The seed mixture shown includes 15 pounds per acre of Regreen, a sterile hybrid of
winter wheat and native wheatgrass. This is used as a cover crop to help control erosion
in the early stage of vegetation development. This species will survive for two or three
years. Because it is sterile it does not produce viable seed and will therefore disappear
after serving its purpose. The Regreen is not included in the seeds per square foot total as
it is a cover crop and will not become a part of the final grass community.
A indicated in earlier discussion fertilizer should not be needed with these species of
grass. Fertilization would act to enhance weed growth. In addition it would create a
condition that would favor cool season species at the expense of warm season species.
The native vegetation in this area is a blend of cool and warn season species. Therefore
to produce the best match between the final vegetation on this site and the surrounding
areas, fertilizer should not be use except to correct nutritional deficiencies if they become
evident in the vegetation.
Weed control maybe necessary on this site depending on weather conditions during the
first two years of growth. If conditions are wet then weeds may become a problem. Under
normal to dry conditions weeds may still be present but not problematic. Weed control
will be by either mechanical or chemical means depending on the species that needs
control, Which method used will be left to the permittee.
Mulching should not be needed when using to proposed species of grass. Like fertilizer,
mulch tends to favor to cool season species. In addition the high carbon content of
mulches often makes it necessary to add fertilizer to avoid a nitrogen deficiency in the
soil. Mulch can help with the establishment of the seed it tend to distort the species
balance. In a dry land situation it is difficult to determine the rate at which mulch will
decompose. This makes it difficult to determine the amount of additional nutrients to be
added to the soil. If the decomposition rate is slower than expected then the additional
