The cabbage fly flight model determines the start of egg laying as 160 degree-days based on the soil temperature (10 cm) or based on the standard air temperature (2 m above the soil surface) at the same location. Egg laying starts at 210 degree days. This model should be used in combination with direct observations of eggs in the field. This due to the large variability and to get an idea of the severity of the attack. The model uses daily soil or air temperature as a parameter. In areas with early crops the preceding season, the flight period can start earlier due to higher so il temperature under the covers.The DSS gives information about the risk of adult cabbage root fly flight activity. It can be seen that at 210 degree days (which is the upper threshold value), the risk of flight activity is high and it is likely that egg laying has begun on vulnerable brassica crops. Action should be taken to protect the crop, taking into consideration the observations in your own field.The DSS is created by NIBIO which is based in Norway

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.
