Ecoregion: cool temperate; Slope (%): 0 - 2 %
The Lancaster Rotation, Wisconsin, legume cereal rotation began in
1967. The area is characterized by rolling to hilly landscapes, with
soil developed in loess deposits of variable thickness over bedrock
materials. The climatic region is cool temperate. The average
climatic conditions at the experimental site are:
Minimum annual temperature: 2.3 deg C
Mean annual temperature: 7.8 deg C
Maximum annual temperature: 13.2 deg C
Minimum annual rainfall: 447 mm
Mean annual rainfall: 845 mm
Maximum annual rainfall: 1130 mm
The soil is characterized as a Rosetta silt loam (fine-silty, mixed,
mesic Typic Hapludalf). The layers are: Ap 0-13 cm: 10YR 4/2 silt
loam, granular structure. A2 13-25 cm: 10YR 5/3 silt loam, platy
structure. B1t 25-36 cm: 10YR 5//4 heavy silt loam, subangular
blocky. B2t 36-97 cm: 7.5YR 5/4 silty clay loam, angular blocky
structure. B3 97-152 cm: 10YR 5/4 silty clay loam, prismatic
structure. C 152-178 cm: 10YR 5/4 and 10YR 6/2 silt loam, massive.
Dolomite rock below horizon C. The soil is moderately well drained.
The soil properties are:
Minimum depth of root limiting layer: 100cm
Approximate water holding capacity: 32.3 mm per 100 mm
Approximate cation exchange capacity: 180 mmol/kg
Approximate soil organic matter content: 2.7%
Approximate carbon:nitrogen ratio: 12
Approximate soil bulk density: 1.45 g/cm3
Approximate ground water level: 300 cm
Percent clay (i.e. particles less than 2 um): 17%
Percent silt (i.e. particles between 2 um and 50 um): 77%
Percent sand (i.e. particles between 50 um and 420 um): 6%
Approximate soil pH: 6.8
Approximate minimum soil pH: 6.8
Approximate maximum soil pH: 6.8
Method of determining soil pH: Unbuffered in water. Soil:water = 1:1.33
