The model for the warning system for cabbage moth is based on the minimum temperature threshold and the requirement for accumulated day-degrees for the different stages of the cabbage moth. The accumulated degree-day model calculates forecasts for development of the cabbage moth through the summer, generates warnings for the time when eggs and small larvae can be registered in the field and the best time for treatment. The model uses soil temperature at a depth of 10 cm as a parameter. This means that it is not related to the presence or absence of cabbage moth in the field. The DSS gives information about the risk of cabbage eggs and small larvae that can be registered in the field and the best time for treatment. Yellow rectangles indicate that oviposition has begun and the farmer should make observations in the field. Red rectangles indicate the optimal time for treatment. Most larvae are small at this point and easily targeted on the outer leaves.Where can DSS be used. The DSS is created by NIBIO which is based in Norway. In order to work with this DSS, soil temperature at a depth of 10 cm should be available in the country of use.

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.
