Vol. 37, No. 5/6, March 2006, p. 811-826.# of Pages: 16 Publishing Information: New York, NY: Marcel Dekker Keywords: TIC Keywords: Nitrogen ; Potassium ; Fertilizers ; Comparisons ; Nutrient uptake ; Lolium perenne ; Fertilizer combinations ; Absorption Abstract/Contents: "It was hypothesized that supplying potassium (K) in concentrated complex fertilizer (CCF) form with nitrogen (N) (NK CCF) to all fertilizer microsites, rather than in NK-blended fertilizer form to a fraction of the total fertilizer microsites, should enhance the rate of K uptake by perennial ryegrass. Two complementary pot experiments were conducted to test this hypothesis. The results demonstrated that plants fertilized with an NK CCF absorbed K at faster rates than those fertilized with an NK blend and that use of K2 SO4 in place of KCl as the K source lowered the rate of K uptake by plants regardless of fertilizer form. Form of fertilizer (i.e., CCF or blend), however, had no effect on NH4 + or NO3 - uptake. Unfortunately, the positive effects of the CCF on K absorption were only manifest during the second 2 weeks of regrowth and did not result in significant improvements in dry matter production by the end of the 5-week regrowth periods."
