La baja eficiencia en el uso del agua que tradicionalmente conlleva el cultivo del arroz es un handicap importante en el marco de gestión del agua en las comunidades de regantes de nuestro territorio, a menudo con una diversidad de cultivos importante. Muchas veces se asocia el cultivo del arroz a una forma de trabajar muy tradicional y peculiar que conlleva un consumo hídrico importante. Aunque el cultivo anoxico del arroz puede estar determinado por la necesidad del lavado de sales del suelo, en otras ocasiones responde únicamente a una gestión mas bien tradicional del cultivo. Este estudio permitirá obtener información para un posterior desarrollo de una estrategia agronómica de ahorro de agua en este cultivo, que permita un aumento de la eficiencia de esta agua gracias a utilizar el riego por goteo y determinar todos los cambios agronómicos necesarios para optimizar su producción y gestión. Estos cambios agronómicos pueden afectar a las distintas variedades y su adaptación al cultivo aerobio, los cambios tecnológicos que representa la siembra en seco, nuevas estrategias o productos para el control de malas hierbas, incidencia de las diferentes plagas, enfermedades y otras adversidades, estrategias de fertilización e incluso la cosecha del cultivo.

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.
