiency in the crops. Soil would suggest we have no sulphur, but never see it lacking in the crop. [/QUOTE]
