Cold winter air is one reason that we have highly productive soil in Illinois and the Midwest. Temperature plays a major role in how much organic matter is present in soils. Soil organic matter is carbon-based material, such as organic substances given off by plant roots, that has been broken...
We have all heard the story of the Pilgrims landing at Plymouth Rock in 1620 and the harsh conditions endured during the winter. The following year, they learned, with the help of indigenous people, how to survive at this location. We probably also relate what they went through to what we see...
