Abstract

A model for the transfer of ammonia from arable land to the atmosphere after surface application or incorporation of cattle slurry is presented. The model can be used to study the interactions of the chemical, physical and environmental factors influencing volatilization losses and their combined influence on NH3 volatilization under field conditions. The model employs the following flux equation: R = k (Cs-Ca) where k is a transfer function, Cs is the NH3(g) surface concentration and Ca is the atmospheric NH3(g) background concentration. The rate of volatilization R can be calculated at any moment after application, provided k, Cs and Ca are known at that moment. The model therefore basically consists of modules which yield these variables. (Abstract retrieved from CAB Abstracts by CABI’s permission)
