These prairie-derived soils are also the most productive soils of Illinois — corn and soybeans are the main crops corn is the state vegetable, and popcorn is the state snack food. Every soil can be separated into three separate size fractions called sand, silt, and clay, which make up the soil texture. There are six main soil groups: clay, sandy, silty, peaty, chalky and loamy.
They each have different properties and it is important to know these to make the best choices and get the most from your garden. These types of soil can either absorb lots of water or evaporate quickly with mini droughts. The main reason Illinois has such fertile soil can be traced back to the last ice age. Because the glaciers stopped over central Illinois, much of that material was deposited on the state.

Illinois Cooperative Soil Survey. What is a Soil Survey? Additionally, excessively drained soils tend to warm early and generally undergo marked temperature fluctuations. Water and nutrient availability are also limited in poorly drained soils because oxygen deficiency limits the ability of roots to take up adequate water and nutrients.
With waterlogging, putrefaction sets in. Putrefaction occurs when partially decomposed organic matter accumulates, clogging soil pores and blocking root growth and the drainage of water through soil. Putrefaction produces toxic substances: reduced nitrogen, sulfur, metals, and organic fermentation products. Additionally, poorly drained soils tend to warm up slowly in the spring and reduce the length of crop growing seasons. Terms of use. Email the Web Administrator with questions or comments.
