718.03.1 Commercial Fertilizer: Uniformly broadcast fertilizer

over areas to be fertilized by either hand or machine methods. The rate of fertilizer application shall be as shown in Table 718-1. Table 718-1 Fertilizer Application Rates Type Fertilizer Pounds Per Acre 8-8-8 1000 12-12-12 667 13-13-13 615 16-16-16 500 Other balanced fertilizer may be used at the inverse proportional rate. After surface dressing, thoroughly incorporate fertilizer into the soil by light disking, harrowing, or roto-tilling. When dressing the surface by hand, the fertilizer may be applied before final raking and leveling.

718.03.2 Agricultural Lime: Uniformly spread agricultural lime at

a minimum rate of 2 tons per acre with a spreader. Apply lime prior to seeding, topsoil placement, and slab sodding. Lime may be applied in conjunction with fertilizer. After lime application, disk the areas and harrow or roto-till to incorporate lime or lime-fertilizer into the top 3 inches to 6 inches of soil.

718.03.3 Hydro-seeding: If using hydro-seeding methods, fertilizer

and lime may be included in the seeding slurry. When specified by the manufacturer, water soluble, liquid fertilizer, or liquid lime will be allowed for hydro-seeding product applications. Hydro-seeding will be measured for payment under Section 739.

718.04 Measurement.

718.04.1 Fertilizer: Fertilizer will be measured by the pound. The

estimated quantity shown on the plans is based on Type 8-8-8 fertilizer. If other types of fertilizer are used, the measured quantities will be multiplied by the factors of Table 718-2 to determine pay quantities. Table 718-2 Fertilizer Factors Type Factor 12-12-12 1.5 13-13-13 1.625 16-16-16 2.0 When using other balanced fertilizers, the factor will be determined by dividing the type of fertilizer by eight.
