Esparcimiento de purines con bajas emisiones mediante la aplicación de purines directamente sobre el suelo o bajo la capa de hierba
La aplicación de purines en función de las necesidades de las praderas significa aplicar los purines en el lugar y el momento adecuados para proporcionar nitrógeno fácilmente disponible (es decir, nitrógeno amoniacal) que favorezca el crecimiento de las praderas y aumente el contenido de materia orgánica del suelo. El uso selectivo de los purines puede reducir en parte la necesidad de utilizar fertilizantes químicos de alto consumo energético basados en insumos no renovables. El uso de equipos de esparcimiento de purines de bajas emisiones (LESS) es una forma de reducir las emisiones de amoníaco, mejorar la calidad del agua, reducir los olores y aumentar la eficiencia medioambiental y económica del cultivo herbáceo.

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.
