Needs for manure management and the need to solve fertilization problems led the OG Manure management tools to study different tools and equipment to improve efficiency in the planning and application of manure: - Use of conductimeters to determine the exact amount of nutrients in manure and soils to correctly plan the appropriate dose of manure to apply at the appropriate moment. - Use of brand spreaders for the application of manure since is a common practice in Catalonia. - Use of hoses for the application which improves fertilization efficiency and allows the application of lower doses. - Manure application during different phases of crop growth: (1) before sowing and (2) during first growth of crop. The study of these different tools and practices allowed to advise farmers about the best equipment and techniques for manure application on their crops, and it has generally been concluded that: - Conductimeters allow an accurate estimation of needed and available nutrients and allow an application planning for the correct amount of slurry at the correct moment of crop growth. - Use of hoses for the manure application allow nitrogen efficiency and achieve greater uniformity while reduces smells and ammonia volatilization. - Application of manure during first growth of crop allows to add nutrients at the maximum extraction moment, increasing its efficiency.

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.
