CORDOVA'SERIES <br /> The-Cordo��a series consists of ver}�deep,poorly drained.soils that:formed mostly in loamy calcareous.g(acial till on <br /> ground moraines and cill piains.The upper part of the profile.in some of these soils formed in modified glacial tili: <br /> These soils have moderately slow permeability.Their slopes are less than,2 percent.N1ean annual precipitation is <br /> aboue28 inches.Mean annual temperature is about 48 degrees F: <br /> TA�ONOMIC CLASS; Fine-loamy, rnixed, superactive, mesic Typic.Argiaquolls <br /> • TYPICAI.P�DON: Cordava clay:laam with a plane slope of 1 percent in:a cultivated f eld. <br /> � (Colors are for moist soil unless othervvise stated.) <br /> Ap—O to 10 inches;black(N 2/0) clay loam, very dark gray (1:OYR 3/T) dry; moderate medium <br /> subangular blocky strueture;friable; about 1 percent gravel; neutral; abrupt wavy boundary. <br /> A--10:to 18 inches;bTaek�(N'2/0) clay loam,bery dark gray(�lOYR 3/1) dry;,moderate medium, <br /> subangular blocky structure;friable; about 1 percent gravel; neutraT;clear wavy boundary. <br /> (Combined A hor.izon is 8'to 20 inehes,) <br /> Btg'1-=1$to 3.0 inches;olive gray(SY 4/2)clay loam;few fine prominent dark yellowish brown <br /> � (1.OYR 4/6).Fe<concentrations;modetate medium angulaz blocky structure parting to moderate .. <br /> �'ine angular�bloc�y; friable;common very dark gray(5Y 3/1) clay films on faces of peds and in <br /> pores,;about.3 percent gravel; neutral;clear wavy boundary. � <br /> Btg2-30 to 38.inches; olive gray(SY 5/2) clay loam; common fine prominent dark yellowish <br /> brown(lOYR 4/6j Fe concentrations; weak medium subanb lar blocky sfructure;friable;few <br /> distiinct uery dark b ay(SY 3/1)clay films on faces of peds and in pores; abaut 3 percent gravel; <br /> neutra.i; a6rupt wavy boundary.
