English Abstract Nematode fauna used as an instrument for assessing
biological quality of soils. A joint study of the Department of Nematology,
Agricultural University, Wageningen (biotic parametes). To assess the
quality of soils an ecological typology based on the free-living nematode
fauna is in development. Herefore knowledge on the relationship between the
presence of nematodes and the physical and chemical soil parameters is
essential. Fifteen different forest ecosystems spread on 30 locations were
sampled between 4/4/88 and 26/5/88. This sampling program covered all the
sandy soils of the Netherlands. In 71 samples were analysed: water content
; pH, texture, organic matter, nitrate, ammonium, total nitrogen, sodium,
calcium, potassium, magnesium, base capacity and CEC. The analysis of the
biotic parameters and the interpretation of the data will be published in
another paper.
