Before you can repair these pastures, you need to know what your goal is for that pasture. Are you looking to improve for Fall forage or possibly for stockpiling? Or are you looking to have some summer forage production, knowing you’re going to be abusing it again next Winter/early Spring? Either way, there is a solution for both.
The first thing to do, no matter your goal, is to clean up the large amount of manure that has accumulated on these pastures due to the concentration of animals. Additionally, if you feed in bale rings, you’ll have large build-ups of trampled hay and manure. Both the animals and the rings must be removed to either spread this manure on the remaining pasture or haul it off to the compost. The issue with leaving this much manure in a concentrated area is it could affect the soil pH, and a soil test should be done to determine if this has occurred on your pasture. If the pH is too low is might require a fast-acting lime application to the top two inches of topsoil. The ideal soil pH for forage grasses and legumes is 6-6.5.
