A second way to estimate the cost of the soil erosion is by estimating the impact of soil erosion on yield. The analysis is similar to the CSR analysis, but the difference in yield is the measure of the impact of erosion. This analysis includes continuous corn and a corn/soybean rotation.t this rate, the range in cost to the land owner per acre per year would be from $2.75 to $6.45 an acre. There is considerable difference between soils and counties with respect to the loss in value caused by erosion.
1 The site condition in New Jersey required special foundation which cost $500,00 in 1985 dollars. 2  Using the ENR building cost index, estimate the 1985 cost of the grouting seal on a landfill described in Example 5-2, including the most likely estimate and the range of possible cost.hus, the total cost of boring will be between (2,880)(3) = $ 8,640 and (2,880)(10) = $28,800. The unit cost of Portland cement grout pumped into place is between $4 and $10 per cubic foot including overhead and profit.
