| Abstract/Contents: | In 3 pot trials, perennial ryegrass was grown in 21 soils without added K and K taken up by the ryegrass and released non-exchangeable K were determined. Correlation coeff. between K uptake and several soil K indices, and between non-exchangeable K released by ryegrass and soil K indices were calculated. K taken up in 1 trial ranged from 6.8 to 42.7 mg/100 g soil. |
