Summary
Abstract: The ASKOV Long-term Experiments on Animal manure and Mineral
Fertilizers began in 1894. This area was first cultivated around
1800, and was previously open mixed heath and deciduous scrubland. The
Average climatic conditions at the experimental site are: minimum
annual temperature: 4.4 deg C; Mean annual temperature: 7.7 deg C;
Maximum annual temperature: 10.8 deg C; and Mean annual rainfall: 862
