MULCHING. Immediately after the limestone, fertilizer and seed has been applied to the soil, the seedbed shall be harrowed, dragged, raked or otherwise worked so as to cover the seed with a layer of Mulch shall consist of grain straw or other equally satisfactory material approved by the Engineer. Mulch shall be spread uniformly over the area by hand or mechanical spreader. The mulch will be applied at a rate that will allow some sunlight to penetrate and air to circulate but also partially shade the ground, reduce erosion and conserve moisture (approximately 65 bales per acre). Mulch shall be held in place by crimping the grain straw or by spraying emulsified asphalt to the mulch at a rate of 3.5 gallons per 1,000 square feet. Adequate precations shall be taken to prevent spraying asphalt emulsion on cars, fire hydrants, driveways, sidewalks, or other structures. The contractor shall clean any cars, fire hydrants, driveways, sidewalks or other structures which have been sprayed. PLAN NEW agg..
