Orovada series
soil is the official state soil of Nevada. The soil series has an extent of 367,853 acres (148,865 ha), primarily in northern and central Nevada, and extending into southern Idaho and Oregon.[1] They are common soils on semiarid
rangeland with
sagebrush-
grasslandplant communities. Orovada soils are
arable, able to be cultivated, when irrigated and are considered prime
farmland. [citation needed]Alfalfa for
hay and seed,
winter wheat,
barley, and
grasses for hay and
pasture are the principal crops grown on these soils.
