Description
In the Netherlands, soil biological measurements were carried out in a nationwide monitoring program between 1997 and 2014. The purpose was to complement the obligations of the Biodiversity treaty of Rio de Janeiro (1992), by measuring soil biodiversity in a functional context. In total circa 450 locations were selected in a random stratified design, comprising 12 dominant combinations of land use and soil type. In The Netherlands 60 to 70% of the soils are in agricultural use, which is reflected in the distribution of the data. The 12 categories were sampled in a six-year cycle. Only 2 cycles could be completed entirely. The monitoring network was designed to give a cross-section through the soil ecosystem, from microbes to earthworms. Moreover, soil physical and chemical characteristics were measured. The sampling strategy was unorthodox, because the entire farm area was considered to be the unit of sampling.
In this dataset the average values out of six subsamples is given per square metre for: abundances, taxonomic diversity and biomass of earthworms (Lumbricidae) and potworms (Enchytraeidae). Eatrhworms were counted in 6 soil blocks of 20x20x20 cm. Potworms in 6 soil cores, 15 cm deep and 6 cm in diameter. In addition to the national monitoring program, data are available from (smaller) experimental fields. A general description of the monitoring program and methods is pubished in Rutgers et al. 2009 (European Journal of Soil Science, 60, 820-832. doi: 10.1111/j.1365-2389.2009.01163.x)
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,179 records.
3 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data
The Biological Indicator for Soil Quality (BISQ) is a multidisciplinary project in a cooporation of several research insitutes. The main object of the project is to develop quality standards for functional diversity of soil organisms outside protected area’s, to fill in the gaps in knowledge in the functional aspects of biodiversity. Because (systematically collected) historical data are missing and complete references for soil ecosystems are absent, a biomonitoring programme has been started within the abiotic Dutch Soil Quality Network. It consists of 10 categories of land use and soil type, each with 20 replica’s, resulting in 200 locations. The abiotic network has a cycle of 5 years, with 40 locations sampled and analysed each year. Additionally organic (biological) farming has been chosen as a reference, assuming that it provides a more sustainable form of agriculture. In principle each land use category is complemented with 10 organic farms. Biological indicators are derived from a soil food web approach. They link biodiversity with ecological processes like (potential) mineralisation of carbon and nitrogen, soil formation and stability.
