| Abstract/Contents: | "An old bromegrass sod established prior to 1929 and fertilized annually since 1954 with nitrogen at rates from 0 to 298 kg/ha responded with increased forage, protein, and seed yields. Nitrate-N content of the soil profile after 15 years of fertilization was analyzed using an Orion 401 specific ion meter with a NO3-N electrode to determine the possible pollution of ground water with nitrates attributable to increased nitrogen fertilization. Nitrate-N content was similar below 106.7 cm to a selected depth of 137 cm during late April and of 152 cm during late June and August in 1969 under each of six fertility treatments. Highest concentration of NO3-N was found in the soil profile from 15.2 to 61.0 cm in depth. Results suggest apparent lack of NO3-N movement and accumulation in fine-textured soils under northern climatic conditions even under high rates of continuous nitrogen fertilization." |
