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 $150 to $400 per hour for complete site clearing, depending upon the machinery necessary for the job (usually including a large bull dozer); 2  Grading-sub-grading the area for a slab on grade is going to cost roughly $1.43 per square yard for a total of $100; and. This tends to have a life span of 10 to 30 years and will need treatment every six to ten years to maintain its good looks and durability. 2  This is known as a macadam treatment and will average around $2 per square foot, or roughly $1200 every six years.
