Las altas concentraciones de amoníaco en el aire pueden provocar problemas en la piel, ojos, garganta y pulmones tanto en animales como en seres humanos. En casos extremos puede provocar ceguera, daños pulmonares e incluso muerte. En las granjas porcinas, donde el purín se acumula debajo de los slats con una gran concentración de amonio, la difusión de amoníaco en el aire es muy elevada y, a pesar de tener una ventilación adecuada, este amoníaco causa graves impactos en el bienestar de los cerdos. La implementación de tratamientos en los propios slats de las granjas como la adición de ácido o de materiales adsorbentes como las zeolitas, pueden reducir incluso mitigar las emisiones de amoníaco en las naves porcinas. Además, esta reducción de emisiones en granja podría tener impacto no sólo en el bienestar animal, sino en la productividad y calidad del producto final.

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.
