Excessively high work intensities did not lead to better results, not even with regard to soil loosening. In terms of the stability of the loosened soil structure, however, there are differences between the various implements. The increase of nitrate concentration due to tillage can be reduced significantly by planting appropriate green covers. Against the expectations, the least intensive tillage did not lead to the highest mineralisation. For this reason, the differences between the systems have to be considered as being insignificant. From a microbiological point of view, the least intensive tillage methods are sufficient. As opposed to repeated soil tillage, only ploughing led to a significant decrease of the earthworm population.

The Swiss agricultural sector currently makes little use of the opportunities offered by digitalisation. A charter launched in 2018 aims to further develop the digitalisation of the Swiss agricultural and food sector and to exploit the potential in the interests of all stakeholders.

Sowing oilseed rape with other plants reduces damage caused by adult flea beetle, according to a study conducted at Agroscope. This intercropping approach could limit reliance on insecticides and the emergence of resistant pests.
