The Windsor series consists of very deep, excessively drained soils formed in sandy glacial outwash. They are nearly level to very steep soils on glaciofluvial landforms. Slope ranges from 0 to 60 percent.
Permeability is rapid or very rapid throughout.
Mean annual temperature is about 50 degrees F., and mean annual precipitation is about 43 inches. Thickness of the solum ranges from 10 to 36 inches. Rock fragments, dominantly fine gravel, range from 0 to 10 percent by volume in the solum and from 0 to 15 percent in the substratum. Thin strata of gravel or thin subhorizons of coarse sand or loamy coarse sand are present in some pedons. Unless limed, reaction in the solum commonly is very strongly acid to moderately acid but the range includes slightly acid.
