Abstract/Contents:"Nitrogen-form effect on nutrient uptake and the subsequent concentration of nutrients in turfgrass plant tissue has not been thoroughly investigated. This study evaluated the effects of clipping regime and N-form on the tissue concentration of macronutrients and micronutrients and macronutrient uptake in `Penncross' creeping bentgrass (Agrostis palustris Huds.). Turfgrass plugs were grown under greenhouse conditions in a modified Hoagland's solution with a combination of three nutrient solutions (100% NO3-, 100% NH4+, and 50:50 ratio of NH4+:NO3-) and two cutting regimes (cut and uncut). Concentrations of macronutrients and micronutrients were determined for shoot, root and verdure. Nutrient uptake was determined weekly. Uncut NO3--treated plants accumulated higher concentrations of K, Ca, Mg, B and Cu in the shoot tissue; P, K, Ca, Mg, B, Cu, Mn and Zn in the root tissue; and P, Ca, Mg, B, Fe and Mn in the verdure compared to uncut NH4+-treated plants. Nitrate uptake was greater with uncut treated NO3--treated plants than was NH4+ absorption with uncut NH4+-treated plants. Plants grown with the uncut 50:50 treatment absorbed more NH4+ than NO3-. Plants grown with the uncut NO3- and 50:50 treatments absorbed higher amounts of P, K, and Ca compared to the NH4+ treatment. The cut NO3--treated plants accumulated higher concentrations of K in the shoot tissue; P, Ca, Mg, B, Cu, Fe and Mn in the root tissue; and B in the verdure than did the cut NH4+-treated plants. Cut NO3--treated plants absorbed less NO3- than did cut NH4+-treated plants absorbed NH4+. The cut 50:50 treatment absorbed more NH4+ than NO3-. Plants grown with NO3- and 50:50 treatments, under both cutting regimes, resulted in higher concentrations of most macro- and micronutrients and greater nutrient uptake compared to the NH4+-treated plants."
