Abstract/Contents:"This study evaluated post sprigging nitrogen requirements during the 8 to 10 week establishment period and quantified nitrate loss. Two studies were conducted. The first study consisted of 1.8m x 1.8m plots, with nitrogen rates ranging from 4.9 kg N/ha/wk to 48.8 kg N/ha/wk. A second study quantified nitrate loss via leaching. All plots were rated weekly for cover, color and density. In 1998, typical weekly nitrogen rates were in excess. Similar results for 8 and 10 week cover, color, and density, and 11 week biomass were found using 48.8 kg N/ha to 97.6 kg N/ha during the first 4 week period. Only 195.2 kg N/ha to 244 kg N/ha was necessary during the total grow-in, a 35% reduction. Lysimeter results revealed large quantities of nitrate loss and specific values for many sampling dates exceeded EPA drinking water standards. Reducing nitrogen rates during the first 4 week period will minimize nitrate loss, without compromising establishment."
