The aim of the study was to demonstrate the feasibility of using hydrogen peroxide stabilized with silver (H2O2-Ag+) and selected fungicides for the treatment of hyacinth bulbs and to determine their effects on the development of fungi colonizing the substrate and bulbs and their impact on plant growth and development. Hydrogen peroxide stabilized with silver (H2O2-Ag+) and captan, pyraclostrobin + boscalid and methyl thiophanate + tetraconazole were used to treat hyacinth bulbs before planting, in the form of a 20 min soak. The effect of the treatment on the development of fungi on the bulbs and substrate was evaluated during rooting in the refrigerated storerooms and after placement in the greenhouse. Observations were also made on the effect of treatment on hyacinth growth and development. The study showed a significant effect of H2O2-Ag+ and fungicides used for the treatment of hyacinth on reducing the development of fungi on bulbs and substrate during the period of hyacinth rooting. It was found that H2O2-Ag+, at concentrations ranging from 2% to 10%, significantly increased the Chlorophyll Index and Nitrogen Balance Index. In some of the concentrations tested, it also increased petal width, inflorescence width, the number of flowers, leaf length, leaf width, plant quality, fresh weight without inflorescences and the dry weight of plants without inflorescences at some of the concentrations tested. It was shown that, for all fungicides used, flower diameter, inflorescence width, total height, leaf length, leaf width, plant fresh weight without inflorescence and plant dry weight without inflorescence were significantly increased compared to control plants. None of the treatments tested were phytotoxic to hyacinth.

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.
