The sold-out science festival for children 'Expeditie NEXT' took over the historic Dutch city of Franeker earlier this month.

Nearly 1000 'citizen scientists' sent in their observations this year on Soil Animal Days 2019. And a surprisingly high number of people tried to do something in return for the vital services these soil creatures provide for us.

Micro-organisms living inside plant roots team up to boost the plant’s growth and tolerance to stress. This research is featured this week in the scientific journal Science.

If you’re small, smells are a good way to stand out. A team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) has demonstrated for the first time that two different types of micro-organisms – bacteria and fungi – use fragrances, known as terpenes, to hold conversations. And that’s not all. “We actually believe that terpenes are the most popular chemical medium on our planet to communicate through.”

Sorghum is the fifth most important cereal in the world. In sub-Saharan Africa, many farmers rely on this grain for food and feed. But Striga, a parasitic weed, can have a devastating impact on crop yield. With an 8-million-dollar grant from the Bill & Melinda Gates Foundation, an international team will now explore the potential of soil microbes to offer crop protection. The Netherlands Institute of Ecology (NIOO-KNAW) is coordinating this 5-year project.

Tiny predators in the soil can literally sniff out their prey: soil bacteria, which communicate with each other using scent. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) has discovered that these predators - called protists - 'eavesdrop' on the bacteria's communication. It's a discovery that opens up perspectives for agriculture. The results are available online this month in The ISME Journal, from the publishers of Nature.

What soil creatures are living right under our feet? Find out in your own backyard on 4 October - or in your local park, on your green roof or even your balcony (!) - as the Netherlands Institute of Ecology (NIOO-KNAW) organises the first-ever 'Soil Animal Day', together with the Centre for Soil Ecology (CSE).

Woodlice have for the first time been dethroned as the most spotted soil animals in Dutch gardens. The third edition of the nationwide Soil Animal Days saw arachnoids seize the top spot, with earthworms a close second. A probable explanation for the shift is the extremely wet weather at the onset of autumn. Fortunately, that didn't stop some 600 enthousiasts from counting the soil animals in their gardens.
