Determination of soil biological activity of reclaimed mine spoil using the bait lamina-test

The study investigated the soil biological activity of reclaimed mine spoil using the bait lamina-test. The study sites represent a pine chronosequenc e with three different stand ages. The bait lamina-test was carried our usi ng two different mixtures of bait. Answers were sought to the following que stions: Is the bait lamina-test suitable for the determination of soil biol ogical activity of reclaimed mine spoil! Are there differences in feeding a ctivity between the different stand ages and are there differences in feedi ng activity between the two mixtures of bait? The results show that the bait-lamina test is suitable for the determinatio n of soil biological activity of reclaimed mine spoil. The feeding activiti es increase with stand age. However, there were no significant differences in feeding activities of the standard-bait mixture and a mixture called,,Fe rtigko-dermischung".
