Although the rules regarding application of manure on snow-covered and frozen ground are out for public comment, you need to know the law is effective. With that law comes dates regarding application restrictions and the first date you need to be aware of is right around the corner. As of December 21 liquid manure from a confinement feeding operation can not surface apply manure on snow-covered ground. An exception to this rule is if the liquid manure can be injected or incorporated on the same day.
