T1 - Adapting a Participatory and Ecosystem-Based Assessment Impacted by the Pandemic: Lessons Learned With Farmers in Tajikistan JF - Frontiers in sustainable Food Systems N2 - The paper presents a systemic and participatory assessment approach and scrutinizes how methodological changes necessitated during the Covid-19 pandemic implicated the process and its outcomes. The approach was applied in rural Tajikistan to evaluate changes effected by a development project that promoted the enhancement of biodiversity and ecosystem services in agrarian landscapes. The central building block of the assessment consisted of participatory workshops in 2018 and 2020 with farmers and other stakeholders to develop a systemic knowledge map and to evaluate the promoted strategies based on local expertise. The methodological basis was MARISCO (adaptive MAnagement of vulnerability and RISk at COnservation sites), a holistic and participatory approach to ecosystem-based assessment and management that requires well-trained facilitators. While the activities in 2018 could be implemented as planned, major changes in the work plan were necessary in 2020 due to severe travel restrictions and social distancing rules. Conducting virtual workshops was not possible, as it would have excluded key stakeholders from the process. Instead of conducting a comprehensive assessment workshop guided by two German MARISCO facilitators as originally planned, a series of short and small workshops could be realized. These workshops were facilitated by Tajik scientists after receiving virtual training from their German colleagues. Although it was possible to bring the assessment to a satisfactory conclusion, the methodological changes revealed significant drawbacks. Radical simplifications of the methods were necessary that led to reduced depth of the assessment and missed learning opportunities for participants. Limited experience in workshop guidance by the new facilitators posed challenges to the participatory process and the quality of its outcomes. While the adapted method created training effects that would otherwise have been missed, it also put additional pressure on the capacities of local partners. Our experience during the pandemic offers valuable lessons learned for future applications of systemic-participatory approaches. Whereas, a complete shift to remote applications is problematic, there is a need to put greater emphasis on capacitating local partners. Methodological trade-offs are necessary for partially remote working processes, but principles of participation and systemic thinking should not be compromised.

Student tutors change into the role of teachers and organize lectures, excursions, and assignments at the Real-World Laboratory “Ackerbaum”—an agroforestry system in the federal state of Brandenburg, Germany. Students can learn about agroforestry systems, participate in research, and take practical action. The examination of the module is a scientific report linked to the experimental area. In this study, an attempt was made to verify the quality and impact of teaching formats in the ITL via the analysis of 53 reports created by 170 students as well as surveys among participants. For this purpose, indicators were formulated that capture the quality of scientific methods and the contribution to higher education for sustainable development. Students and tutors appreciate the open working atmosphere and the possibility to actively participate in the course; many leave the module motivated. Some even move toward transformation in agriculture professionally as, e.g., consultants in the field of agroforestry. As a transformative institution, HNEE offers with ITL a rare opportunity for practical application, scientific methods, and transdisciplinary collaboration with different stakeholders to work on future models to change today’s agriculture.

Little is known about the symbiotic potential of indigenous SNB in Central Europe and the interaction with an SNB inoculum from commercial products. The objective of this study was to quantify the capacity of indigenous and inoculated SNB strains on the symbiotic performance of soybean in a pot experiment, using soils with and without soybean history. Under controlled conditions in a growth chamber, the study focused on two main factors: a soybean cropping interval (time since the last soybean cultivation; SCI) and inoculation with commercial Bradyrhizobia strains. Comparing the two types of soil, without soybean history and with 1–4 years SCI, we found out that plants grown in soil with soybean history and without inoculation had significantly more root nodules and higher nitrogen content in the plant tissue. These parameters, along with the leghemoglobin content, were found to be a variable among soils with 1–4 years SCI and did not show a trend over the years. Inoculation in soil without soybean history showed a significant increase in a nodulation rate, leghemoglobin content, and soybean tissue nitrogen concentration. The study found that response to inoculation varied significantly as per locations in soil with previous soybean cultivation history. An inoculated soybean grown on loamy sandy soils from the location Müncheberg had significantly more nodules as well as higher green tissue nitrogen concentration compared with non-inoculated plants. No significant improvement in a nodulation rate and tissue nitrogen concentration was observed for an inoculated soybean grown on loamy sandy soils from the location Fehrow. These results suggest that introduced SNB strains remained viable in the soil and were still symbiotically competent for up to 4 years after soybean cultivation. However, the symbiotic performance of the SNB remaining in the soils was not sufficient in all cases and makes inoculation with commercial products necessary. The SNB strains found in the soil of Central Europe could also be promising candidates for the development of inoculants and already represent a contribution to the successful cultivation of soybeans in Central Europe.

