I hear a lot of good stories about cover crops, but rarely have I seen some really good examples of how cover crops can actually aid no-till farming. I recently came across this YouTube Site, Johnson County Soil and Water Conservation District.
This site give some excellent and current examples of how to apply cover crops and the value they can add for spring planting.
Check out this video and see the benefits first-hand. This is really a very cool and informational video. (2 minutes total)
