Soil Fertility Experiment (DVI Thyrow/Germany), Long Term Soil Organic Matter ExperimentEntry ID: HUB.IFP.Thyrow
Abstract: This experiment was started in 1938 at a site with a cool temperate
climatic regime. The soil is classified as a Leptic Podzol (FAO).
The rotations in the experiment are slightly different over the years,
and consist of: in 1938-54 2 year rotation potatoes,spring barley;
1955-60 3 year rotation potatoes,spring rye,winter rye; 1961-84 6 year
rotation sugar beet,spring barley,winter ... rye,potatoes,spring
barley,winter rye; since 1985 6 year rotation potatoes,spring
barley,winter rye,maize,spring barley,winter rye. Treatments are:
PK,NPK+/-organic manure; 3 N levels, 2 levels stable manure,green
The measurements made (data available), frequency, and methodology are
a) Vegetation measurements made and frequency
Total above-ground dry matter: Yearly;
N (since 1961)
b) Soil sampling
Details of soil sampling method: Soil auger; 20 samples/plot,
mixed; every plot; 0-30 cm depth; years 1957,77,82,83,91,92,93.
c) Soil measurements made and frequency
Total carbon: Annual since 1965.
Method of measuring total carbon: Wet combustion with K2Cr2O7.
Atmospheric inputs: N in rainfall since 1982.
d) Details of the meteorological station
Nearest meteorological station to the site: Own station (Thyrow)
which is 0 km from the site at coordinates 13deg18min E, 52deg28min
N. The meteorological station is automatic.
