Correcte verwerking van de waterstromen in de draintanks en substraatmatten om emissie te voorkomen tijdens de teeltwisseling: 1. Maak aan het eind van de teelt het drainwater zoveel mogelijk op, zodat de nieuwe teelt schoon kan starten. Onder voorwaarden kan een eventueel restant worden hergebruikt in de nieuwe teelt. 2. Voorkom dat slib uit draintanks en bassins zich ophoopt tijdens de teelt. Dit is een infectiebron voor pathogenen en microorganismen en het beperkt de silocapaciteit. 3. Restant water in substraatmatten bij teeltwisseling moet zo laag mogelijk zijn om lekkage van meststoffen en gewasbeschermingsmiddelen naar oppervlaktewater te voorkomen. 4. Let op andere delen van het systeem zoals verdeelstukken waar water in kunnen blijven staan.

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.
