The «Nitrogen-Project» has been mandated by the Swiss Federal Office of Agriculture and was elaborated at the Institute for Agricultural Economics at ETH Zurich. In the framework of this research project a recursive-dynamic agricultural allocation model has been used to anticipate the development of nitrogen emissions from agriculture on the sectoral level. This article provides an overwiew of the optimisation model and summarises the most important nitrogen-related results that have been estimated with model-based calculations for two agro-political scenarios. The model results show that the policy targets of the agricultural package AP 2007 for the year 2005 have only been reached with respect to agricultural ammonia emissions with an intended reduction of 9 %. Furthermore, our results show that from 2005 to 2013, environmentally harmful nitrogen emissions will not substantially decline just by continuing the present agricultural reform process (agricultural packages AP 2007 and AP 2011).

Agroscope researchers tested the FAO method for assessing the agroecological status of farms in Switzerland for the first time, demonstrating the advantages of a holistic evaluation as well as the limits of the tool.
In wheat crops, pesticides can be used more sparingly without sacrificing cost-efficiency. With oilseed rape the situation is more difficult, since the reduced yields are not offset by higher revenues. These are the findings of the analysis of the first two harvest years of the PestiRed project.
Soil samples can be measured directly in the field by means of spectroscopy. Agroscope researchers have tested mobile devices and shown how to make the best use of them.
