Agroscope compiles annually updated inventories and projections for Swiss agricultural greenhouse gas emissions. With the change to reporting under the Paris Agreement, new bases for calculation must be taken into account. Despite this, the overall picture for agriculture remains largely unchanged.
The dairy sector is urged to reduce negative environmental impacts. But dairy is not only milk: depending on the production system and cow breed, relevant amounts of meat as by-product result. How can emissions thus be allocated to milk and meat?
With the help of satellite data, yields can be estimated both over a wide area and at individual field level. This is also possible in small-scale Swiss agriculture, as shown by a team consisting of ETH Zürich, the University of Zurich and Agroscope.
Suitable both as food for humans and as livestock feed, sorghum thrives even in an increasingly dry climate. Agroscope has developed maps showing the potential growing areas for silage- and grain sorghum.
The available forage, climatic conditions and the measures for reducing ammonia emissions can adversely affect protein supplies for suckler cows. What is the impact on the weight and intake of the cows and their calves?
The energy expenditure for staggered greenhouse tomato production would be twice as high as that of the current means of production with no appreciable increase in yield. Even so, the current means of production might benefit from LED lighting.
Persistent organic pollutants may accumulate in the tissues of suckler cows and their calves. Agroscope and Empa studied the processes by which these undesirable substances accumulate as well as the decontamination of previously exposed animals.
Previously, grain diseases transmitted by seed were controlled with synthetic-chemical seed dressings. However, if seed is healthy, no treatment is necessary. As the demand for pesticide-free grain increases, professional seed inspection is gaining importance.
Pest prevention plays an important role in reducing pesticide use. Nevertheless, the use of such measures is below the social optimum. A generally cautious attitude towards risk and adoption of other risk management measures hinder farmers' prevention efforts.
A review on the current scientific literature showed that pesticides are widely present in soils, water and air and have a potential to contaminate organic produce. These contamination pathways must be considered when findings of pesticide residues are investigated.
The number of plant-based beverages on supermarket shelves is constantly increasing. The physicochemical properties of these beverages, such as their colour or foamability, vary according to the plant they are made from, and determine their use as an alternative to milk.
Agroscope has developed risk indicators which show the development of risks associated with the use of plant protection products for important environmental compartments, describe the risk potential of the active substances and take account of legal measures for risk mitigation.
Selected microorganisms extend the shelf-life of foods, thereby contributing to a reduction in food waste. In a study of the literature, Agroscope highlighted the important role of protective cultures and fermentation.
Do farmers who produce in environmentally friendly ways earn less income? As an Agroscope study shows, this needs not be the case, and farmers can actually generate more revenue by protecting the environment.
In temporary grassland, alfalfa is used mainly in three-year mixtures for dry locations. Following recent variety trials, Agroscope has added the new varieties Nutrix and Andantino to the list of recommended forage plants for 2023–2024.
It’s not easy to change eating habits. In a study of the literature, Agroscope investigated which policy measures favour a sustainable diet. Market-oriented tools and bans prove effective, but are fairly unpopular.
Oats, triticale, hull-less barley, lupin, faba beans and buckwheat are rarely cultivated. The EU project CROPDIVA intends to change that. Agroscope analyses the value chains of four of these crops in order to promote their cultivation and processing.
A hoeing and spot-spraying device enables huge savings in the use of plant protection products. Although costs are higher than for conventional plant protection devices, motivated farm managers give this innovative technology genuine prospects for the future.
Thanks to their unique landscapes, the 15 regional nature parks, the majority of which are located in the (pre-)Alps and in the Jura Arc, feature as tourist attractions. But do the parks also provide economic value-added for local agriculture?
To balance their nutrient cycles, Swiss farms export surplus farmyard manure to farms with free uptake capacities or to composting and anaerobic digestion facilities. Between 2015 and 2020 the volumes of organic manure and recycled fertilisers transported rose significantly, with a consequent increase in transport costs.
Which measures are suitable for significantly reducing pesticide use in field crops? In the PestiRed project, farmers rate the implemented measures as largely positive; with a differentiated result for economic efficiency.
