On the Vertical Flux of Gaseous Ammonia above Water and Soil Surfaces
The vertical flux of ammonia gas has been determined above soil and water surfaces, in summer half-year, in Hungary. Above water surface the sign and the measure of the flux depends on the difference between the atmospheric ammonia level and the calculated equilibrium concentration. These concentration differences give a good correlation with the values of the measured flux. Above uncultivated soil surface deposition process takes place in most cases. It suggests that the atmospheric ammonia level generally exceeds the equilibrium concentration, determined by the chemical composition of soil. The average deposition velocity is 0.48 cm.s−1.
