Concept for quality management to secure benefits of compost use for soil and plants Organic Eprints
Fuchs, J.G.; Berner, A.; Mayer, J.; Schleiss, K..
Use of quality compost can have an important positive impact on soil fertility and plant growth and health. For example, it increases soil humus and improves soil structure and suppressivity towards plant diseases. To obtain these positive results, it is important that the compost quality is appropriate for each use. If used inadequately, the impact of compost can also be negative. The compost producer should be responsible for the quality of his products, and has to communicate the properties of his composts to the users. But to be successful, the compost users have to communicate to the producers the manner in which the compost is to be used. To support compost producers and users in this process, the Swiss producers of compost and digestate published a...

Effects of reduced tillage in organic farming on yield, weeds and soil carbon: meta-analysis results from the TILMAN-ORG project Organic Eprints
Cooper, J.M.; Baranski, M.; Nobel de Lange, M.; BARBERI, P.; Fliessbach, A.; Peigne, J.; Berner, A.; Brock, C.; Casagrande, M.; Crowley, O.; Davide, C.; De Vliegher, Alex; Döring, Thomas F.; Entz, M.; Grosse, M.; Haase, T.; Halde, C.; Hammerl, V.; Huiting, H.; Leithold, G.; Messmer, M.; Schloter, M.; Sukkel, M.; van der Heijden, M.; Willekens, K.; Wittwer, R.; Mäder, Paul.
As part of the TILMAN-ORG CORE ORGANIC II project, data on the use of reduced tillage in organic farming systems from a range of field trials and the published literature was compiled. A meta-analysis was conducted to determine the impacts of reduced tillage on crop yields, weed pressure and soil organic C stocks. This paper highlights some of the key findings from this study.

Erhöhte Trockenstresstoleranz von Kleegras nach reduzierter Bodenbearbeitung Organic Eprints
Berner, A.; Nietlispach, B.; Frei, R.; Niggli, Dr. U.; Mäder, Dr. P..
Grass-clover leys are an integral part of organic rotations. We performed an experiment with reduced tillage (RT) and conventional tillage (CT) using mouldboard ploughing in a rotation in Frick (Switzerland) on a heavy soil and 1000 mm mean annual precipitation. The grass-clover mixture was sawn in autumn 2005 after uniform seed bed preparation with a rotary hoe in both tillage systems without ploughing. After emergence most of the clover seedlings collapsed in the CT plots due to draught, while they survived in the RT plots. This led to a much higher share of clover in the mixture under RT. Grass-clover yields were 29 and 23% higher in RT than in CT plots in the first and second year of cultivation in 2006 and 2007, respectively. Grass grown in...

Genetic variation for nutrient use efficiency in maize under different tillage and fertilization regimes with special emphasis to plant microbe interaction Organic Eprints
Messmer, M.; Berner, A.; Krauss, M.; Jansa, J.; Presterl, Th.; Schmidt, W.; Mäder, P..
Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides. To promote conversation tillage in organic farming systems, crop rotation, fertilization and weed control have to be optimized. In addition, crop varieties are needed with improved nutrient use efficiency (NUE) and high weed competitiveness or tolerance.

Pilot Experiments with Electrodialysis and Ozonation for the Production of a Fertilizer from Urine Organic Eprints
Pronk, W.; Zuleeg, S.; Lienert, J.; Escher, B.; Koller, M.; Berner, A.; Koch, G.; Boller, M..
Pilot tests were performed with a process combination of electrodialysis and ozonation for the removal of micropollutants and the concentration of nutrients in urine. In continuous and batch experiments, maximum concentration factors up to 3.5 and 4.1 were obtained, respectively. The desalination capacity did not decrease significantly during continuous operation periods of several weeks. Membrane cleaning after 195 days resulted in approximately 35% increase in desalination rate. The Yeast Estrogen Screen (YES), a bioassay that selectively detects oestrogenic compounds, confirmed that about 90% of the oestrogenic activity was removed by electrodialysis. HPLC analysis showed that ibuprofen was removed to a high extent, while other micropollutants were...

Potential of different composts to improve soil fertility Organic Eprints
Fuchs, J. G.; Baier, U.; Berner, A.; Mayer, J.; Tamm, L.; Schleiss, K..
Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. Some practitioners already make use of the positive effects on plant health. For example, they use composts to protect their plants against soil borne diseases in substrate, or to detoxify and reactivate soil after steaming. In order to estimate the potential of Swiss composts to influence soil fertility and plant health positively, we analyzed one hundred composts representative of the different composting systems and qualities available on the market. The organic substance and the nutrient content of the composts varied greatly between the composts; the materials of origin were the major factor influencing...

Tillage as a driver of change in weed communities: a functional perspective Organic Eprints
Armengot, L.; Blanco-Moreno, J.M.; Bàrberi, P.; Bocci, G.; Carlesi, S.; Aendekerk, R.; Berner, A.; Celette, F.; Grosse, M.; Huiting, H.; Kranzler, A.; Luik, A.; Mäder, P.; Peigné, J.; Stoll, E.; Delfosse, P.; Sukkel, W.; Surböck, A.; Westaway, S.; Sans, F.X..
The adoption of non-inversion tillage practices has been widely promoted due to their potential benefits in reducing energy consumption and greenhouse emissions as well as improving soil fertility. However, the lack of soil inversion usually increases weed infestations and changes the composition of the weed community. Weed management is still a main drawback for the wider adoption of reduced tillage practices. However, it is not entirely clear whether these changes in weed communities are a consequence of non random filters on the functional attributes of weed species and may thus affect the potential weed-crop competition relationship. Here, we analyse the changes in weed diversity, community composition, and the functional attributes of weed...

Tillage effects on weed communities in an organic winter wheat-sunflower-spelt cropping sequence Organic Eprints
Sans, F. X.; Berner, A.; Armengot, L.; Mäder, P..
Conservation tillage could provide environmental benefits to organic farming. However, potential weed problems often tend to discourage farmers from adopting it. The effects of tillage (reduced vs. conventional), fertilisation (slurry vs. manure compost) and the application of biodynamic preparations (with and without) on crop yield and on weed cover, diversity and biological attributes were investigated in a cropping sequence of wheat, sunflower and spelt. Total weed cover and perennial cover in reduced tillage treatments were two to three times greater than in conventional treatments. Monocotyledon cover in reduced tillage was three times that in conventional tillage in spelt, whereas the dicotyledon Stellaria media dominated in sunflower. Weed diversity...

Wheat yield and quality as influenced by reduced tillage in organic farming Organic Eprints
Peigné, J.; Messmer, M.; Aveline, A.; Berner, A.; Mäder, P.; Carcea, M.; Narducci, V.; Samson, M.-F.; Thomsen, I.K.; Celette, F.; David, C..
Organic farmers are interested in soil conservation by reduced tillage, techniques well known in conventional agriculture to protect soil quality and limit labor time and energy costs. However, organic farming and reduced tillage can modify weeds, soil structure, and thus soil nitrogen (N) mineralization which strongly influences wheat yield and quality. The main objectives of this study were to analyze how reduced tillage applied to organic wheat influenced (1) grain yield, protein concentration, and weed infestation; (2) deoxynivalenol (DON) contamination on grain; (3) technological quality parameters such as dry gluten, zeleny index, falling number, and gluten index; (4) protein composition (F1, F2, F3, F4, and F5 fractions, and UPP, gliadin/glutenin...
