“According to the Swiss Federal law on Agriculture (article 316), ecological subsidies”” are paid to farmers only if they respect special ecological rules on their farms. One of the major objectives of ecological measures is the conservation and increase of biodiversity in agricultural landscape. Five to seven percent of the land of each farm in Switzerland must be set aside for ecological compensation. By ordinance, the Swiss Federal Office of Agriculture (SFOA) is responsible for assessing the effects of ecological measures in agriculture on environmental indicators. One of these is biodiversity. The SFOA has entrusted the Swiss Federal Research Station for Agroecology and Agriculture (FAL) with two long term projects lasting both 10 years. The objective of the projects is to assess the effects of ecological measures (imposed to the Swiss farmers by law since 1993) on biodiversity in agricultural landscape. The paper describes the concepts of the two projects which started in 1996 and it presents the ongoing investigations.”
A comparison of different methods of winter-wheat fertilisation with nitrogen showed that nitrogen surpluses can be significantly reduced by means of site-specific variable-rate nitrogen fertilisation.

Many tile drainage systems on arable land are in need of renewal. Cantons and stakeholders will now be given a decision-making tool enabling them to assess such areas in detail and to find sustainable solutions.
Ammonia emissions from the Swiss farming sector have scarcely declined over the past 20 years. This is because the factors leading to either an increase or decrease in emissions have for the most part cancelled each other out between 2000 and 2020.
