List of U.S. state soils

Last updated

This is a list of U.S. state soils. A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds. Also, representative soils have been selected for Puerto Rico and the U.S. Virgin Islands. [1]

The National Cooperative Soil Survey Program (NCSS) in the United States is a nationwide partnership of federal, regional, state, and local agencies and institutions. This partnership works together to cooperatively investigate, inventory, document, classify, and interpret soils and to disseminate, publish, and promote the use of information about the soils of the United States and its trust territories. The activities of the NCSS are carried out on national, regional, and state levels.

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. They are common soils on semiarid rangeland with sagebrush-grassland plant communities. Orovada soils are arable, able to be cultivated, when irrigated and are considered prime farmland. Alfalfa for hay and seed, winter wheat, barley, and grasses for hay and pasture are the principal crops grown on these soils.

Klamath Basin

The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.

The Alabama Department of Conservation and Natural Resources (ADCNR) is the state agency responsible for the conservation and management of Alabama's natural resources including state parks, state lands, wildlife and aquatic resources. ADCNR also issues hunting and fishing licenses for the state. The department promotes wise stewardship and enjoyment of the state's natural resources through five divisions: Marine Police, Marine Resources, State Lands, State Parks and Wildlife and Freshwater Fisheries. Supporting those divisions are seven support sections: Accounting, Diversity and Recruiting, Engineering, Information and Education, Information Technology, Legal, and Personnel and Payroll.

Buffer strip

A buffer strip is an area of land maintained in permanent vegetation that helps to control air, soil, and water quality, along with other environmental problems, dealing primarily on land that is used in agriculture. Buffer strips trap sediment, and enhance filtration of nutrients and pesticides by slowing down runoff that could enter the local surface waters. The root systems of the planted vegetation in these buffers hold soil particles together which alleviate the soil of wind erosion and stabilize stream banks providing protection against substantial erosion and landslides. Farmers can also use buffer strips to square up existing crop fields to provide safety for equipment while also farming more efficiently.

Conservation Effects Assessment Project United States government project

The Conservation Effects Assessment Project (CEAP) was established in 2002 to quantify the environmental impact of the United States Department of Agriculture's (USDA) conservation program. The project focuses on how watersheds are affected. CEAP monitored 14 benchmark watershed sites. The CEAP's vision is to enhance "natural resources and healthier ecosystems through improved conservation effectiveness and better management of agricultural landscapes. The goal is "to improve efficacy of conservations practices and programs by quantifying conservation effects and providing the science and education base needed to enrich conservation planning, implementation, management decisions, and policy."

The Conservation Security Program (CSP) was a voluntary conservation program in the United States that supported stewardship of private agricultural lands by providing payments and technical assistance for maintaining and enhancing natural resources. The program promoted the conservation and improvement of soil, water, air, energy, plant and animal life, and other conservation purposes. Congress established the CSP under the Farm Security and Rural Investment Act of 2002 (FSRIA), which amended the Food Security Act of 1985. The program was administered by the Natural Resources Conservation Service (NRCS), an agency of the United States Department of Agriculture (USDA).

Jory (soil) soil type

The Jory series consists of very deep, well-drained soils that formed in colluvium derived from basic igneous rock. These soils are in the foothills surrounding the Willamette Valley of the United States. They have been mapped on more than 300,000 acres (1,200 km2) in western Oregon. They are named after Jory Hill, Marion County, Oregon, which itself is named for the Jory family, who settled in the area in 1852, after traveling along the Oregon Trail.

Economy of Oregon

The economy of the U.S. state of Oregon is made up of a number of sectors. During the 1990s and 2000s, Oregon has attempted to transition its economy from one based on natural resources to one based on a mix of manufacturing, services, and high technology.
