EXECUTION
The CONTRACTOR shall give the PROJECT MANAGER at least two (2) days
notice of the time and place of starting his revegetation operations
and shall continue to advise as to the schedule of operations.
Revegetation may take place at the completion of the work at an
individual site if the CONTRACTOR so desires.
Immediately prior to seedbed preparation, fertilizer shall be
uniformly applied over the areas designated for seeding, and
immediately incorporated into the soil by tillage methods as
discussed below. ._
Commercial Fertilizer Commercial fertilizer shall be commercial
grade diammonium phosphate (18-46-0) and free flowing, suitable for
application with hydraulic or pneumatic type equipment or fertilizer
spreaders and conforming to applicable Colorado State Fertilizer
laws. Caked or lumpy fertilizer will not be accepted. The
CONTRACTOR shall furnish a supplier's certificate of analysis and
weight. All fertilizer shall be in a form readily available to
plants. Commercial fertilizer shall be applied at a rate of 200
pounds per acre.
Seedbed Preparation The seedbed shall be firm. Miscellaneous
mining debris, trash, weeds, and other debris that will interfere
with seeding operations shall be removed or disposed of as approved
by the PROJECT MANAGER. Areas that are tilled or gullied shall be
smoothed to the extent that the rills and gullies blend with
adjoining surfaces.
On sites where equipment can operate, the seedbed shall be
adequately loosened (4 to 6 inches deep) and smoothed. Chiseling,
discing, harrowing, or cultipacking may be required. Work shall be
done on the contour where practicable. Slopes too steep for the
above operations shall be tracked up and down slope with a crawler
tractor.
On sites where equipment cannot operate, the seedbed shall be hand
raked or otherwise prepared by hand by scarifying to a minimum depth
of one (1) inch to provide a roughened surface so that seed will
stay in place.
Seedbed preparation shall be suspended when soil moisture conditions
are not suitable for the preparation of a satisfactory seedbed as
determined by the PROJECT MANAGER.
Seed Mixtures The CONTRACTOR shall be required to supply the seed.
The seed mixture designated below shall be uniformly sown over the
areas to be vegetated at the minimum rates per acre indicated below.
Seeding shall not be done if the ground is frozen. All rates are
