5.5.3 Harvest measurement method <br />A minimum of 3 years of Irrigated Cropland production will be measured in the reclaimed area. <br />This will begin in Year 8 after seeding. For each year, upon completion of a 1 st cutting in a field, <br />the number of bales cut from the field will be counted. A random number generator will be used <br />to select samples. A sample of at least 15 bales will be randomly selected and weighed according <br />to the procedures described below. No drying will take place, since no drying was accounted for <br />when the data was collected to determine the standard. <br />Bale weight measuring on the Morgan IC areas will be conducted using either a) a truck mounted <br />scale in the field for small bales ( <100 Ibs) or b) large bales ( >100 Ibs) loaded onto a semi -truck <br />and weighed at a certified truck scale. The truck scale will be either the existing one at the nearby <br />power plant, or, as an alternative, a local gravel mine, or, if none of these are available, WFC will <br />rent a scale for use on site. Any scale used will be certified with an accuracy of 1 pound or better. <br />For large bales weighed at a truck scale, bales will be individually weighed at the truck scale (i.e. <br />one bale on the back of a truck at a time). This will be a minimum of 15 bales. <br />Sample adequacy will be tested during field sampling using the formula in DRMS Regulation <br />4.15.11(2)(a), as follows: <br />t <br />n M _ ( Lg)2 <br />where: <br />n,,, = minimum sample size <br />s = Sample variance (n -1 degrees of freedom) <br />d = Precision (0.10 for cover and production; 0.15 for woody <br />plant density) <br />X = Sample arithmetic mean <br />t = The (a =.10) t -table value for a 1 tail t -test, n -1 degrees of <br />freedom (infinite degrees of freedom may be used if n> 30) <br />n = Sample size <br />(Revised: PR -06) 2.05.4(2)(e) - 47 <br />
