Cooley Sand and Gravel , continued page 3 be anchored. One method is to use a straw crimper and "crimp " the mulch into the soil . This should help to control erosion until the grass becomes established. See attached SCS standards and specifications for MuLching. 5) Fertilizer: A soil test should he taken. to determine fertilizer recommendations before seeding grass. Fertilizer should be applied prior to or during seeding and should be mixed into the soil . 6 ) Grass Seeding: Grass seeding should be done between November 1 and May 1 . Seeding should not be done on frozen soil . The seedbed should be firm and weed free . After the land is seeded to grass , it should be covered with mulch. Double the rates , listed below, for broadcast seeding. The following is a seeding recommendation . PLS Grasses % of Mix Per Acre Western wheatgrass , Barton 20% 3 . 2 Streambank wheatgrass , Sodar 10% 1 . 1 Slender wheatgrass , common 10% 1 . 1 Switchgrass , Blackwell 10% 0 . 5 Little 'oluestem, ?astura 10% 0 . 7 Slue grama , Lovinston 20% 0 . 6 Sideoata grama , Vaughn 10% 0 . '% Cicer Milk vetch , Monarch 10% 1 . 3 Total Pure Live Seed (PLS) per Acre ? y Stockpiled topsoil ( when it will be stockpiled over two years) should be seeded to Fairway 'Wheatgrass at the rate of 6 pounds per acre pure Live seed. This rate is 'or a grass seed drill . For broadcast seeding, seeding rates should be doubled. Grass should be planted using a grass 'seed drill with agitators in the drill box , double disc with depth bands and packer wheels. Ninety-rive percent of the seed should me planted at a depth of 1/2 inch to 3/4 inch. When stockpiled topsoil for 6 months to 2 years , then an annual crop , such as wheat or forage sorghum should be seeded for erosion protection . Short term stockpiled topsoil could be protected with a mulch. 7) Weed Control : Weed control is necessary to insure a successful seeding. Weeds can be controlled by mowing or spraying chemicals. Mow weeds when they are 6 to 8 inches high , leaving a 3 to d inch stubble. Do not clip off the too of the newly seeded grass. Mowing should be done for at least two growing seasons . After the seeded plants have reached the four leaf stage , then appropriate herbicides may be used to control weeds. Any chemicals used will need to be used according to manufacturer 's labeling. 8 ) Grazing: The area should be protected and grazing should be prohibited until the grass has become established.
