Abstract/Contents:"Relationships between soil nutrients, applied fertilizer, and turfgrass response are important in planning turfgrass fertilizer programs. A 4-year study was conducted to determine the effects of five N sources (urea, Agrinite, Milorganite, Uramite, and Nitroform), two K sources (KCl and fritted potash), and three K rates (0, 1.2, and 2.4 kg/100 m2) on soil nutrient levels and the growth and elemental composition of Penncross creeping bentgrass (Agrostis palustris Huds.). Soil test levels, elemental content of clippings, and clipping weights were used to evaluate treatments. Soil P and Mg levels were significantly higher with Milorganite as the N source. KCl applications increased K levels and decreased Mg and Ca slightly, whereas fritted potash increased both K and Ca. Tissue analyses indicated highest N with urea as the N source, lowest N with Agrinite, and highest P with Milorganite. Added K increased K in the clippings and decreased N, Ca, Mg, Mn, and Na. Although K additions decreased some elements in the soil and clippings, the magnitude of these changes was not considered critical under the conditions of these experiments. Significant yield differences due to N source decreased over the years. In general, clipping weights were not influenced consistently by K source or K rate; however, significant increases due to K have increased with time."
