Title: Concentrations of N, P, K, Ca, Mg and Na in perennial ryegrass and white clover leaves of different ages Source: Grass and Forage Science . Vol. 49, No. 4, December 1994, p. 422-428.# of Pages: 7 Publishing Information: Oxford, Blackwell Scientific Publications Keywords: TIC Keywords: Nitrogen ; Phosphorus ; Potassium ; Calcium ; Magnesium ; Sodium ; Lolium perenne ; Leaves ; Trifolium repens ; Application rates ; Uptake Abstract/Contents: "Leaf blades of perennial ryegrass (Lolium perenne ) at five developmental stages, from unemerged to dead, were collected from cut swards grown under field conditions. Similarly, leaflets of white clover (Trifolium repens ) at four developmental stages, from tightly folded to proximal to the youngest fully developed leaf, were collected. The leaves were analysed for N, P, K, Ca, Mg, and Na. In perennial ryegrass, the concentration of N declined by about half and those of P and K declined by about two-thirds, as leaves aged. By contrast, the concentration of Ca increased more than fivefold and that of Mg about twofold as leaves aged. The concentration of Na initially increased more than twofold but then declined as leaves died. In white clover the concentration of N declined by about 20% as leaves aged, while the concentrations of P and K declined by about 50%; the concentrations of Ca increased about fivefold, that of Mg declined by about 15% and that of Na increased by about 15%. The application of N increased the concentrations of N and K in ryegrass leaf blades at all stages of development. The application of P increased the concentration of P and Na in the leaves of species."
