Soil Information for All Uses <br /> Soil Reports <br /> The Soil Reports section includes various formatted tabular and narrative reports <br /> (tables)containing data for each selected soil map unit and each component of <br /> each unit. No aggregation of data has occurred as is done in reports in the Soil <br /> Properties and Qualities and Suitabilities and Limitations sections. <br /> The reports contain soil interpretive information as well as basic soil properties and <br /> qualities.A description of each report(table)is included. <br /> Soil Chemical Properties <br /> This folder contains a collection of tabular reports that present soil chemical <br /> properties.The reports(tables)include all selected map units and components for <br /> each map unit. Soil chemical properties are measured or inferred from direct <br /> observations in the field or laboratory. Examples of soil chemical properties include <br /> pH,cation exchange capacity, calcium carbonate,gypsum, and electrical <br /> conductivity. <br /> Chemical Soil Properties <br /> This table shows estimates of some chemical characteristics and features that <br /> affect soil behavior.These estimates are given for the layers of each soil in the <br /> survey area.The estimates are based on field observations and on test data for <br /> these and similar soils. <br /> Depth to the upper and lower boundaries of each layer is indicated. <br /> Cation-exchange capacity is the total amount of extractable cations that can be held <br /> by the soil,expressed in terms of milliequivalents per 100 grams of soil at neutrality <br /> (pH 7.0)or at some other stated pH value. Soils having a low cation-exchange <br /> capacity hold fewer cations and may require more frequent applications of fertilizer <br /> than soils having a high cation-exchange capacity. The ability to retain cations <br /> reduces the hazard of ground-water pollution. <br /> Effective cation-exchange capacity refers to the sum of extractable cations plus <br /> aluminum expressed in terms of milliequivalents per 100 grams of soil. It is <br /> determined for soils that have pH of less than 5.5. <br /> 31 <br /> SUMMIT BRICK AND TILE COMPANY-EDMUNDSON CLAY MINE NOVEMBER 2023 <br />
