BRIDGING FARMER EXPERIENCE AND SCIENCE: LEARNING FOR AGROECOLOGICAL DESIGN OF SUSTAINABLE FARMING SYSTEMS Organic Eprints
Francis, Charles; Nicolaysen, Anna Marie; Morse, Suzanne; Breland, Tor Arvid; Lieblein, Geir.
Bridging the large gap between science and experience of farmers is a crucial focus for educators who are intent on developing learning programs featuring phenomenology and practical experiences. Agroecology is emerging as an integrative and holistic approach to study agricultural and food systems. Understanding lessons learned from indigenous systems and the ecological principles on which they are built, focusing on the uniqueness of place in design and practice of farming, shifting from a discipline-specific to a holistic systems perspective, and integrating the human dimension into study of farming and food systems are all essential to building effective bridges between farmer experience and science as we practice this in university research and...

BRIDGING FIELD EXPERIENCE AND ACADEMIA: AN INTERNATIONAL AGROECOLOGY DOCTORAL PROGRAMME Organic Eprints
Salomonsson, Lennart; Cuadra, Margarita; Tesfay, Girmay; Ssekyawa, Charles; Mendieta, Bryan; Francis, Charles; Lieblein, Geir; Breland, Tor Arvid.
Students interested in achieving advanced education in agriculture and food systems using holistic, integrated approaches can find MSc programmes in Agroecology that meet such demand at universities such as UMB in Norway and ISARA in France. Many students now seek opportunities to pursue a PhD degree using a systems approach across disciplines. Interdisciplinary research in Agroecology is embraced by a dispersed group of researchers around the world, and few universities have their own capacity to offer adequate PhD courses and supervision for such interdisciplinary PhD training. To design a new programme, we have established an international network of Agroecology researchers, advisors, and instructors from several universities in Europe, Africa, Asia...

Cultivating multi-cultural teams: lessons learned in the "milpa" of an Agroecology MSc course Organic Eprints
Morse, Suzanne R.; Lieblein, Geir; Breland, Tor Arvid; Francis, Charles; Nicolaysen, Anna Marie.
Traditional milpa polycultures of maize-bean-squash consistently have higher yields and are more resilient to stresses than monocultures. This synergistic outcome builds on species differences in physiology and morphology. In our agroecology program, the faculty work as milperos, intentionally developing multi-cultural teams that are capable of building upon their differences.

Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland Organic Eprints
Ringselle, Björn; Berge, Therese W.; Stout, Daniel; Breland, Tor Arvid; Hatcher, Paul E.; Haugland, Espen; Koesling, Matthias; Mangerud, Kjell; Lunnan, Tor; Brandsæter, Lars Olav.
Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) companion crop, (III) false seedbed, (IV) taproot cutting (V), plough skimmer and (VI) ploughing depth. Three factorial split-split plot experiments were carried out in Norway in 2007–2008 (three locations), 2008–2009 (one location) and 2009 (one location). After grassland renewal, more dock plants emerged from seeds than from roots. Summer renewal resulted in more dock seed and root plants than spring renewal. Adding a spring barley companion crop to the grassland crop often reduced dock density and biomass. A false seedbed resulted in 71%...

EVALUATION OF STUDENT REFLECTIVE DOCUMENTS IN AGROECOLOGY EDUCATION: A QUALITATIVE ANALYSIS OF EXPERIENTAL LEARNING Organic Eprints
Nicolaysen, Anna Marie; Breland, Tor Arvid; Francis, Charles; Lieblein, Geir; Morse, Suzanne.
This paper describes an evaluation of experiential learning in agroecology, based on analysis of learning outcomes as described by students in their individual Learner (Reflection) Documents. Galt et al. (2013) highlighted the importance of reflective essays in reinforcing experiential learning. Each fall semester since 2000, students in an agroecology course in farming and food systems at the Norwegian University of Life Sciences (UMB) have submitted a self-evaluation of their learning as well as the teaching process. Their Learner Document is based on a log the students write about their experiences in the field, including interactions with stakeholders on farms and in communities, and lectures and discussion sessions with students and facilitators in...

Soil fertility in three cropping systems after conversion from conventional to organic farming Organic Eprints
Bakken, Anne Kjersti; Breland, Tor Arvid; Haraldsen, Trond K.; Aamlid, Trygve S.; Sveistrup, Tore E..
Temporal changes in the scores of selected soil fertility indices were studied over six years in three different cases of organic crop rotation located in southern, eastern and central Norway. The cropping history and the initial scores of fertility indices prior to conversion to organic cropping differed between the sites. Crop yields, regarded as an overall, integrating fertility indicator, were in all rotations highly variable with few consistent temporal trends following the first year after conversion. On the site in eastern Norway, where conversion followed several years of all-arable crop rotations, earthworm number and biomass and soil physical properties improved, whereas the system was apparently degrading with regard to P and K trade balances...

Sustainable nutrient supply of organic farming challenged by specialisation Organic Eprints
Hansen, Sissel; A. Bleken, Marina; Løes, Anne-Kristin; Govasmark, Espen; Falk Øgaard, Anne; Breland, Tor Arvid.
Diverse production on each farm, with livestock density well balanced with crop production, has been the traditional way to maintain the soil fertility in organic farming systems. However, there is a trend of specialisation into stockless arable or livestock farms. Stockless farming is challenged by depletion of soil mineral reserves and soil organic matter, risk of large nutrient losses after green manuring, and dependence on nutrient supply from external sources. In this paper, we focus on these challenges to sustained soil fertility.
