Drie Utrechtse melkveehouders hebben in 2021 een mechanische vliegenval gebouwd en getest. Om de effectiviteit van de vliegenval te bepalen is in juli de vangst van één van de vallen nauwkeurig geanalyseerd. De mechanische vliegenval is goed inpasbaar op een (melk)veebedrijf. Een goed doordacht ontwerp is cruciaal voor een effectief werkende val, denk aan kleur en type borstels, gekozen materialen, licht-donker gradiënt en manier van afvangen. Het vee geleidelijk laten wennen aan borstels en uiteindelijk de val is erg belangrijk. De meeste plaag-vliegen worden afgevangen met deze val. Ongewenste bijvangsten blijven zeer beperkt. Een gecombineerde aanpak van bedrijfsmaatregelen, waaronder de mechanische vliegenval, kan leiden tot een flinke beperking en het achterwege laten van chemische vliegenbestrijdingsmiddelen.

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.
