Pilot crop area
245 ha
Selected Measures
Wide row in cereals
In this measure, winter wheat was sown in wider rows, with a maximum of 70% of the usual seeding rate. The sparse wheat crop allowed flowering weeds, such as chamomile, cornflower, and poppy, to establish within the crop on the relatively nutrient-poor sites.
Beneficial insect strips to subdivide large arable fields
By planting beneficial insect strips in cereals, the aim is to attract the natural antagonists (e.g. ladybirds and hoverflies as aphid killers) of cereal pests and thus reduce the use of insecticides.
Perennial flowering area with native wild plants
Perennial flowering areas are particularly valuable for insects, as they contain many native plant species and can therefore serve as a food source for a large number of insects.
An S-shaped strip in a multi-year flowering area
An S-shaped strip is a measure for protecting birds. By mulching or harrowing the strip twice a year, in spring and summer, the area is kept open, allowing birds to land more easily. The curved S-line provides partial concealment, making the open area less visible to predators.
Planting of 14 individual trees
Trees of different varieties were planted to increase the proportion of woody plants near the fields. Old native fruit varieties were chosen that bring added value for people and nature.
Deadwood in perennial flowering areas
Deadwood elements have been added to enhance the multi-year flowering areas. Positioning the deadwood upright supports insects that prefer this habitat, as standing deadwood is now rarely left in place.
Legume undersowing in cereal cultivation
Legume undersowing in winter cereals aims to reduce the use of fertilisers. In the project, the clover was sown at the same time as the cereals using a seed drill.
Wild bee hotel
The wild bee hotel was set up as a display for interested community members in the region. It provides information about how wild bees often inhabit sandy soils, embankments, or deadwood. The installation aims to raise awareness and educate visitors about this important topic.
Training and Other Activities
Training on the topic of wild bees and insect identification
Training on various insect-friendly measures in arable farming
Monitoring of wild bees to check the success of the measures
Inspection of flowering areas and expert discussion as well as development of
Practical demonstration of a modern sickle bar mower with an automated sharpening machine
Pilot Project Achievements
Measures that question the established principles of modern intensive agriculture were tested. This applies, for example, to the creation of beneficial insect strips to subdivide large arable fields. This reinterprets a goal that farmers have often pursued for decades – to create the largest possible monoculture areas – and changes it in favour of positive factors for biodiversity.
The pilot project provided an improved understanding of the value and background of different perennial flowering mixtures. As the farm managers can decide each year whether they want to plough up or not, many are prepared to wait and see, even if weed infestation is progressing, which means that the measure has the advantage of being highly flexible.
As part of the wild bee monitoring programme, 33 wild bee species were documented for the first time in Saarland. In addition to examining the effect of perennial flowering areas on the wild bee fauna, the monitoring thus made a decisive contribution to recording regional diversity.
