<br />Annualized Beneficial NED Effects <br /> <br />COTTON <br />Likely yields are from Table 30. The variable harvest costs for cotton are <br />on Table 26. <br /> Operating Costs <br />Operation Machine Labor Service Materials Total <br />First Pick Cotton $ 16.44 $ 5.51 S $ $ 21.95 <br />Make Modules 2.35 2.49 0.66 5.50 <br />Second Pick Cotton 5.48 1.84 7.32 <br />Make Modules 0.78 0.83 0.05 1. 66 <br />Rood Cotton 26.25 26.25 <br />Haul 11. 97 11. 97 <br /> Subtotal S 25.05 $ 10.67 $ 38.22 S 0.71 $ 74.65 <br />Ginning 105.36 105.36 <br /> Total S 25.05 $ 10.67 $ 143.58 $ 0.71 $ 180.01 <br /> <br />Cotton seed current normalized prices for fiscal year 1987 does not pay for <br />the variable costs of ginning. Therefore, all variable harvesting costs for <br />cotton will be allocated to the cotton lint and none for cotton seed. The <br />average variable harvest cost for cotton lint is estimated to be SO.144 per pound <br />($180.01/1,250 pounds of cotton lint provides 50.144 per pound as variable <br />harvest costs). <br /> <br />WHEAT <br /> <br />Likely yields are from Table 42. The variable harvest costs for wheat are <br />f rom Table 38. <br /> <br /> Operating Costs <br />Operation Machine Labor Service Total <br />Harvest $ 6.32 $ 2.21 $ $ 8.53 <br />Haul 11.00 11.00 <br />Total S 6.32 $ 2.21 $ 11.00 $ 19.53 <br /> <br />The average variable harvest cost for ~heat is estimated to be $0.36 per Cwt. <br />(SI9.53/55 Cwt./acre provides $0.36 per Cwt.). <br /> <br />2! The estimated net yield benefits for the change between before and after <br />condition are computed by subtracting the variable harvest costs from the current <br />normalized prices received by farmers. <br /> <br />This analysis does not consider the leaching of fertilizer and plant nutrients <br />beyond the reach of roots. Several acre feet of water may be used beyond the <br />needs of plants. This water carries soluble plant nutrients. Four pounds of <br />nitrogen has been measured in an acre inch of leach water. Other soluble plant <br />nutrients may move at comparable rates. Leached plant nutrients become a part of <br />another problem, they add to the salinity of ground ~ater. There may also be <br />some reduced tillage with the proper application of conservation cropping <br />sequence and crop residue use. <br /> <br />- 35- <br />
