A micro-plot field experiment with reduced urea <sup>15</sup>N application was conducted to study the effects of urease inhibitor NBPT (N-(<i>n</i>-butyl) thiophosphoric triamide) and nitrification inhibitor DMPP(3,4-dimethyl-1H-pyrazolium dihydrogen) on the fate of applied urea <sup>15</sup>N; it aimed to find an efficient way to reduce the urea N application rate while improving the agronomic and environmental benefits. Five treatments were installed, i.e., 180 kg N/ha (N<sub>1</sub>, conventional application rate), 126 kg N/ha (N<sub>2</sub>, reduced to 70% conventional application rate), N<sub>2</sub> + NBPT, N<sub>2</sub> + DMPP, and N<sub>2</sub> + NBPT + DMPP. Compared with treatment N<sub>1</sub>, all the other treatments had a significantly higher total <sup>15</sup>N recovery by both soil and plant (<i>P</i> < 0.05 48.20, 41.39, 37.69, 38.85 and 34.83% soil recovery for N<sub>2</sub> + NBPT + DMPP, N<sub>2</sub> + DMPP, N<sub>2</sub> + NBPT, N<sub>2</sub> and N<sub>1</sub>treatment, respectively; and 42.68, 40.86, 40.25, 37.18 and 36.30% plant recovery for N<sub>2</sub> + NBPT + DMPP, N<sub>2</sub> + DMPP, N<sub>2</sub> + NBPT, N<sub>2</sub>, and N<sub>1</sub> treatment, respectively). In the plant <sup>15</sup>N recovery, the <sup>15</sup>N absorbed in grain/stem was highest in treatment N<sub>2</sub> + NBPT + DMPP. The maize biomass and the maize yield had a slight increase in treatment N<sub>2</sub> + NBPT + DMPP, compared with those in treatment N<sub>1</sub>. In sum, for the maize production in study area, N<sub>2</sub> + NBPT + DMPP application method would be a feasible way to ensure the normal maize yield while improving yield quality, saving urea fertilizer, and protecting the environment.

A field trial was conducted to assess the emission of ammonia from rough cattle slurry and solid and liquid fractions (generated from its mechanical separation) applied to alfalfa pasture. Three materials (rough slurry, liquid fraction and solid fraction) were applied on alfalfa over two seasons (summer and autumn), with two application rates (40 and 70 kg N/ha) and with two air velocities (0–0.6 m/s) at the soil surface. Ammonia losses were measured either by a set of wind tunnels (adjusting the air velocity at 0.6 m/s) or by a funnel system, allowing measurements to be recorded at an air speed close to 0 m/s. Each trial lasted 5 days with daily sampling of the gaseous emissions. Trial results showed that the rough slurry substrate had the highest level of ammonia emissions, followed by the liquid and solid fractions. Up to 35% of the applied total Kjeldahl nitrogen was lost as ammonia from the rough slurry in 5 days in summer conditions and with an air velocity of 0.6 m/s. No effect due to the application rate was observed, however, a significant effect of the temperature and air velocity on ammonia emissions was measured. Ammonia emissions after the spreading of the rough slurry were up to 26% higher when compared with those generated after application of the two fractions (solid + liquid).
