Summary
En god bestand meitemark spiser seg gjennom 25 % av matjordlaget hvert år. De har krås, og mikroorganismer i tarmen. Dermed går omdanningen av organisk materiale mye raskere med meitemark i jorda enn uten. Meitemarken bygger opp humus (mold), og ekskrementene er langt mer næringsrike og tilgjengelige for planterøtter enn jorda rundt.
Additional Summary
A population of earthworms can eat its way through 25% of the top soil layer every year. The worms have a gizzard and microorganisms in their intestine. Because of this the decomposing of organic matter passes much faster with earthworms in the soil than withouth. Earthworms build up humus (complex organic molecules) and the excrements from the worms are important nutrition for plant roots.