Merr.) could provide more resilience to changing climatic conditions and, at the same time, reduce soil erosion, nitrate leaching, and weed density in the main crop. However, there are challenges in introducing no-tillage techniques in crop systems in Europe as there is little quantitative knowledge about the agro-economic impact. The objectives of this study were to evaluate the agronomic and economic impacts of three soybean cropping systems involving a rye (Secale cereal L.) cover crop prior to soybean, i.e., two no-tillage systems; either herbicide-free with crimping the rye or herbicide-based without rye crimping and one plough-based in which rye was cut as green silage. The impacts of these cropping strategies were compared in a three-year cropping system experiment at a research station in north-eastern Germany with and without irrigation. The following parameters were measured: (1) cover crop biomass; (2) weed biomass; (3) soybean plant density; (4) soybean grain yield; and (5) gross margin of the cropping system. The results showed that all three soybean cropping systems can effectively suppress weeds. System (C), the no-tillage herbicide-based system, produced the lowest rye biomass and highest soybean yield; system (B), the no-tillage herbicide-free/crimped rye system, produced the highest rye biomass and lowest soybean yield compared to system (A), the standard cutting/plough-based system. The differences in rye biomass and soybean yield observed between the three systems could be mainly attributed to the timing of the cover crop termination and the soybean sowing date. The gross margin was highest in system (C), due to the high soybean grain yield. The low soybean grain yield in system (B) resulted in lower revenues and gross margins compared to systems (A) and (C), although system (B) could be economically attractive in organic farming with higher prices for organic soybean. In the particularly dry year 2016, gross margins were higher when soybean was irrigated compared to the rainfed cultivation, due to significantly higher grain yields. Before recommending the application of the no-tillage with cover crop technique for the conditions tested in north-eastern Germany, more investigations on the benefits and risks of this technique are needed. Further research needs to focus on maintaining a high rye biomass as well as on ensuring an early soybean planting date. Optimizing the crimping and drilling equipment is still required in order to develop good management practices for no-tillage herbicide-free systems in European conditions.

The study combines semi-structured interviews with a biophysical characterization of farm systems. The results show that the assessed farming systems’ multifunctionality is essential to rural livelihoods while sustaining crop and tree diversity. While dry season crop diversity drives household’s sufficiency and capacity to respond to crop failure, medium-low sufficiency of production in more than a third of the assessed systems, as well as soil degradation in cereal fields lessen adaptive capacity. For their contribution to climate resilience, diverse and perennial cropping regimes should be supported and maintained.

