Arbuscular mycorrhizal fungi (AM fungi) are soil fungi that establish an effective symbiosis with most crops and wild plants, promoting plant growth and improving soil structure. Individual studies from Switzerland have led us to assume that certain species are suitable as bioindicators for various soils and land-use types. In a broad-based study, the AM fungi…
There has been a drastic decline in farmland biodiversity in recent decades. In spite of direct payments for ecological compensation areas (ECA), specifically for their connectivity and ecological quality, there has been no general recovery in the populations of many species of farmland flora and fauna. While discernibly positive effects of agricultural biodiversity measures have…
Whey is present in large quantities in the alpine-cheese production zones, and represents a source of energy that should be utilised. The quality of the meat from 96 beef cattle which either consumed or did not consume this by-product was compared in two trials carried out 2012 and 2013. The animals, with an average live…
The aim of this study was to compare the supply of grass and the intake of three herds (test variants) over the 2012 and 2013 grazing seasons. The first herd received no supplement (control group G), whilst the other two benefited respectively from a barley (B) and whey (W) supplement. The quantity of grass offered…
In alpine-cheese production areas, whey represents an important source of available energy which is both largely untapped and problematic for the environment if it is not properly disposed of. Its utilisation by beef cattle was studied in two trials, each comprising 48 heifers and steers belonging to different breeds or crosses of beef breeds, and…
CIPC (or chlorpropham) is the most commonly used product for controlling potato sprouting during storage. A new technique involving storage in an ethylene-enriched atmosphere (the Restrain® process) has been recently implemented in Switzerland. The efficacy of these two methods was compared in Switzerland during three storage seasons over six potato varieties stored in different commercial…
A network of experimental fields in northern and western Switzerland was used to better understand the behavior of various cover crops in diversified environmental conditions. Several species were oriented towards soil cover in autumn (e.g. brown mustard). Others produced an important aerial biomass (e.g. sunflower). Some, with intermediate performance during autumn, had a good soil…
Herbicide resistance is a worldwide industrial agriculture problem that worsens from year to year. In certain northern European countries, black-grass is resistant to numerous different herbicides, and can scarcely be controlled in certain places. This phenomenon is also starting to emerge in Switzerland. Starting in 2011, and in order to monitor the appearance of new…
Mixed cropping of grain legumes with cereals is a promising approach to economic and resourceefficient domestic production of protein plants. Since 2009, FiBL has established field trials in cooperation with organic farmers with a view to jointly developing suitable production methods under Swiss conditions. A range of seeding ratios as well as different combinations of…
Generally speaking, cattle sheds are naturally ventilated buildings. Because of this, the situation is different on both the emission and impact sides than for animal housing with forced ventilation. This paper highlights methods contributing to the clarification of odour complaints. Using a case study, a process is explained with an analysis of the nuisance and…
Mostly, agricultural biogas facilities on farms in Switzerland exist in combination with animal husbandry. The proximity of these facilities to residential areas can lead to odour complaints from residents. Animal housing and outdoor exercise areas, feed and farmyard manure stores, as well as substrate and fermentation residue stores all figure among the diffuse emission sources.…
Mountain pasture areas in Switzerland are faced with a dual challenge: halting the advance of the forest, and dealing with the whey which is a by-product of alpine cheesemaking. Beef cattle could contribute to the sustainability of mountain pastures by increasing pasture pressure and reducing environmental impact through the use of the whey in situ.…
The effects of varying feeding regimes on chewing behaviour and faecal particle size distribution were investigated in an experiment with 23 lactating Swiss Fleckvieh cows. The herd was located at an organic dairy farm with a low concentrate feeding regime as required by the regulations of the organic association Bio Suisse. In a two factorial…
Molasses from the manufacture of beet sugar enables an improvement in the fermentation quality of beet-pulp silages. An in vivo trial with sheep was carried out at Agroscope Posieux in order to ascertain the digestibility of molassed pulp silages. Adult wethers (n = 4 per treatment; 83.9 ± 9.3 kg average weight) were given rations…
From 2012 to 2014, Agroscope conducted comparative trials on 17 varieties of tall fescue (Festuca arundinacea Schreber) and two varieties of xFestulolium krasanii at seven experimental sites. All varieties were grown in pure stands and in mixture with clover. The parameters assessed were dry matter yield, juvenile development, regrowth speed, general impression, competitive ability, persistence,…
The premise that global warming changes the conditions for crop production was investigated throughout Switzerland on the basis of a climate suitability for grain maize cultivation. Gridded projections1 of temperature changes for three time periods (2020–49, 2045–74, 2070–99) available from twenty climate-model chains for the A2 emissions scenario (i.e. the «business as usual» scenario) were…
Factors for calculating standard labour units (SLUs) are derived from cost/ performance calculations for paraagricultural activities found in business- management literature. The SLU factors specify the necessary labour input per CHF 10 000 of volume of sales or turnover, with three activity categories being distinguished. Leisure time and educational activities on the farm are highly…
