grasses) should be limited to mechanical clipping or shredding prior
to grass seed set, or to herbicidal application of 1-2 lbs. AI/Ac of
2,4-D low volatile ester or amine after the S-leaf growth stage on
grasses. Contact the SCS office for more specific weed control
recommendations.
Areas which have been denuded or eroded down to subsoil layers or
exposed rock should definitely be topsoiled, preferably to at least a
depth of 4-6 inches. This will greatly enhance the probability of
seeding establishment, vigor and success. The area should be
scarified where possible to permit better bonding between the applied
topsoil and the underlying soil base material, After scarification,
the topsoil should be uniformly spread over the area.
c) A soil test should be performed to determine the proper
fertilizer requirement in both types and amounts. In lieu of a soil
test, it is recommended to fertilize the seeded area with 40 pounds
per acre of available, elemental nitrogen and 20 pounds per acre of
phosphate. If phosporous is the primary nutrient need, the
fertilizer should be incorporated into the top 2-3 inches of soil
using a light disk or harrow implement prior to grass seeding.
Fertilizer should preferably be first applied well into the growing
season after seedling emergence and early growth, particularly when
applying nitrogen as tfie primary nutrient,
d) Prior to topsoil spreading, any banks or other slopes
of moderate or greater degree should be worked within reason to
provide as minimal a slope as possible, preferably 3:1 or less. If
. steeper slopes must be vegetated, erosion control measures such as
small, series terraces or benches, contour ditches or furrows, or
other similar structures will be necessary to prevent surface erosion
and sloughing during seeding establishment. If benches are necessary
for soil and slope stability, bench height above the next lower bench
shall not exceed 20 vertical feet. Rough areas should be smoothed to
permit easier seeding and mulching. All tillage, seeding and
crimping operations should be performed across the slope <i.e. on
contour where possible).
e) All roads and other similarly disturbed areas should be
graded or reworked so as to blend into or approximate the surrounding
landscape as closely as possible. Any man-made ditches or other
drainages should be filled or structured such that water erosion will
be prevented or minimized, and surface water runoff is properly
channeled at non-erosive slopes to non-erosive outlets.
Recommendations for erosion control structures and proper channel
grades will be provided upon request by the SCS.
4) Seeding mixture recommendations are provided for seeding to
be done after project completion as final reclamation. The seed
mixture, for its intended purpose, is felt to best represent an
optimum combination of factors including ease of establishment, soil
holding and stability characteristics, wildlife forage value, low
maintenance during and after establishment, commercial availability
in the local or regional area, and tolerance of warm, low-moisture
conditions, Please refer to form_CO_ECS=5s_Part_I_lattached), for
recommended species and seeding rates.
