As the season approaches its conclusion and harvest conditions are most challenging, there are few things worth remembering to protect and sustain soil health. At this time, soil is susceptible to compaction due to rain and saturated soil conditions. Soils remain saturated longer at this time of the year since water use by crops is negligible and there is low water evaporation due to cool temperatures. Conventional tilled soil remain saturated longer than fields under conservation tillage since intense tillage destroys soil aggregates, resulting in reduction in water movement through the soil profile. A no-till system provides better, stronger and more stable soil structure, which allows water percolation deep into the soil profile to mitigate wet fall conditions.
