prairies

prairies,

generally level, originally grass-covered and treeless plains of North America, stretching from W Ohio through Indiana, Illinois, and Iowa to the Great Plains region. The prairie belt also extends into N Missouri, S Michigan, Wisconsin, Minnesota, E North and South Dakota, and S Canada. Many of the prairies of the world were formerly used for grazing purposes, but more and more are now coming under cultivation; hence they are often referred to today as the "vanishing grasslands." The soil of the prairies is basically a black chernozemchernozem
or black earth,
variety of soil rich in organic matter in the form of humus. It is generally a modified type of loess. True chernozem is black in color, but there are various grades, shading off into gray and chestnut-brown soils.
