* "...A well-structured soil is made up of aggregates of varying sizes that allow maximum space for air and water (ideally about 20 to 25% for each by volume). These aggregates form as a result of physical forces: freezing and thawing cycles, wetting and drying cycles. Organic matter promotes stabilization of the aggregate particles. Decaying organic matter acts like a glue to hold soil particles together, much like flour moistened and used as paste. ..." *

Here it gives clues about what may happen over winter.

* "The Visual Soil Structural Assessment (VSSA) is a rapid, comprehensive visual tool in gauging the overall health and productivity of the soil, especially for the non scientist. ..."

"...We concluded that VSSA is a reliable detector of soil of poor soil health and compaction. Soil with the two organic matter treatments showed substantial improvements over the winter, while the control plot had a drastic deterioration in soil quality." *
