Illinois' ecology is in a land area of 56,400 square miles (146,000 km 2); the state is 385 miles (620 km) long and 218 miles (351 km) wide and is located between latitude: 36.9540° to 42.4951° N, and longitude: 87.3840° to 91.4244° W, [1] with primarily a humid continental climate.
It has been used as a water source in the Peoria area since at least 1892. By 1909, it was observed that groundwater levels at the North Field in Peoria fluctuated with the river stage in the Illinois River. The Sankoty aquifer extends beyond the width of the Illinois River valley and occurs beneath the uplands.
Much of this soil is called, appropriately, "Illite", and is the most common type of soil on the planet. The visible geology of the state is mainly Quaternary, with rocks buried deeply. The wealth of the state mainly arises from this abundance of soil and the favorable agrarian conditions it provides. Illinois is a major coal-producing
Illinois has received 3.41 inches of rain in the first half of July, 1.6 inches more than in the entire month of June, and leading to higher soil moisture across the state. Levels at 4 ...
Watersheds of Illinois is a list of basins or catchment areas into which the State of Illinois can be divided based on the place to which water flows.. At the simplest level, in pre-settlement times, Illinois had two watersheds: the Mississippi River and Lake Michigan, with almost the entire State draining to the Mississippi, except for a small area within a few miles of the Lake.
The maximum rate at that water can enter soil in a given condition is the infiltration capacity. If the arrival of the water at the soil surface is less than the infiltration capacity, it is sometimes analyzed using hydrology transport models, mathematical models that consider infiltration, runoff, and channel flow to predict river flow rates ...
soil type and structure. For example, sandy soil holds little water while clay soils have high water-retention rates; the amount of water used by the plants/crops; how much nitrate is already present in the soil. [3] The level of nitrous oxide (N 2 O) in the Earth's atmosphere is increasing at a rate of 0.2 to 0.3% annually.
Drummer soil is the most abundant and extensive soil in Illinois. It occurs over more than 1,500,000 acres (6,100 km 2) in the state. It is the most productive soil in the state. Corn and soybeans are the principal crops grown in Drummer soil. The average annual precipitation in areas of Drummer soil ranges from 32 to 40 inches (1,000 mm).
