ABSTRACT
Soil properties, local climatic conditions and fertilization method in purple soil regions may significantly affect ammonia volatilization(AV). In this study, the effects of different fertilization methods on AV from purple soil were investigated during summer maize growth in middle Sichuan Province. Two different AV measurement methods(i.e., wind tunnel method and continuous airflow enclosure method) were compared to better quantify ammonia emissions from croplands. Five fertilization methods with three replicates were used in the experiment included CK(no nitrogen fertilizer), BC(broadcast urea, which is the local conventional practice), BC+Limus [broadcast urea amended with urease inhibitor Limus(a new urease inhibitor developed by BASF)], Band1(band urea once), Band2(band urea twice). The AV in all the treatments was determined by enclosure method. For BC treatments, AV was monitored by a wind tunnel system simultaneously. Results showed that AV loss rates were greater than 40% in BC, but only 4.8%, 3.8% and 1.3% in BC+Limus, Band1 and Band2, respectively, a reduction of 90%, 92%, and 97% as compared with BC. Ammonia loss rate(48.4%) measured by continuous airflow enclosure method was slightly higher than that by wind tunnel method(41.9%), but no significant difference between them was found.
