Projects per year
To monitor the below-ground impact of novel bio-based economy related crops and processes on soil life, organismal groups with representatives in multiple trophic layers can be used as reporters. Nematodes are represented in three trophic levels, are highly abundant, and easily extractable from soil (Neher et al., 2005). Moreover, the availability of quantitative molecular assays for a wide range of nematode taxa (Vervoort et al., 2012), allows for a high throughput analysis of samples. Gaining detailed insight in spatial distributions of nematode taxa at hectare level is a prerequisite for (a) the selection of the most informative taxa, and (b) the design of strategies for the affordable and accurate sampling of relatively large areas. To address these two issues for the three main soil types in The Netherlands, namely marine clay, river clay and sandy soil, a geostatistical approach was used. Results will be presented from a first experiment in which we determined the effects of different ways to collect composite samples on the output accuracy. As a next step we present a geostatistical sampling approach to investigate spatial distribution of nematode taxa in arable fields across The Netherlands.
