摘要:

Nitrogen losses through ammonia volatilization increased with increasing rates of application and were 6.8% of 112 kg urea-N/ha after 10 days. Initial humus moisture content within the limits studied affected volatilization rates in the first days but had little effect on overall losses. A discontinuous ammonia-trapping technique for field use is discussed.
