Soils
Terrain is gently sloping, broken by a rectangular gridwork
of roads and fields. Much of the land is drained by tile systems
and open ditches because the land has poor natural drainage.
Predominant soils are:
Clarion:
2-5 percent slope, very well drained, occurs on upland slopes
Nicollet:
1-3 percent slope, poorly drained, occurs between uplands and low areas
Webster:
0-3 percent slope, poorly drained, occurs on low-lying uplands
Research
Crops. The farm is a site for small grains variety tests, corn and specialty soybean breeding, studies of nitrogen fertilization rates and timing on corn and for breeding soybeans with resistance to soybean cyst nematode. Researchers conduct extensive tests on corn and soybean herbicides.
Soils. Researchers study soil fertility and soil management systems. Agronomists study nutrient requirements of area crops and apply nitrogen, phosphorus, potassium and lime to observe crop yield response to the nutrients.
Facilities
The farm has an extensive system of tile lines. A home garden
for vegetable production is used for demonstrations and a weed
garden helps teach producers to identify and control weeds common
to the area.
