Factors influencing the vegetation of extensively managed meadows

The territories of species breeding in hedges or in wet habitats were more often than expected close to sites for ecological compensation. By contrast, species breeding in open farmland were more distant from them than expected. The territories of species breeding in bushes or trees were preferentially in hedges or close to extensively farmed meadows…

Development of a surface smear starter culture

The FAM has developed two new surface mixed-cultures for smear ripened cheeses. These cultures have proven to be successful in practice and can now be ordered from the FAM. Research work carried out with the objective of combating sticky smear yielded numerous data on its formation. These results were used by the FAM to develop…

A diverse crop rotation improves yields and economical parameters

In the trial «Chaiblen» at Tänikon (Switzerland), the effect on yields and economical parameters of a diverse, a cereal-dominated and a maize-dominated crop rotation was examined during 27 years. The evaluation of the years of comparison with silage maize and winter wheat in the three crop rotations showed, that a diverse crop rotation with two…

Effect of two cultivation intensities on yields and economical parameters

On a loamy soil in Tänikon (Switzerland) the project «Chaiblen» has compared two cultivation intensities – intensive (IS) and integrated (IP) – and three different crop rotations. Over the period of two five-year crop rotations from 1991 to 2000, yields were similar for clover grass in IS and IP. Maize yielded slightly less and cereals…

Lupin – an alternative crop

The cultivation of new sweet white lupin (Lupinus albus) and narrow-leafed lupin (Lupinus angustifolius), and the introduction of crop related subsidies turned lupins into an interesting alternative for Swiss farmers. A two year study was carried out at the Swiss Federal Research Station for Agroecology and Agriculture (FAL) at Zurich to compare different cultivars of…

Variety tests with winter wheat and winter barley under organic agricultural conditions

Concerning variety testing of winter wheat under organic conditions Swiss authorities offer a new possibility. With beginning in autumn 2001 and with a scheduled re-evaluation after three years the actual variety tests are declared as an official variety testing program. This means that in the future winter wheat varieties can be accepted for the Swiss…

Precious milk fat from the high lands

High land milk fat produced on swiss alps during summer months contains significantly higher amounts of unsaturated fatty acids than common summer milk fat. Also conjugated cis/trans linoleic acids and ?-3 fatty acids contents are markedly higher. This result obtained in a single alp study a few years ago could be confirmed in a follow-up…

Nitrate leaching in a crop rotation from 1981 to 2000

Using 12 lysimeters nitrate leaching was determined for the following crop rotation: Potato – winter wheat – sugar beet – spring wheat – corn – spring wheat – rape – winter wheat – gras-clover mixture (green manure before potato, corn and sugar beet). Under the climatic conditions of Zurich-Reckenholz (1000 mm annual precipitation, 400 mm…

Nutritive value of grassland plants: Energy and protein values

Energy (NEL) and protein values (APIE and APIN) of 10 important grassland species were evaluated based on digestibility of organic matter which was determined by the method of Tilley and Terry. Foxtail had the lowest (5,5 ± 1,0 MJ NEL/kg DM) and white clover the highest energy value (6,4 ± 0,5 MJ). During the first…

Milking without stress

Cows only achieve their full yield potential in an environment where they feel comfortable. The milking parlour plays an essential part in shaping this environment. Even when milking machines are installed according to ISO 5707, operators of new milking parlours often notice not only the advantages, but find signs indicative of unfavourable conditions: Cows are…

Pathogen elimination of potato seeds by using electrontreatment

The dressing of the epidermis of potato tubers by using accelerated electron treatment did not allow the elimination of two pathogens under latent or adhesive form found on the skin. Spore bales of powdery scab did not loose their vitality after the treatment. Inoculation of Erwinia chrysanthemi populations before electron treatment on the tubers did…

Grasshopers need ecological compensation areas

To examine the effectiveness on biodiversity of the direct payments for ecological compensation areas we rely on grasshoppers both as indicators for landscape change and as a small and singing element of biodiversity, however threatened from extinction. To compare the situation before and after the introduction of the ecological compensation areas (ECA) a repeated survey…
