SummaryNo mature soils were observed in the area round Kennan, much of which was occupied by lithosols and regosols. The profiles of immature soils on the fine outwash alluvium occupying some of the broad valleys suggested that the zonal Great Soil Group would be a Reddish Desert Soil. Phosphate and potassium levels of cultivated soils on the fine alluvium are adequate or good; the total nitrogen content is low, though higher on cultivated than on uncultivated soils.
IntroductoryOVER much of the central Persian plateau the general relation between soils of the area it is basin, mutatis catena of mountains-plain-mountains of the Kerman basin may be observed in most parts of the parallel chains of inland basins running from Ardistan to Kerman, and Isfahan to Sirjan (Saidabad). The halfcatena mountains-plain-desert occurs round most of the west, north, and east borders of the plateau, across the boundary between the surrounding mountains and the central desert.
Landscape and GeologyFor the purpose of this study the Kerman basin was arbitrarily defined to include parts of two broad valleys, converging on the town and lain of Kerman, and the containing mountains at their junction and &hest point (5,000-6,000 ft. above sea level) (see map).Many of the crests of the surrounding mountains 10,000-13,000 ft.)

The limestones, and the grits or shales when capped by limestone, weather to roduce a typical arid landscape in fans. Where not protected by overlying limestones the shales and grits weather to form a broken landscape of low rounded hills, as in the rough foothills of the Kuh-i-Jupar. Further isolated outcrops of Cretaceous limestone form steep hills on the plain, risin 500 to 2,000 ft. above conglomerate and pebbly sandstone form the outer edge of the Kuh-ihuman settlement is fairly uniform, so of published descriptions of the legitimate to generalize from the KermanI e plateau in general.
