Recovery of compacted soils
Soil compaction due to agricultural vehicle traffic is recognized as one of the major threats to soil productivity, and soil ecological and hydrological functioning. In this video an overview of the different recovery techniques: mechanical (tillage), biological (“biosubsoiling”) and natural methods. In the past, the choice was often made to mechanically crack the compacted soil. This resulted in short-term improvement but recompaction occurred several years later. The main disadvantage of mechanical methods is that often the complete soil structure is disturbed, which strongly reduces the mechanical strength and moisture delivery capacity. Most promising for the long-term melioration of compacted arable land is the use of deep-rooting plants: biosubsoilers.

A Bio-inspired Multilayer Drainage System
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.

NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY
This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. 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).
Environmental monitoring within greenhouse crops using wireless sensors
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.
