SKW Stickstoffwerke Piesteritz GmbH (SKWP), Germany, are a producer breaking new grounds of N fertiliser use by developing new innovative products including recommendations on best usage and practices with an emphasis on improving N use efficiency. We have an own research department with scientists in the area of chemistry, analytics and agriculture as well as an agricultural experimental station. During the last years we have generated fundamental results concerning NH3 and N2O emissions after application of N fertilisers under practical related conditions in typical German agricultural areas. We are the sole institution holding NH3 emission results over a three year typical crop rotation in Germany. In this study we identified and quantified options to reduce gaseous N losses significantly. In addition, we have experiences in efficient and loss reduced use of organic fertilisers like slurry or biogas digestate. We are open to integrate concertedly developed methods and measure in our existing research program and demonstrate best available practice in N fertiliser use.
