rage [. Exhibit J Mulching - The rate of 4000 pounds per acre is the average rate for mulching but t e straw should not be applied before the seeding is completed. Crimping can be done with a disc but the results may be less than satisfactory. A crimper should be used whenever possible. Plastic netting is good on steep slopes when stapled in place over the mulch in lieu of crimping. Seeding - Seeding can generally be done anytime after October 15.
