I’m very proud of this chapter, written with some great international colleagues, led by my amazing colleague @alixvidal.bsky.social and with illustrations by the equally amazing @tulca.bsky.social. Everything you always wanted to know about earthworms and enchytraeids as indicators of soil health!

De balans van vanavond: drie punten én nul kans dat de Baltische staten in geval van een Russische aanval een beroep zullen gaan doen op Nederlandse verdedigers. #litned

Zo leuk en weer eens iets anders: ik ben bezig met het schrijven van het voorwoord in een kinderboek over een regenworm! Een geweldig verhaal met prachtige tekeningen! Komt binnenkort uit, grote aanrader (zeg ik zonder commerciële belangen). boekenvankoko.nl/robbie/

Vreselijk nieuws, maar goed artikel. Hopelijk kan Europe financieel bijspringen. Maar degene achter de knoppen bij het NRC BlueSky account moet nog even een kop koffie drinken, want het leest nu alsof Donald Trump bewees dat de mens klimaatopwarming veroorzaakt.... Toch nog een Nobelprijs!?!?!

Er zijn idd eko slakkenkorrels die goed werken. Is volgens mij ijzerfosfaat met een lok stof. Enige probleem is dat de vogels in mijn tuin er verslaafd aan zijn dus die pikken ze allemaal op, tenzij ik er wat gaas over leg. Ik hou niet van bestrijdingsmiddelen, maar dit is onschuldig en noodzakelijk

Congratulations Dr. Enno!🎉

Dit is 1 van mijn go-to recepten (niet vegetarisch). Regel 1 is natuurlijk: niet te groot laten worden! Anders kun je er nooit tegenop eten en is bovendien minder lekker. Hier ook 2 planten, maar alleen omdat ik graag groene en gele heb. Eigenlijk is het teveel… www.jamieoliver.com/recipes/vege...

Onder zonnepanelen groeien planten slechter of niet, wat zijn weerslag heeft op de biodiversiteit en de kwaliteit van de bodem. De mate van het effect hangt sterk af van de opstelling van de panelen. Luuk Scholten doet daar onderzoek naar. www.resource-online.nl/index.php/20...

Another Timelapse movie in the making. We are so lucky to work with Wim, his Timelapse movies with us have done so much for illustrating the importance of soil biota. See this classic, for example. vimeo.com/246948827

Niet helemaal duidelijk, maar het heeft waarschijnlijk oa te maken met een partner vinden, en met je vlot voorbewegen. Beiden gaat een stuk makkelijker boven de grond dan in de grond.
