Within the scope of the annual tractor tests on the motor test bench of the FAT, performance and consumption data as well as the waste gas components HC (unburned hydrocarbons), NOx (nitrogen oxides) and CO (carbon mo-noxide) are measured. The model developed on the basis of this data allows the calculation of the waste gas components as a function of fuel consumption, performance and engine speed. The values on consumption and waste gases serve to establish environmental life cycle assess-ments and energy balances.
Those wishing to promote biodiversity in agriculture by means of result-based schemes need meaningful indicators. An overview of proposed and used indicators highlights developments and challenges.
Foods of animal origin – friend or foe? It all depends on the needs of consumers and on local production conditions, as shown by a major review in which Agroscope took part.
In vegetable production it is usual to leave crop residues on the field. Measurements carried out by Agroscope researchers show that removing these residues significantly reduces nitrate leaching.
