(2000): The effect of fertilization and crop rotation on biological activity in a 90 year long-term experiment
BODENKULTUR. 2000; 51(2): 99-105.

Since 1906, a long-term field experiment has been carried out in Gro ss enzersdorf (Lower Austria) to determine the effects of monoculture, crop rotation and different fertilization methods on the yield of spring barley (Hordeum vulgare) and winter rye (Secale cereale). Additionally chemical and physical soil parameters have been recorded, but no biological data. To assess the biological activity in the soil of the 12 different: plots, we applied the VON TORNE's bait-lamina-test and investigated the abundance of enchytraeids as potential feeders on the bait substances. The bait-lamina-test showed a significantly lower biological activity in the unfertilized plots. A higher Feeding activity of soil-living animals could be demonstrated in the plots with monoculture versus plots with crop rotation. The consequence of dead fallow in the previous year was reduced biological activity and enchytraeid number.
