5. Preparation of Ground<br />
The areas over which the sod is to be placed shall be scarified or loosened to suitable<br />
depth. On areas where the soil is sufficiently loose, particularly on shoulders and fill slopes,<br />
the Department may authorize the elimination of the ground preparation.<br />
6. Fertilizing<br />
The device for spreading fertilizing shall be capable of uniform distribution of the material at<br />
the specified rate. The fertilizer shall be spread uniformly in one or more applications as<br />
specified below.<br />
a) An initial application of 400-500 pounds per acre.<br />
b) Unless otherwise directed, a second application of 400-500 pounds per acre shall be<br />
applied within 90 calendar days after the initial application on projects which have<br />
not been accepted prior to this time.<br />
7. Placing Sod<br />
Whenever a suitable length of roadway has been graded and is ready for sodding, the<br />
contractor shall, when directed by the Department, proceed at once with the sodding of the<br />
available areas. Sodding shall be incorporated into the project at the earliest practical time<br />
in the life of the contract. No sod which has been cut for more than 72 hours shall be used<br />
unless specifically authorized by the Department after careful inspection thereof. Any sod<br />
which is not planted within 24 hours after cutting shall be stacked in an approved manner<br />
and maintained properly moistened.<br />
Sodding shall not be performed when weather and soil conditions are, in the Department's<br />
opinion, unsuitable for proper results.<br />
The sod shall be placed on the prepared surface, with edges in close contact, and shall be<br />
firmly and smoothly embedded by light tamping with appropriate tools.<br />
Where sodding is used in drainage ditches, the setting of the pieces shall be staggered,<br />
such as to avoid a continuous seam along the line of flow. Along the edges of such<br />
staggered areas the offsets of individual strips shall not exceed six inches. In order to<br />
prevent erosion caused by vertical edges at the outer limits, the outer pieces of sod shall be<br />
tamped so as to produce a featheredge effect.<br />
On areas where the sod may slide, due to height and slope, the Department may direct that<br />
the sod be pegged, with pegs driven through the sod blocks into firm earth at suitable<br />
intervals.<br />
Any pieces of sod which, after planting, show an appearance of extreme dryness shall be<br />
