Soils Information (783.21) <br />Information should be provided on the present Ind potential <br />productivity of existing soils. (Estimates can be obtained <br />from the SCS or from the USDA).

Soil sampling sites should be <br />identified on the soils map. ' <br />Soil information is too general in nature. Itlneeds to be <br />specific for McClain Canyon. For example, on page 4-35 of <br />the application it is stated "the horizoh may die only a <br />few centimeters or several meters thick." We require the <br />- exact depth of the soil on the site.
