New Guidelines for Fertiliser Application

The 'Principles of Agricultural Crop Fertilisation in Switzerland' (PRIF) are primarily a tool for agricultural advisers, but also serve to help farmers with practical questions concerning the fertilisation of agricultural crops. In addition, the PRIF guidelines are used by researchers, political decision-makers and for legal enforcement. Agroscope is currently preparing a new edition of the guidelines for 2017. For the first time, fertilisation data for field crops, forage crops and special crops are presented in a complete work in modular form.

The new edition of the PRIF is coming soon in 2017

Stable Microbial Diversity in the Soil

There is enormous species diversity in the soil, and different land-use types and sites harbour different microbial communities. This is shown by the recording of the state of agricultural soils in the reference measurement network of the Swiss Soil Monitoring Network (NABO) by means of biological parameters (NABObio). Over four years, the microbial communities of the thirty NABObio sites on field and grassland and in the forest proved to be relatively stable.

New Sampling of Accounting Data

Since 2016, Agroscope’s agricultural income has been determined on the basis of a random sampling. From a certain size onwards, any farm can now be asked to make its accounts available, on a voluntary basis and in an anonymised form, to the Farm Accountancy Data Network. This approach leads to a significant improvement in the representativeness of the sample, compared to the previous, non-random selection of the farms.

High Rainfall Yields Good Resistance Data

Agroscope is currently studying eight cisgenic potato lines with resistance genes against potato late blight in a field trial on the Protected Site. Frequent, heavy rainfalls in 2016 favoured the development of this plant disease, which facilitated data collection. The result was clear: two of the resistance genes used proved to be completely effective against late blight, whilst two other resistance genes afforded partial protection to the plants.

Recommended Varieties of Forage Plants

‘The principle that only the best varieties are good enough is especially true for ley farming’ explains Daniel Suter of the Forage Production and Grassland Systems Research Group. Leafy, high-yielding persistent plants are desirable for forage production. The List of Recommended Varieties of Forage Plants contains all of the varieties that comparative variety trials conducted in Switzerland have proven to be the best. The List is also the basis for clover/grass mixtures with an AGFF (Swiss Grassland Society) quality mark.
