MORE than 300 landscapers crammed into a stuffy lower-level room at the Holiday Inn here recently, listening to the whys and wherefores of the new laws for keeping lawns green in Suffolk County while minimizing nitrogen pollution.
These studies show that the effects of catastrophic natural disturbance can be ephemeral, that impacts of human land use can greatly exceed those of natural disturbance, and that landscape features can play a very important role in minimizing nitrogen losses from humid tropical catchments.
The results suggested minimized ammoniacal nitrogen accumulation during hydrolysis (net removal up to 75%) with 3589 ± 469 mg/L soluble COD and 1419 ± 136 mg/L TVFA concentration at pH 7.2 to 7.5, temperature 43 48 °C, Aeration 0.19 0.22 vvm.
Development of crop varieties with high nitrogen use efficiency (NUE) is crucial for minimizing N loss, reducing environmental pollution and decreasing input cost.
Catalytic hydrogenation of nitrite in drinking water demands control over the selectivity towards nitrogen, minimizing the formation of ammonia.
These include formamide, glycerol, NP-40, Tween 20, trehalose, EcoSSB and 7-deaza-2'-deoxyguanosine 5' triphosphate (dc7GTP) [39] [43]]–[43]; dc7GTP works differently than the other additives in that hydrogen bonding between neighboring guanines is minimized due to nitrogen displacement from position 7 of the base ring to position 8.
To minimize leaching of nitrogen between sub-plots, the plots were arranged in a split-plot design, with nitrogen treatments applied to blocks comprising eight plots.
(1) should possess equal to or better complex forming properties compared to commercial chelating agents, (2) should possess better biodegradability, and (3) should contain low nitrogen to minimize the nitrogen content in effluents.
Adequate predictions of rumen-degradable protein (RDP) and rumen-undegradable protein (RUP) supplies are necessary to optimize performance while minimizing losses of excess nitrogen (N).
Experiments were performed in a nearly isothermal flow reactor using mixtures diluted in either argon, helium, or nitrogen to minimize the temperature changes from chemical reactions.
