A well-structured soil includes tiny pore spaces where roots can penetrate and air and water can pass. It is the ideal state for supporting the many forms of biological life in soils, including the plant itself.
However, certain farming practices like tillage can create or the loss of these pore spaces. This situation, commonly called soil compaction, results in a denser soil profile and less-fertile soil.
In the latest ‘Focus on Corn’ presentation, titled “Soil Structure and Compaction,” Dr. Paul Jasa, Extension Engineer at the University of Nebraska-Lincoln, helps users in the Corn Belt and High Plains to improve their soil structure and decrease compaction.
This two-part presentation covers tillage, farm machinery, implements, high traffic levels and the other major culprits of soil compaction. It also offers stunning examples of the effects these practices have on soil compaction and on crops.
This hour-long, two-part presentation is open access through June 30, 2015.

Webcasts on a variety of other crops can be found in PMN’s Education Center.
