Infoblad 5 | Indirecte selectie voor smaak en voedingskwaliteit : Zaad Vast en Zeker
Omdat selectie voor voedingskwaliteit niet eenvoudig is, is gekeken naar de mogelijkheid om indirect voor voedingskwaliteit en smaak te selecteren. Dit zou bijvoorbeeld kunnen door selectie op bladvorm en plantgroei. Bij een aantal gewassen is hiernaar gekeken, met name bij Chinese kool en rode biet. Bij beide gewassen blijkt dat er duidelijke verschillen zijn tussen verschillende rassen. Uit eerdere proeven met rode kool bleek tevens dat de groeiomstandigheden indirecte selectie meer of minder effectief kunnen maken. En dan kan het ook gebeuren dat rassen anders op verschillende groeiomstandigheden reageren. Hieronder worden de bevindingen beschreven die zijn opgedaan tijdens het project Zaad Vast en Zeker

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.
