CAN THE VALUE OF SURFACE RESIDUE BE MADE ANY CLEARER !!!!
When the soil surface is left exposed -- IT ERODES !!
This past winter an unusual event happened where snow melted quickly and water moved off our fields. The soil was frozen rock hard, but in a short time period, the exposed surfaces warmed sufficiently to cause serious damage. All the cultivated fields in the area showed similar damage, but on a much larger scale.
