Michon <br />Dear Mr. Michon; = <br />Attached are a soils map and a "Soil and Capability Map Summary* covering <br />the area which would be affected by the proposed Harney Lane Landfill <br />Site. <br />It should be noted that the effective depths and depths to claypans and/or:: <br />hardpans are not absolute, but vary within ranges. As a result, a depth on <br />the deeper end of the range could give the soil a better classification <br />than might be apparent from the summary. As a further example, a greater <br />depth to a limiting layer would also increase the available water holding <br />capacity. = <br />Another factor which has been found during our ongoing re -survey of County <br />soils has been that some of the pans formerly described as "claypans", are <br />in fact of a lighter texture and therefore more easily managed. <br />An intangible but measurable factor in land use is the degree of manage - <br />Ment of the soils. These soils, if properly managed by ripping, fertili- <br />zing, irrigation and other practices, are capable of significant produc- <br />tion levels. <br />
