SOIL SURVEY OF OUTAGAMIE COUNTY. 
derived largely from sandstone, the types are mostly of a 
sandy nature. The name used for a soil series usually in¬ 
dicates the locality where that particular series was first recog¬ 
nized and mapped by the Soil Survey. By uniting the soil class 
with the soil series we get the soil type which is the basis or 
unit of classifying and mapping soils. A soil type thus, is a 
soil which is uniform throughout its entire extent in texture, 
color, topographic position, and other physical properties, and 
having a distinct agricultural unity, that is, being adapted to 
the same crops, and requiring the same treatment. It is also uni¬ 
form in the source of material from which it is derived, and the 
mode of origin which, taken together, determine the chemical 
composition. Since the soil type is the unit in classifying and 
mapping soils, and the basis upon which experimental work 
should be conducted, every farmer should be familiar with the 
soil types on his farm, and their leading characteristics.
