| Abstract: | Increasing concentrations of K (20, 200, 2000 μm) in the nutrient solution depressed Ca content and concentration in barley plants growing in nutrient solutions of low Ca concentrations (250 and 2500 μm). Increasing K from 20 to 200 μm depressed Ca absorption more than increasing K from 200 to 2000 μm K. |
