In a field experiment, a sandy loam was subjected to single passes with a sugar beet harvester at two different soil water potentials and two different hopper fillings. The moist plot responded to a wheel load of 11,23 t with an increase in bulk density and pre-consolidation pressure as well as with a decrease in air permeability and macroporosity at a depth of 0,12-0,17 m. With a wheel load of 7,47 t on the moist plot and with both wheel load levels on the dry plot, only slight changes of the soil structure were detected. At a depth of 0,32-0,37 m and 0,52-0,57 m, the measurements did not indicate any compaction. An ANOVA indicates that the factor “soil water potential” had the stronger influence than the factor “wheel load”.

The training programme for farmworkers imparts broad skills to academically weak learners. What chances do they have on the labour market today and in the future and how do they succeed in making the transition to further training?

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.
