A test of the possible reduction of the digging activity of moles in pastures by increasing soil nitrogen

The level of nitrogen fertilizer (140 kg N/ha) was found in this study to reduce soil pH and the weights of earthworms (Lumbricus rubellus) in the laboratory. Nitrogen fertilizer (70 kg N/ha; 140 kg N/ha) was applied to pastures in an attempt to reduce the densities of molehills of the Coast Mole (Scapanus orarius) in British Columbia.
