| Abstract/Contents: | "This experiment was carried out to study the effect of pure nitrogen fertilization on botanical composition of grassland in 1987-1988 under practical conditions at the "Federal Institute for Agriculture in the Alps" in Austria. The application rates were 0, 30, 60, 90, and 120kg/ha/cut, the cutting regiumes 3-, 4-, 5-, and 6-cuts/year. The results were as follows: 1. Only PK-fertilization resulted in higher botanical composition of Trifolium repens among legumes in grassland, which was increased by cutting frequency. 2. Nitrogen fertilization on three-cut areas resulted in higher existence of generally valuable tall grasses such as Arrhenatherum elatius, Trisetum flavescens and Dactylis glomerata. On the other hand, nitrogen fertilization on four-, five- and six-cut areas showed mainly Dactylis glomerata and Poa pratensis appearance. 3. For some cases, appearance of less valuable grasses, herbs and weeds such as Agropyron repens, Poa trivialis, Poa annua, Setaria viridis, Aegopodium podagraria, Menlandrium rubrum, Taraxacum officinale, Achillea millefolium, Rorippa sylvestris and Polygonum aviculare was increased on medium and high rates of N-fertilized areas. 4. Reduction of sward density may also diminish the advantages of nitrogen fertilization and may be threatened by mainly high dressings of nitrogen combined with too late utilization of the sward. 5. Location altered the efficiency of nitrogen fertilization on botanical composition." |
