Description

This work shall consist of furnishing and applying an initial app lication of fertilizer on a new surface and one or more

refertilizations after the growth has progressed sufficiently, all as shown on the plans or as ordered. Materials

Fertilizer shall be a standard commercial grade fertilizer conforming to all State and Federal rules and regulations and to the

standards of the Association of Official Agricultural Chemists. The analysis shall represent respective percentages of nitro gen, phosphoric acid, and potash. 2.1.1 Except as permitted, the analysis ratio shall be 1:1:1 for initial application and 3:1:2 for refertilization application. The analyses in Table 643 -1 are preferred. Permission to furnish fertilizer with an analysis varying from Table 643 -1 will be based upon reasons given in writing by the Contractor requesting such variances. Table 643-1 - Fertilizer Information Percent of Nutrients

Refertilization Minimum Application Rate Lbs Per 1,000 ft2 Measurement Factor 10-10-10 20.0 1.0 15-15-15 13.4 1.5 19-19-19 10.5 1.9 10-3-6 20.0 1.0 12-2-8 16.7 1.2 12-4-8 16.7 1.2 2.1.2 A minimum of 30 percent of the nitrogen in fertilizer used for refertilization shall be water insoluble (WIN).

All fertilizer shall be identified by labels and shall show the following:

2.2.1 When furnished as a liquid, the fertilizer shall be delivered in an appropriate container or vehicle, and shall conform to the pertinent sections of the Fertilizer Rules and Regulations issued by the New Hampshire Department of Agriculture. Construction Requirements

Fertilizer shall be uniformly applied by either the dry or hydraulic method specified in 644.3.5. When the dry method is

used, special care shall be taken to thoroughly work the fertilizer into the soil. 3.1.1 The rate of application shall be based upon the nitrogen content and shall be a rate between 2.0 and 2.2 pounds of nitrogen per 1,000 square feet. See Table 643-1 for typical application rates.

Unless otherwise ordered, not less than three months shall elapse between the initial fertilization and the refertilization. No

refertilization ordinarily will be allowed between November 1, or when the ground has frozen, and the following April 1, or between June 1 and the following September 1. Refertilization will be allowed between August 15 and 31 only when it is determined that the permanent grasses have developed well and few weeds have appeared, and such refertilization will not tend to promote the growth of noxious weeds. Method of Measurement

Fertilizer will be measured by the pound or by the ton, and in accordance with 109.01, on the basis of weight slips or delivery

slips forwarded to the Engineer, but not to exceed the maximum rate specified or ordered. Measurements by the ton will be made to the nearest 0.01 of a ton. 4.1.1 The quantity for payment will be the product of the accepted quantity used and the appropriate measurement factor from Table 643-1.
