Downslope fertilizer movement in arctic tussock tundra
Slow release fertilizer pellets (NPK) were spread in June and July 1985, on the frost surface under an 8–20 cm thick layer of thawed tundra in the northern foothills of the Brooks Range, Alaska. The fertilizer was applied at a rate of 3.8 kg N, 1.2 kg P 2 O 5 , and 2.4 kg K to two, 10 × 0.75 m tusso...
