Ammonia Emissions and Emission Factors: A Summary of Investigations at Beef Cattle Feedyards on the Southern High Plains

Waste to Worth home | More proceedings…. Why Study Ammonia Emitted from Feedlots? Ammonia volatilization is a major component of the nitrogen balance of a feedyard, and the effects of ammonia loss range from the economic (loss of manure fertilizer value) to the environmental (air quality degradation, overfertilization of ecosystems). Although not yet regulated, ammonia …

Designing Structures to Remove Phosphorus from Drainage Waters

Waste to Worth home | More proceedings…. Abstract Several groups have developed P removal structures, which are units filled with P sorbing materials and designed to channel runoff water through them while retaining the filter material and P.  The goal is to prevent P from entering a surface water body and allow filtered P to …

Manure Application Method and Timing Effects on Emission of Ammonia and Nitrous Oxide

Waste to Worth home | More proceedings…. Abstract We conducted a field study on corn to evaluate the effect of liquid dairy manure applied pre-plant (injection or surface broadcast with immediate or 3-day disk incorporation) or sidedressed at 6-leaf stage (injected or surface-applied) on emission of NH3 and N2O. Manure was applied at a rate …
