Chlorpropham (CIPC), the main sprout suppressant used when storing commercial potatoes, is now prohibited in Switzerland. Agroscope tested alternative substances in order to guarantee the production of indigenous chips and crisps.

100%-organic feeding of piglets has been discussed for a long time. A feeding trial on commercial farms shows that completely organic diets are suitable for piglets, and that their introduction is facilitated by a longer suckling period.

Korkaric M., Hanke I., Grossar D., Neuweiler R., Christ B., Wirth J., Hochstrasser M., Dubuis P.-H., Kuster T., Breitenmoser S., Egger B., Perren S., Schürch S., Aldrich A., Jeker L., Poiger T., Daniel O.

Agroscope examined whether it is possible to forgo the use of PPPs with a high risk potential for the environment. The results show that this would make effective crop protection more difficult, especially for field and vegetable crops, but also in organic farming.

Sown wildflower strips improve pest control, and diverse, perennial strips also improve pollination services. Hedgerows in Switzerland yielded good results, while internationally effects were inconsistent. The effects on yield were variable.

A strong immune system is important for health. Foods that are rich in propionic acid, such as Emmental cheese, have a supportive effect, and are a possible alternative to compounds with synthetically produced propionic acid.

Microbial activity in the soil is an indicator of soil health. An analysis of data series from the cantonal soil-monitoring networks over a ten-year period confirms textbook knowledge and shows what we need to look out for.

Researchers from Agroscope, Eawag and ETH have developed a method for the comprehensive detection of organic pollutant residues in soils and sediments. Initial results show that, in addition to known substances, there are also a number of substances detected for the first time.

White Clover is an important element of intensively used meadows and pastures. Of the 19 varieties tested by Agroscope, two new top varieties came out clear winners for nearly all traits.

Ever decreasing amounts of plant-protection products are being used in field crops; however, the quantity alone does not determine the risk for the environment, as discussed in a new Agroscope study on the use and risk of plant-protection products in Swiss field crops.

The genetic selection of hyperprolific sows has led to a rise in the number of piglets that are underweight at birth, often runtier and with stunted growth. A study tested the effect of a supplement on their development.

Schori F., Heublein C., Südekum K.-H., Gill F. and Dohme-Meier F.

Feed selection on the pasture costs cows time and energy. With the aim of optimised pasture feeding and efficient resource use, the feed selection of Swiss and New Zealand Holstein cows was compared.

Raw milk and raw-milk products can affect our health in both positive and negative ways. A study conducted by Agroscope summarises current findings from the research literature and classifies the positive effects and risks.

Around one-quarter of the utilised agricultural area in Switzerland is drained. Plant-protection products (PPPs) may enter watercourses via this route. Agroscope analysed the influencing factors and evaluated measures against PPP loss.

Good varieties of smooth-stalked meadowgrass are few in number. The positive results of the variety-testing programme give reason to hope that two new cultivars will soon be added to the range of top varieties.

Groher T., Heitkämper K., Umstätter C.

Digital technologies represent an opportunity for the modern management of farms. For this, already available technologies must also be utilised in practice. An Agroscope survey illustrates the status quo of technology use.

Plant production 04.06.20

Groher T., Heitkämper K. and Umstätter C.

Digital technologies are fixed features of modern agriculture – but to what extent are they already being used in Switzerland? A survey conducted by Agroscope provides answers to this question. Digital technologies reduce the physical workload of farming and contribute to sustainable field management. They also enable optimised management decisions based on plant- or soil-related…

Farms operate with a balanced nutrient cycle. Agroscope adjusted the reference values for suckling calves to the latest advances in animal production. The values for feed intake and nutrient excretion are now lower.

Protecting sheep from large predators means more work and higher costs for alpine farmers. The economic consequences of the necessary adjustments were investigated in 2017 and 2018 on 13 alpine farms in the cantons of Uri and Valais.

Grassland-based milk and meat production promotes the site-specific feeding of ruminants. With the AP22+, the reduction of protein supply via concentrates is under discussion. Agroscope studied the effects of limited protein supply.

Kaolin was tested in viticulture to control the dreaded pest Drosophila suzukii. The trials showed that this natural product has a comparable efficacy to conventional insecticides without any adverse effect on wine quality.

The risk of nitrate leaching is higher in field vegetable production than in arable crops or grassland. Different species of vegetables have different leaching potentials, which can be reduced through appropriate management.

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.

Since 2007, only free-farrowing pens may be used in Switzerland. Since then, litter size has increased significantly. Despite this, piglet mortality during the lactation period has remained stable over the years.

The number of farms with a minimum area of 30 ha is growing, and specialisation – particularly in animal production – is on the increase. Even so, structural change is proceeding at a slower pace in Switzerland than in neighbouring countries.

Ollagnier C. and Pradervand N.

Alternatives to antibiotics must be found to combat antibiotic resistance in animal production. The forage plant sainfoin reduces postweaning diarrhoea in piglets, thus reducing the need for antibiotic treatment.

Grazing dairy cows is a characteristic feature of Swiss agriculture. In order to use pasture efficiently, the estimation of herbage mass is recommended. Agroscope compared two methods and developed estimation formulas for implementation in practice.

The term ‘agrobiodiversity’ refers to the variety of plant cultivars and species that feature in the human diet. A study in four European countries shows that consumers are interested in this diversity. The genetic diversity of food-crop varieties and species is archived in state gene banks, and continues to serve as a starting point for…

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.

To protect Swiss cheeses from counterfeiting, Agroscope has developed marker cultures from lactic acid bacteria that allow the origins of the cheese to be determined. Proof-of-origin cultures for extra-hard cheeses are now also available.

Adapted, productive grass cultivars are crucial for Swiss forage production. Over the past 30 years, the most important grass species – perennial ryegrass – has been substantially improved by breeding.
