ReMIX aimed at analysing and optimizing the functioning of species mixtures, also called intercrops, in order to help design sustainable and diversified cropping systems for both conventional and organic agriculture. The studied species mixtures were mainly cereals and grain legumes. Eleven multi-actor platforms (MAPs) were set up in ten countries in order to demonstrate potential performances and interests of species mixtures. MAPs were a rich picture of promising species mixtures embedded in local negotiations and adjustments by relevant actors securing developing effective solutions fitted to the social and economic context in which farmers operate. Several knowledge syntheses, new experimental and modelling studies have been carried out to determine how plant traits (e.g. root architecture and canopy morphology), cropping practices (e.g. plant density), and environment (availability of N, P and water, light quality) influence the performances of species mixtures as compared to sole crops for the capture of abiotic resources and the control of animal pests, diseases and weeds. Novel ideas and specific concepts were developed in order to support breeding for intercropping. As much as possible, we aimed at converting scientific results into practical tools and synthetic information disseminated not only to farmers, advisors, and other farming sector stakeholders, but also to policy makers.

Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
