De groenterassen die De Beersche Hoeve teelt en ontwikkelt zijn zaadvast. Dat wil zeggen dat uit het zaad van deze rassen planten groeien met dezelfde eigenschappen als de ouders, maar met kleine variaties. Net als in de natuur. Tuinders die de zaden kopen van deze rassen, kunnen uit de groenten die daaruit groeien zelf weer nieuw zaad oogsten. Ze kunnen daarbij selecteren op de eigenschappen die het beste passen bij hun omstandigheden. Zo helpt De Beersche Hoeve tuinders om onafhankelijk te worden van de multinationals en dragen ze er aan bij dat zaden beschikbaar blijven voor iedereen. De Beersche Hoeve neemt je in dit infoblad mee in de wereld van zaadvaste en hybride rassen.

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.
