Abstract
Applications of pig slurry were made to pasture at frequent intervals over a 4-year period. Earthworm populations were assessed after the last treatments had been applied. Total numbers—and those of deep-burrowing species—were greater on the high-slurry plots (5528 m3 per hectare) than on controls receiving inorganic fertiliser. Approximately 212 kg per hectare of copper and 150 kg per hectare of zinc were applied by this high rate of slurry.
