Abstract
7-day-old sorghum seedlings were grown in balanced nutrient solution to which K (as KCl) was added at concentrations ranging from 12.7 to 767 mu M at a fixed pH of 5.6 plus or minus 0.2. As the K concentration increased, the absorption of this element by the plant rose hyperbolically, reaching 50 mu g/5 plants at 30 mu M and 100 mu g/5 plants at 800 mu M. The uptake of Mg fell linearly as K increased, from 15 mu g/5 plants at 30 mu M to 2.5 mu g/5 plants at 800 mu M. The uptake of P remained constant at 20 mu g/5 plants irrespective of the level of K in solution
