Ammonia Volatilization from Flooded Rice Soils

  title={Ammonia Volatilization from Flooded Rice Soils},
  author={Duane S. Mikkelsen and S. K. DeDatta},
The recent publication by Mikkelsen et al. (1978) leaves the reader with some serious questions. The most important point to be raised concerns the methodology. Ammonia losses were estimated by two methods: (i) by scrubbing air before and after passing it through a jar placed over a soil, or, (ii) by collecting NHa in a static acid trap placed under a plastic canopy suspended over the water surface. The authors rightfully list wind velocity as one factor influencing ammonia volatilization, yet… CONTINUE READING
