21 - Dacono clay loam, 0 to 1 percent slopes. This is a deep, well drained soil on
terraces at elevations of 4,550 to 4,970 feet. It formed in mixed alluvium. Included in
mapping are small, long and narrow areas of sand and gravel deposits and some small leveled
areas.
Typically the surface layer of this Dacono soil is grayish brown clay loam about 12
inches thick. The subsoil is grayish brown clay loam about 15 inches thick. The sub-stratum
is very gravelly sand.
Permeability is moderately slow. Available water capacity is moderate. The effective
rooting depth is 20 to 40 inches. Surface runoff is slow, and the erosion hazard is low.
This soil is used almost entirely for irrigated crops. It is suited to all crops commonly grown
in the area, including corn, sugar beets, beans, alfalfa, small grain, potatoes, and onions. An
example of a suitable cropping system is 3 to 4 years of alfalfa followed by corn, corn for
silage, sugar beets, small grain, or beans. Generally, such characteristics as a high clay
content or a rapidly permeable substratum slightly restrict some crops.
All methods of irrigation are suitable, but furrow irrigation is the most common.
Proper irrigation water management is essential. Barnyard manure and commercial fertilizer
are needed for top yields.
Windbreaks and environmental plantings of trees and shrubs commonly grown in the
area are generally well suited to this soil. Cultivation to control competing vegetation should
be continued for as many years as possible following planting. Trees that are best suited and
have good survival are Rocky Mountain juniper, eastern redcedar, ponderosa pine., Siberian
elm, Russian-olive, and hackberry. The shrubs best suited are skinkbush sumac, lilac,
Siberian peashrub, and American plum.
Openland wildlife, such as pheasant, mourning dove, and cottontail are best suited to
this soil. Wildlife habitat development, including tree and shrub plantings and grass plantings
to serve as nesting areas, should be successful without irrigation during most years. Under
irrigation, good wildlife habitat can be established, benefiting, many kinds of openland
wildlife
This soil has only fair potential for urban and recreational development. Above the
sand and gravel substratum the soil has moderate to high shrink swell, low strength, and
moderately slow permeability. These features create problems in dwelling and road
construction. Excessive permeability in the substratum can cause contamination of the ground
water supply from septic tank leach fields. Sewage lagoons need to be lined. Capability
subclass Hs irrigated.
