• 4.3.5.2 Seedbed Preparation and Mulching
Redistributed topsoil that has been stockpiled and substitute soil
reconstruction materials will undergo mechanical seedbed preparation.
Seedbed preparation on lands reclaimed with substitute soil materials
(i.e., previously disturbed with no topsoil available) are the same as for
topsoiled lands that are seeded (see 9.4.3). To test volunteer growth
under this permit about 50 percent of the area receiving redistributed,
livehandled, rotocleared, topsoil will not be seeded and about 50 percent
will be seeded using standard practices. Redistributed, livehandled
rotocleared, topsoil materials will undergo mechanical seedbed preparation
in those cases when they are to be seeded. Activities on redistributed
Rotocleared topsoils will be minimized in order to realize maximum growth
of volunteer vegetation.
The goal of seedbed preparation will be to establish a uniform
seedbed that is conducive to the germination and establishment of the
permanent seed mixture. Various methods may be used to prepare the uniform
seedbed, including, but not limited to, discing, plowing and chaining.
Such methods will be employed to break up large clods of soil materials in
an effort to ensure optimum soil to seed contact after planting operations
• have been conducted. Seedbed preparation methods may be employed either
singly or in combination at the discretion of P6M personnel.
Salvaged Rotocleared topsoils (livehandled and stockpiled) will not
require mulching after they are redistributed due to their high organic
matter content. Salvaged non-Rotocleared topsoil and substitute soil
reconstruction materials will have mulch applied through either mechanical
application or cover cropping. Mechanically applied mulch will consist of
either straw, hay or equivalent material and will be applied at a minimum
rate of two tons per acre. A Reinco mulcher or other suitable equipment
will be used for mechanical application of mulch. The application of
straw, hay or other suitable mulch materials may also be accomplished by
any other methods deemed suitable by P6M personnel for the mulch material
used, and the field situation and conditions under which it will be
applied.
Cover cropping will be accomplished by planting an annual species
that generally is incapable of setting viable seed during the growing
season at the mine. The plant species that may be chosen for cover crop
mulching purposes include oats, barley, wheat or hybrid sterile rye for
spring planting, and/or milo, millet, or winter wheat for summer and fall
• planting. Cover crop plant species may be used singly or in combination.
On site use of various cover crop species further indicates that even in
