My field has overgrown grass in it. (1) Anyway, can I just lime on top of it? I don't care if it kills the grass, I just want to sweeten the soil. (2) Also, should I use pellets or some other form of lime for working as quickly as possible? Right now, I am going to lime a small area to test the No Plow and Extreme Biologic stuff to see how it comes up before doing the whole field.
