Mesocosms for soil-plant-insect interactions
A total of 40 mesocosms are distributed in five rows of eight mesocosms with a spacing of 0.5 m between them. In spring/summer we grow plant species that are currently expanding their range within Europe and species that belong to the same genus while being native in the Netherlands.

Nematode extraction & determination
Nematode communities play an important role in soil ecology research. To analyse different type of plant-soil nematodes, NIOO has a facility for extracting soil and root nematodes by Oostenbrink funnel and mistifier.

Soil ecotron
The ecotron consists of 60 cilinders with intact (non-disturbed) sand, peat or sea clay cores (20 each). For each soil treatment, ten of the cilinders are inoculated with soil from species-rich grassland with the same soil type. The other ten are inoculated with sterile soil from the same grassland. The cilinders are buried in an experimental garden.

Bacterial collection
NIOO has a collection of thousands of bacterial strains isolated from different (semi-)natural and agricultural environments. Most are bacteria isolated from soils, rhizosphere or plant parts, but aquatic strains are present as well.

ArcticMigrants - Arctic migratory birds pushed over the edge?
Due to its favourable location, the Netherlands harbours at times large numbers of migratory birds, and bears an international responsibility to accommodate them.

Smart natural enemies for sustainable pest control
Parasitoids are key natural enemies that contribute to biological control of economically important pests in both agricultural and natural ecosystems. They are however not always efficient in finding the pest insect in the greenhouse because the (mass-)rearing conditions differ from the greenhouse environment in which they are released. This reduces parasitoid motivation and efficiency to search for herbivore insect pests.

Using soil bio-inocula to enhance tomato and strawberry pest resistance and production
Inoculation of plants or soil with consortia of beneficial soil organisms is a increasing practiced to boost plant nutrition and defense in sustainable agriculture and horticulture, thereby reducing the need for high input of fertilizers and pesticides.
