1 <br />1 <br /> <br />s <br />t MESh GRAVELi:d CLr.Y LOA•:, 5 to 10 percent slopes, C'_ass IVe Land (IBS) <br />' This soil occurs principally on terrace slopes or escarpments. <br />Except for its greater slope, this soil closely resembles Mesa gravelly <br />clay loam, 2 tc 5 percent slopes. Its workability is someu::et less <br />favorable, houe•rer, as it is m,re gravelly and cobtly. Har:ful con- <br />' centrations of salts are negligible. <br />The soil is not so productive as the Mesa clay loam s, because the <br />' excess gravel, cobbles, and stones in the surface soil and throughout <br />the profile reduce the moisture-holding capacity. Painstaking ap- <br />' placation of irrigation water, with special care ir. regulating rate of <br />flew, is regLired to prevent unnecessa__^y loss of surface soil. <br />' Soil limitations are classified as severe for sewage lage:r.s (rapid <br />peraeability). <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br />
