Nitrogen fertilization of potatoes
American Potato Journal, 19581. Yield increases under irrigated Long Island conditions were obtained with applications up to 210 pounds of nitrogen per acre with Cobbler and Katahdin varieties. 2. Nitrogen distribution had little effect on yield as long as vines were allowed to go to maturity. 3. When less than 70 pounds of the total nitrogen was applied

The Impact of Nitrogen Fertilization
1980A main source of anthropogenic nitrous oxide in the future will be the increasing use of industrially produced nitrogen fertilizers. Biological processes in the soil convert fixed nitrogen to N2O which is emitted to the atmosphere. Large uncertainties are connected with these production processes, and reliable estimates of their efficiencies are ...
