For more than forty years the Swiss Federal Research Station in Wädenswil (FAW) has operated a warning service for pests and diseases in perennial fruit crops in order to support the endeavours of growers towards a more ecological production. Designed as a decision support system, it is based on a close collaboration between FAW, the Swiss Meteorological Institute (SMA), the Research Institute of Organic Agriculture, the Cantonal Extension Services and the growers. It employs data from five automatic weather stations and a network of twenty warning computers to drive simulation models and to predict local pest phenology and disease epidemiology. In addition pests and diseases are monitored at roughly 100 different sites by means of twig sampling, visual counts and various types of traps. Information is compiled weekly at the FAW and recommendations distributed by mail, fax and more recently on the world-wide-web. In future new forecasting and communication tools will be implemented with the objective of improving accuracy as well as the spatial and temporal resolution.
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.