T1 - Effects of shallow non-inversion tillage on sandy loam soil properties and winter rye yield in organic farming JF - Soil & Tillage Research N2 - Due to an expected improvement of soil quality and soil water storage, the substitution of mouldboard ploughing by reduced tillage was identified as a potential climate change adaptation measure for organic farming in a relatively dry region with a humid continental climate. In a field trial on a sandy loam soil in eastern Germany, reduced tillage was carried out to 6 cm soil depth by means of a ring cutter and compared to mouldboard ploughing with 25 cm tillage depth. In the present study, the influence of ring cutter tillage on soil properties was investigated for the first time. The effects of shallow ring cutter tillage on soil physical parameters, soil organic matter distribution, soil mineral nitrogen content, total nitrogen uptake by the crop, root content, and grain yield of organically grown winter rye (Secale cereale L.) were analysed in the uppermost 20 cm of a sandy loam soil and compared to those of mouldboard ploughing. Under ring cutter tillage, soil bulk density was in 8–20 cm soil depth by up to 15% higher than under mouldboard ploughing. In 9–15 cm soil depth, ring cutter tillage resulted in smaller contents of coarse macropores and mesopores, more micropores, and an 11% smaller available water capacity compared to mouldboard ploughing. The total nitrogen uptake by winter rye was in the ring cutter treatment by up to 44% smaller than in the mouldboard plough treatment. Root content was up to 209% higher in 1–6 cm soil depth and up to 71% smaller in 8–20 cm soil depth after ring cutter tillage than after mouldboard ploughing. Winter rye yield declined by 22–43% in the ring cutter treatment relative to the mouldboard plough treatment. Shallow ring cutter tillage resulted in a root growth-restricting soil compaction in the non-tilled soil layers below 6 cm depth and led to a limitation of nitrogen mineralisation until spring. Both effects likely caused the considerable reduction of crop yield. The results suggest that shallow ring cutter tillage in organic farming seems to be not suitable for sandy loam soils as long as the risk of a soil compaction-induced limitation of root growth and nitrogen supply cannot be minimised.

T1 - Patch cropping- a new methodological approach to determine new field arrangements that increase the multifunctionality of agricultural landscapes JF - Computers and Electronics in Agriculture N2 - Agricultural intensification decreased land cover complexity by converting small complex arable field geometries into large and simple structures which then were managed uniformly. These changes have led to a variety of negative environmental effects and influence ecosystem services. We present a novel small-scale and site-specific cropping system which splits a large field into small homogeneous sub-fields called ‘patches’ grouped in different yield potentials. A detailed workflow is presented to generate new spatially arranged patches with special focus on preprocessing and filtering of multi-year yield data, the variation in patch sizes and the adaptation of maximum working width to use available conventional farm equipment and permanent traffic lanes. The reduction of variance by the used cluster algorithm depends on the within-field heterogeneity. The patch size, the number of growing seasons (GS) used for clustering and the parallel shift of the patch structure along the permanent traffic lane resulted in a change in relative variance. Independent cross validation showed an increased performance of the classification algorithm with increasing number of GS used for clustering. The applied cluster analysis resulted in robust field segregation according to different yield potential zones and provides an innovative method for a novel cropping system.

Responding to this, and to the growing severity of global threats to agricultural and food systems, national and international research funders are increasingly demanding that funded projects achieve real-world transformation of farming systems towards true sustainability and resilience. This development is not only a new funding opportunity for researchers. Because separating the roles of knowledge generation and knowledge exchange with practice will often fail to achieve the necessary transformation, (at least some) researchers will need to engage in this transdisciplinary process of transformative agricultural research. As a consequence, the roles of these researchers need to shift towards stronger integration in farming practice, and deeper exchange with practitioners, adding a new key role to teaching and research. We argue that meeting the goals of the mission of transformative research in agriculture requires three essential freedoms. First, researchers need to be free to engage in this transformative research. This entails a freed mindset, which enables researchers to leave behind traditional roles, e.g. for true knowledge exchange, co-design of projects, and learning from farmers. In addition, there needs to be a stronger appreciation for transdisciplinary and transformative research in the research community, accompanied by a reduced pressure to perform in other currently dominating assessment categories. Second, farmers need to be free to engage in this process as well. Again, this requires an open mindset, e.g. to engage in, and learn from collaborative research, but also available funds and time to engage in the process. Third, transformative agricultural research needs freedom in the project structure and in administrative rules. This includes the permission to fail and to tolerate errors, so that the people involved in the process are able to learn from mistakes. In addition, this is required so that projects are not set up to avoid risks, and can really be transformative and contain innovative elements. Finally, funders will need to show trust in the parties and to reduce administrative burden. Within this framework we discuss the success factors and limitations of transformative agricultural research using examples from various recent national and international projects.

