note = {In alignment with a transition to sustainable agriculture, alternatives for conventional harmful agricultural inputs are needed. Researchers in the field of plant production have emphasised that beneficial soil-microbes can offer support here. They occur in natural soils autonomously, and the plant and its surroundings can benefit from these microbes in a number of ways. Through their application in agricultural fields, they can also provide these benefits to food production. To make use of beneficial soil-microbes for sustainable agriculture, it is necessary to consider the perspective of two important stakeholders: the farmer’s perspective – as the one who needs to administer the microbes – and the consumer’s perspective – as the one who needs to consume a final product. This thesis aims to create a better understanding of mechanisms which impact the acceptance of these innovative plant production methods by farmers and by consumers, and of mechanisms important for relevant communications.
Firstly, a qualitative study was conducted with 36 farmers in Germany and the United Kingdom. Through this explorative, open approach it was possible to gain an in-depth understanding of farmers’ perceptions. Interviews with adopter, dis-adopter and non-adopter groups revealed, that irrespective of the farmers’ prior experience with similar innovations, the innovation was generally perceived as challenging.
Secondly, a quantitative study with training farms in Germany was conducted, which aimed to identify determinates of farmers’ intentions to use products based on soil-microbes. Based on 102 collected observations, various models were estimated to explain farmers’ intentions. The model which extended constructs from the theory of reasoned action with constructs from the technology acceptance model stood out as the superior model. Overall, the qualitative and quantitative farmer studies overlap in their findings on the importance of performance expectancy, and the identified stakeholder/referent groups which can facilitate the communication and diffusion.
Thirdly, an experimental online study with consumers was conducted to assess the impact of information framing on consumers’ acceptance of an end-product created using beneficial soil-microbes. When evaluating an unknown innovation, information can form a crucial basis for judgement. Thus, the objective was to investigate how framing (i.e., loss and gain framing) can effectively impact consumers’ attitudes and purchase intentions. Using the data of 754 German consumers, the results demonstrated that goal framing, thus the communication which describes the potential consequences of innovation application or lack of application, led to stronger responses than a control video with no such information.
The results of this thesis offer a first orientation for actors who may engage with future development and diffusion of innovations based on beneficial soil-microbes and other similar innovations. More broadly, it also offers insights about aspects which can facilitate the acceptance – and subsequent diffusion – of beneficial soil microbes in the future.},
