Title: Study on Ammonia Volatilization from Calcareous Soil

The results show that the different forms of N fertilizers had different volatilization amount at lower temperature. Ammonium bicarbonate was the largest volatilization followed by ammonium sulphate and urea. However, three forms of N fertilizers had almost same amount of N loss by volatilization at high temperature and larger than N loss by volatlization at lower temperature. The mixture of N fertilizer with soil could markedly decreased N loss by volatilization as compared with surface use.On the other hand, the mixture of using N fertilizer with superphosphate had a significant effect on protection ammonia volatilization from ammonium bicarbonate.Read More
