The conference facilities, the restaurant and the bar are located in the main building called Bauhaus Building. For further information on Monte Verità and on connections to Ascona, please refer to the white CSF folder included in your conference bag. Conference rooms All lectures will take place in the Auditorium on the ground floor of the Bauhaus Building. All posters will be displayed from Monday to Thursday in the Balint Room, located on the first floor of the Bauhaus Building. We kindly ask you to take your poster down on Thursday morning and bring it home with you. Posters left at the venue after departure of the group will be discarded. Oral Presentations All talks are in plenary and are presented via Power Point or pdf slideshow on either a Windows or a Mac computer available in the Auditorium. The beamer has an additional third channel, so the use of your own computer is possible, but compatibility with the video system should be tested ahead of time. Members of the organizing committee will be available to assist you in uploading and testing your presentation. Chairpersons will monitor that the speakers stay within their allotted time. Poster Presentations Dimensions of poster boards are 180 cm (width) x 120 cm (height) and can fit A0-sized posters printed in both portrait or landscape format. Please refer to the numbered posters list in this book to find the assigned board for your poster. Two poster viewing sessions are planned: one on Monday and one on Wednesday, both from 17.30 to 19.00. Authors of posters listed in Session I are asked to stand by their posters on Monday, authors in Session II on Wednesday afternoon. “CSF Award” The CSF Award has been established in 2009 by the director and the scientific board of the Congressi Stefano Franscini. The Award will be conferred to the best platform presentation given by a young scientist during the conference, after review by a jury of jury members specifically appointed by the conference organizers. The CSF Award ceremony is scheduled at the end of the program on Thursday morning. Wireless and computer room There is a free wireless network in the Bauhaus Building and in the Semiramis Building. Please refer to the CSF folder you have received at registration for further information on the use of the wireless (password, settings, etc.). A computer room (equipped with Windows and Mac computers and one printer) is available for you 24 hours a day. The room is located at the ground floor level of the main building, just a few steps behind the Monte Verità hotel front desk. 4 DOK-Monte Verità – 6 – 11 October, 2019, Congressi Stefano Franscini, Monte Verità, Ascona, Switzerland Meals and refreshments Lunches and dinners (from Sunday dinner till Thursday lunch) will be served at the Monte Verità Restaurant, on the first floor of the Bauhaus building. Please refer to the timing indicated in the program for meals and arrive on time at the dining room. All coffee breaks will be served at the Bar Roccia, on the first floor of the Bauhaus Building. The Bar Roccia will also be open for you every evening from 21.00 to midnight. Only the participants who have booked the meals package in advance from the online Monte Verità’s platform can join the group for lunches and dinners. Excursion and conference dinner On Tuesday 8 October after lunch there will be a visit to two organic farms in the Magadino plain, followed by the conference dinner at the restaurant Castelgrande in Bellinzona. The farms are: (i) Demanio Cantonale, an organic farm owned by the Canton Ticino with 60 ha of arable crops, various experiments of No-Till and seed mixtures well adapted for dry conditions and newly planted orchard of chestnut trees for intensive production; (ii) Mäder Kräuter, a branch of Mäder Kräuter in Boppelsen (Canton Zurich), an organic farm with fresh herbs produced for supermarkets on 13 ha and a recently built glasshouse of 4 ha. We will depart from Monte Verità around 14.00 with 2 buses; the visits are planned to last approximately from 15.00 to ca. 18.00, and then we will reach the restaurant around 19.00 (directly after the visits, without going back to Ascona). We expect to return to Ascona around 22-22.30. We advise proper clothing depending on the weather forecast (we expect to spend 2.5 to 3 hours outdoor) and comfortable shoes for some easy walking on mostly flat terrain. DOK Excursion, Friday 11 October On Friday morning the two responsible scientists, Paul Mäder and Jochen Mayer, and colleagues will guide you through the DOK field experiment, where bio-dynamic, bio-organic and conventional cropping systems are compared in a four-fold replicated field experiment in 96 plots since 1978. It is located in the valley Leimen, a region characterized by loamy soil developed on deep deposits of alluvial Loess. An overview on associated ongoing or recently closed projects will be given (e.g., on drought stress, soil quality indicators, N2O emissions, N and C rhizodeposition, root carbon turnover, Deuterium studies, P-cycling). Principle investigators and PhDs will present new projects on soil organic matter quality and soil metagenomics. We will also discuss future research questions and potential collaboration with visitors. Disclaimer The conference organizers cannot accept any liability for personal injuries sustained, or for loss or damage to property belonging to congress participants (or their accompanying persons), either during or as a result of the congress. Registration fees do not include insurance. 5 DOK-Monte Verità – 6 – 11 October, 2019, Congressi Stefano Franscini, Monte Verità, Ascona, Switzerland Program Sunday, 6 October From 15.00 Arrival, registration 16.00 – 17.00 Welcome drink Introductory session Chair: Jochen Mayer 17.00 Welcome addresses Bernard Lehmann, former DG Federal Office for Agriculture, Switzerland Eva Reinhard, Head Agroscope, Switzerland Urs Niggli, Director FiBL, Switzerland 17.30 – 18.15 Keynote lecture Kate Scow, University of California Davis, USA Longterm impacts of management on soil Carbon, soil life, and agricultural resilience in Mediterranean agroecosystems 18.15 – 19.00 Keynote lecture Paul Mäder, FiBL, Switzerland The DOK long-term experiment – lessons learned from 40 years of interdisciplinary research 19.15 Dinner 6 DOK-Monte Verità – 6 – 11 October, 2019, Congressi Stefano Franscini, Monte Verità, Ascona, Switzerland Monday, 7 October 8.45 Congressi Stefano Franscini and Fondazione Monte Verità Welcome address Yield and yield development Chair: Erik Steen Jensen 9.00 – 9.30 Keynote lecture Jochen Mayer, Agroscope, Switzerland The performance of yields in organic and conventional cropping systems 9.30 – 9.45 Andrew Macdonald, Rothamsted Research, UK The Rothamsted Long-term Experiments 9.45 – 10.00 Bettina Leschhorn, Justus Liebig University Giessen, Germany Long-term effects of different farming and fertilization systems on biomass yields and nitrogen uptake of crops in the LTE “IOSDV” Rauischholzhausen 10.00 – 10.15 Evelin Loit, Estonian University of Life Sciences, Estonia Yield stability and nutrient use efficiency in wheat, barley, potato and field pea when comparing organic and conventional crop management from 2008-2017 10.15 – 10.30 Jaroslaw Stalenga, State Research Institute, Poland Environmental and yield performance of organic and conventional crop production systems in long-term experiment in Puławy (Poland) 10.30 – 11.00 Coffee break Nutrient flows and nutrient use efficiency Chair: Else K.
