Effects of nitrogen fertilization on the abundance of enchytraeids and microarthropods in Scots pine forests
The effect on the abundance of enchytraeids and microarthropods of the nitrogen fertilizers, ammonium nitrate and urea, was studied. The experimental sites were three Scots pine stands in central and northern Sweden. Doses of fertilizers were similar to those used in practical forestry in Sweden but...
