• w Mulch Anchoring Tool - A tractor drawn implement especially designed to punch and anchor mulch into the surface soil. This practice affords maximum erosion control, but its use is limited to those slopes upon which the tractor can operate safely. Tool penetration should be about 2-3 inches. Pick Chain - This rolling spiked-chain implement can be operated on slopes of 3:1 gradient or steeper. It is attached to a tractor or truck which operates along the top of the slope. The pick chain can also be used for seedbed preparation and mixing fertilizer with soil. 6. Emulsified Asphalt applied as mulch material is blown from the applicator or as a separate operation, provides excellent mulch anchorage. Apply uniformly 0.04 gallons per square yard of rapid curing (R.S. -1 or R.S.-2), medium curing (M.S.-2) or slow setting (S.S.-1) depending on desired curing time. See the manufacturer's specifications. Emulsified asphalt should not be used in freezing weather since it contains approximately 50% water. Liquid asphalt may be used in freezing weather. V. Maintenance Maintenance is a vital factor in maintaining an adequate vegetative erosion control cover. Irrigation - If soil moisture is deficient, supply new seedings with adequate water if available (a minimum of 3-4" penetration) for plant growth until they are firmly established. This is especially true when seedings are made late in the planting season, in abnormally dry or hot seasons, or on droughty sites. Repairs - Inspect all seeded areas for failures and make necessary repairs, replacements, and reseedings within the planting season, if possible. If stand is inadequate, overseed and fertilize using half of the rates originally applied. If stand is over 60% damaged, re-establish following original fertilizer, seedbed preparation and seeding recommendations.
