Abstract

This dataset consists of a sampling campaign of earthworms in arable fields and field margins in the Southwest of the Netherlands. Samples were taken in September and October 2012 with a combination of two methods: handsorting a soil monolith of 20x20x20 cm, and formaldehyde solution (500 ml of 0.2% solution) pored after removing the material to be hand-sorted.

Keywords: soil biodiversity, earthworm, lumbricid, Lumbricidae, arable fields, field margins

Project details

Project title: Spatial distribution and dispersal of earthworm populations in a complex landscape - implications for soil ecosystem services
Personnel: Mirjam Pulleman, Joana Frazão
Funding: Netherlands Organisation for Scientific Research (NWO)
Study area descriptions/descriptor: Hoeksche Waard
Design description: Each of 15 farms (26 arable fields and 15 field margins) were surveyed. Samples were taken in September and October 2012 with a combination of two methods: handsorting a soil monolith of 20x20x20 cm, and formaldehyde solution (500 ml of 0.2% solution) pored after removing the material to be hand-sorted.
