In this video, Texas producers and researchers discuss how managing disturbance can help increase soil aggregation, prevent compaction, and increase soil health. Soil disturbance occurs in three different forms:
• Excessive biological disturbance through overgrazing, limiting plants’ ability to harvest carbon dioxide and sunlight
• Chemical disturbance through over-application of nutrients and pesticides, which disrupt essential soil food web functions
• Physical disturbance through tillage and compaction, which can eliminate pore spaces necessary to hold water and air. It can also cause wind and water erosion, ponding, crusting, and organic matter depletion Reducing harmful soil disturbance is a good way to start rebuilding soil aggregates, pore spaces, soil glue, and organic matter.
