11 <br />3. Multiply the number of acres times the adjusted yield <br />predicted for each soil type. <br />4. Add the products of the multiplication performed in step <br />3. <br />S. Divide the total value obtained in step 4 by the total <br />acreage for the agricultural group. The quotient will <br />represent the adjusted weighted average yield for the <br />agricultural group. <br />6. Convert the adjusted weighted average yield for <br />agricultural group 1 to a relative value by dividing that <br />yield by itself (88/88 x 100 = 100). The relative values <br />of agricultural groups 2 -7 are then calculated by <br />dividing the adjusted weighted average yield of each <br />agricultural group by that of agricultural group 1 (Group <br />2 = 75/88 x 100 = 84). <br />The relative values for the Orange County agricultural groups <br />are shown in Table 3 and Column 10 of Table 2. <br />APPLICATION <br />When a decision is to be made about whether or not to acquire <br />the development rights on a farm, the average relative value of a <br />site must be calculated. To determine the average relative value, <br />the following procedure is used: <br />1. Locate the site on a soil survey map and determine the <br />kind of soils on the site. <br />2. Determine the acreage of each soil and the appropriate <br />agricultural group for each soil. <br />3. Multiply the number of acres of soils in each <br />agricultural group times the assigned relative value on <br />Table 2. <br />4. Add the products of the multiplication performed in step <br />3. <br />5. - Ovine the total value obtained in step 4 by the total <br />.- acreage on the site. The quotient will represent the <br />average relative value of the site. <br />To illustrate the application of this procedure, the relative <br />values of the farms of each current member as well as one former <br />member of the Agricultural Districts Advisory Board were <br />calculated. Only open land (pasture and cropland) and only that <br />portion of a farm contiguous to the homestead were considered in <br />the calculations. <br />Three of the farms are dairy operations (Nutter, Walters, and <br />Hogan), one (Strayhorn) is a swine and beef operation, and one <br />
