The warm spring is letting farmers spread manure on their fields earlier than usual.
The Agency of Agriculture usually requires farmers to wait until April 1.
The concern is that manure spread onto snow-covered fields can wash into waterways when the snow melts.
But the unusually warm and dry weather has changed that this year.
Agriculture Secretary Chuck Ross says lifting the ban early will help farmers manage their manure resources and is in the best interest of Vermont waterways.
