El compostaje es una alternativa robusta y validada para la autogestión de los residuos sólidos orgánicos, pero su práctica no está extendida en el sector vitivinícola. Este proceso aerobio, degrada y estabiliza la materia orgánica hasta obtener una tierra similar al humus. La aplicación del compostaje para la autogestión de los residuos generados a nivel de cooperativa vitivinícola comportaría el beneficio directo de utilizar el compost como fertilizante orgánico en los propios viñedos, tanto en los cultivos convencionales como en los ecológicos. Este hecho comportaría la disminución de las emisiones y costes relacionados con el transporte de estos residuos, la disminución en el uso de fertilizantes inorgánicos y orgánicos, el cierre del ciclo de la materia orgánica y promover acciones para impulsar la economía circular, donde el residuo se trata como recurso. Además, contribuye al aumento de la materia orgánica de los suelos, que permite retener mejor el agua en el suelo, un aspecto fundamental para una mejor adaptación de estos cultivos al cambio climático.

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.
