Dynamics of ammonia volatilization and nitrous oxide production from urine patches in grazed pastures
(Lincoln College, University of Canterbury, 1984)
A continuously aspirated enclosure method was used to measure ammonia (NH₃) volatilization from simulated sheep urine patches in a perennial ryegrass (Lolium perenne) / white clover (Trifolium repens) pasture in the field ...
Field studies of ammonia volatilisation potentials of unsaturated soils fertilised with granular urea
(Lincoln University, 1991)
The potential for ammonia, NH₃, loss from granular urea applied to soil can be influenced by various soil, environmental and agronomic factors. A series of field studies were conducted to investigate the soil factors ...
