Application Rate And Timing Effects On Urease Inhibitor Performance For Minimizing Ammonia Emissions From Beef Cattle Feedyards, David B. Parker, Syam Pandrangi, L. Wayne Greene, Lal K. Almas, N. Andy Cole, Marty B. Rhoades, Jacek A. Koziel

A laboratory study was conducted to evaluate how rate and timing of urease inhibitor application affects ammonia emissions from simulated beef cattle feedyard surfaces. The urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) was applied at rates of 0, 1 and 2 kg/ha, at 8, 16, and 32 day frequencies, and with or without simulated rainfall. Synthetic urine was added every 2 days to the manure surface. Gaseous NH3 was trapped in a sulfuric acid solution using a vacuum system and analyzed for nitrogen using automated procedures. NBPT applied every 8 days was most effective, with the 1 and 2 kg/ha NBPT treatments …

The objective of this fact sheet is to help producers understand the characteristics of different types of manure storage facilities. Factors that might influence the selection of a particular type of manure storage facility are discussed. Manure storage facilities discussed include solid systems, slurry systems, and liquid (lagoon systems).

Nutrient Concentrations In Manure Storage Facilities, John Harrison, Dallen Smith
All Current Publications
The objective of this fact sheet is to help producers understand the nutrient loss and retention characteristics of different types of manure storage. The concentration of nutrients in manure storage facilities is important for planning land application activities. Nutrient concentration is usually the critical factor in determining the amount of manure to be spread per acre of land. Manure systems similar in type and management may have characteristically similar concentrations of manure nutrients.

A well-designed manure storage facility must also be well managed to prevent environmental concerns from developing. Probably the single most important requirement in operating and maintaining a manure storage facility is to ensure that the facility does not overflow or discharge.
