摘要：Use of fertilizers has enabled a massive increase in crop production yields. However, this has come with severe negative externalities (e.g., greenhouse gas emission; eutrophication of non-agricultural ecosystems). Eco-innovations are one option to reduce the environmental impact of fertilizers without compromising fertilizer productivity. Although numerous eco-innovations in the domain of fertilizers are available, they have not yet seen a sufficient adoption rate. In this paper we explore main drivers for adoption of eco-innovations in the German fertilizer supply chain based on empirical investigations at three levels of the fertilizer supply chain: producers, traders, and farmers. We strive to take a “chain perspective†on environmental concerns and knowledge of fertilizer specific eco-innovations. The study was carried out in two steps: initially we conducted exploratory expert interviews with eight actors of the fertilizer supply chain. The statements generated thereby fed into a questionnaire answered by 57 participants stemming from fertilizer production ( n = 12), traders ( n = 34) and farmers ( n = 11) level. Findings suggest that drivers for eco-innovations are perceived differently by the various actors in the fertilizer supply chain. Overall knowledge on eco-innovations decreases downstream the chain. By taking a chain perspective on the adoption of eco-innovation, our paper contributes to the emerging body of literature on drivers for eco-innovation, and also maps out managerial implications of fostering the implementation of eco-innovations in the fertilizer supply chain.
