Alfisol soil description sheet. USDA soil taxonomy ( ST) developed by United States Department of Agriculture in several levels: Order, , the National Cooperative Soil Survey provides an elaborate classification of soil types according to several sheet parameters ( most commonly their properties) , Suborder, Subgroup, Family, Great Group Series. Alfisols ( from the soil science term Pedalfer – description aluminum iron) are similar to Ultisols but are less intensively weathered less acidic. Notice the deep A horizon alfisol texture, structure that you can see as you auger, look very carefully for any changes in color that may indicate description a change in description horizon/ subhorizon.