After jointly formulating ten core statements as their own practical principles for managing healthy farming systems, they went on to develop a training strategy to transfer this knowledge about promoting health on organic farms, describing a co-learning concept to collaborate with their peers in a long-term process. Most suitable, appropriate methods and optimal conditions were discussed for successfully spreading such complex tacit knowledge among other farmers, and crucially, for invoking change in behavior. One core concept emerged as being most critical for success – inspiration. It was the group members’ or peers’ ability to inspire, which, in their experience, was key to stimulate their own change of practices, motivate trials with new methods, or adopt a new perspective or philosophy for managing their farm. They described that it was not only the reading about different techniques, or seeing new machinery in action during a farmer field day – the actual spark that triggered their own action was in most cases personal interaction. The personal exchange and inspiration among peers, who have established a sound level of trust, who share their experiences, as well as passions and failures seemed to be most likely the key element of farmer learning. This was particularly true for learning and enhancing soft skills, such as intuition, gut-feeling or self-reflection – all essential skills for running healthy organic farms according to the farmer group. The farmers of this project series have attributed great value to learning with and from each other during a co-learning process, in particular when the group is regularly stimulated by and collaborating with interdisciplinary researchers who are embedded in this co-learning process. We could therefore conclude that not only participatory-/action research or multi-actor approaches, but agricultural research in general benefits from a deep connection and understanding between researchers and farmers, to successfully inspire change in practices, and the adoption of new philosophies and perspectives that trigger long lasting transformation.

The use of digital technologies can support this by designing and managing resource-efficient and context-specific agricultural systems. We present the Digital Agricultural Knowledge and Information System (DAKIS) to demonstrate an approach that employs digital technologies to enable decision-making towards diversified and sustainable agriculture. To develop the DAKIS, we specified, together with stakeholders, requirements for a knowledge-based decision-support tool and reviewed the literature to identify limitations in the current generation of tools. The results of the review point towards recurring challenges regarding the consideration of ecosystem services and biodiversity, the capacity to foster communication and cooperation between farmers and other actors, and the ability to link multiple spatiotemporal scales and sustainability levels. To overcome these challenges, the DAKIS provides a digital platform to support farmers' decision-making on land use and management via an integrative spatiotemporally explicit approach that analyses a wide range of data from various sources. The approach integrates remote and in situ sensors, artificial intelligence, modelling, stakeholder-stated demand for biodiversity and ecosystem services, and participatory sustainability impact assessment to address the diverse drivers affecting agricultural land use and management design, including natural and agronomic factors, economic and policy considerations, and socio-cultural preferences and settings. Ultimately, the DAKIS embeds the consideration of ecosystem services, biodiversity, and sustainability into farmers' decision-making and enables learning and progress towards site-adapted small-scale multifunctional and diversified agriculture while simultaneously supporting farmers' objectives and societal demands.

Therefore, this study aimed to compare three cropping systems of barley using Salsola turcomanica (ST), and Chrysopogon zizanioides (CZ) in three treatments of barley+ST, barley+ST+CZ and mono-culture of barley. Two-year field trials data were collected from November 2018 to October 2020 in two experimental sites using a Randomized Complete Block Design (RCBD) with four replications. The results of analysis of variance over two years indicated that the effects of year, location, and year by location interaction were significant (p<0.01) for all of barley’s yield components. Mixed cropping of barley with other species had no negative effect on barley traits such as grain yield, straw yield and harvest index. In addition, the mixed cropping of barley+ST and barley+ST+CZ in the first year produced 2.5 t/ha more forage yield than that mono-culture of barley. This was due to high production of Salsola (ST), in mixed cropping. In both years, yield of Salsola production was about 25% of whole produced biomass. Drastic reduction in rainfall in the second year reduced the obtained yield; so, there was no significant difference among three cropping systems in the second year. However, cropping systems of barley+ST and barley+ST+CZ produced about 1 t/ha more forage than that for the mono-culture of barley. Mixed cropping of barley +ST+CZ did not affect yield components of barley. Mixed cropping of barley with Salsola turcomanica could guarantee soil cover throughout the year and is recommended for forage production in rangeland in Iran.

Die Daten werden aktuell ausgewertet und die Analyse kann auf der Tagung vorgestellt werden. Y1 - 2022 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:eb1-opus-6736 N1 - Tagung, 2.-3.
