This year, some producers have already started to harvest in very dry soils, and their risk of soil compaction is very low. But if the weather changes and it rains, producers will have to monitor soil conditions. When saturated, soil aggregates are 'lubricated' by water and readily reposition themselves through the air spaces, especially when heavy harvest equipment is used. In addition, farmers and equipment operators need to remember that compaction can occur during the application of manure or anhydrous when soil moisture exceeds field capacity (maximum amount of moisture retained by the soil).
