En este proyecto se evaluará el efecto de diferentes nanofertilizantes que se comercializan en la actualidad sobre diferentes cultivos para establecer dosis seguras que supongan una optimización en las recomendaciones de empleo de fertilizantes minerales y al mismo tiempo que no representen un impacto negativo para las propiedades del suelo. Se plantea realizar en primer lugar una caracterización exhaustiva de los materiales que se utilizarán en los ensayos. Asimismo, se realizarán ensayos de lixiviación en columnas de suelo a fin de evaluar la disminución de la lixiviación de nutrientes en comparación con los fertilizantes no nano. Posteriormente de realizarán ensayos controlados en cámara de cultivo e invernadero a fin de determinar dosis optimas de aplicación. Se comparará el rendimiento obtenido del suelo tratado con los nanofertilizantes con fertilizantes inorgánicos tradicionales. Así mismo, se analizará la composición química y nutricional de los productos hortícolas obtenidos para garantizar la seguridad y calidad alimentaria.

Evaluating the impact of nanomaterials application in agriculture
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.
