Title Effect of ventilation on ammonia levels in cowhouses
Bibliographic information Nov.1993, Vol.54, No.11, p.678-682. Illus. 12 ref.
Abstract Report on survey of ammonia concentration in Finnish cowhouses (cowsheds). Diffusion tubes were used to measure ammonia levels and were found to be reliable and sensitive for field purposes. The correlation between ventilation rates and ammonia concentration was generally poor, indicating that other factors are also important. Nevertheless, it is recommended to improve ventilation rates in order to reduce air impurities and relative humidity. Supply air should also be warmed in winter.
