Rotation and Nitrogen Fertilization Effects on Changes in Soil Carbon and Nitrogen

Entry ID: USDA0098

[ Update this Record ]

Summary

Abstract: The dataset consists of data resulting from an experimental
study involving seven cropping systems (three monoculture, two
2-year, and two 4-year rotations) with three rates of N
fertilizer. Data includes dry matter samples and soil samples
with resulting analyses to determine total C and N content. The
dataset was used to evaluate different treatment and crop
rotation combinations and their ...

Quality This database was developed as part of the Core Database for the State of Kansas. It is suited for county-level and watershed-level analyzes that involve land use and land cover.

See abstract for accuracy assessment results.

The eleven mapped classes are defined as:

Commercial/Industrial (class code 11)- commercial/industrial land consists of areas of ... intensive use with much of the land covered by structures or other hard surfaces. These areas are used predominantly for the manufacture and sale of products and/or services. This category includes the central business districts of cities, towns, and villages; suburban shopping centers and strip developments; educational, governmental, religious, health, correctional and institutional facilities; industrial and commercial complexes; and communications, power, and transportation facilities. The main buildings, secondary structures, and areas supporting the basic use are all included - office buildings, warehouses, driveways, parking lots, landscaped areas, streets, etc. Highways or interstate systems running through the core of urban areas, are also included in this class.

Residential (class code 12)- residential land consists of areas of medium density housing characterized by a more or less even distribution of vegetative cover and houses/garages, to high density housing characterized by multi-unit structures such as apartment complexes. Linear residential developments along transportation routes extending outward from urban areas are included. Rural subdivisions not directly connected to the core of an urbanized area are also included. The main buildings, secondary structures, and immediate surrounding landscape are all included (i.e., house, apartment complexes, streets, garages, driveways, parking areas, lawns, trees, etc.).

Urban-Openland (class code 13)- urban-openland consists of areas with uses such as golf courses, zoos, urban parks, cemeteries, and undeveloped land within an urban setting. Low density rural residential areas may also be included in this category. This category also includes tracts of land that have been zoned residential or commercial, but have yet to be developed.

Urban-Woodland (class code 14)- urban-woodland consists of wooded tracts within a town or city. These wooded tracts maybe associated with golf courses, zoos, urban parks, and other undeveloped land.

Urban-Water (class code 15)- urban-water consists of any open surface water within a town or city. This includes ponds, lakes, sewage settling ponds, etc.

Cropland (class code 20)- cropland includes all areas with actively growing row crop and small grains, as well as harvested lands, fallow land, and large, uniform areas of bare, plowed ground.

Grassland (class code 30)- this category includes all pasture (hayed land), rangeland, and other grasslands having insufficient trees and/or shrubs to be classified as "woodland". It does NOT include conservation reserve program (CRP) land.

Conservation Reserve Program (CRP) Land (class code 31)- this category includes all lands enrolled in the conservation reserve program as determined by the 2005 Common Land Unit (CLU) database.

Woodland (class code 40) - this class includes any wooded areas having a canopy closure of 50% and greater.

Water (class code 50) - all open water bodies, including reservoirs, lakes, ponds, rivers and streams. Ephemeral streams may not be represented.

Other (class code 60)- the "other" class is used to identify land cover land use classes not previously defined. In general, this class is used for exposed bare ground other than cropland. Examples include rock quarries, sand and gravel pits, sandbars, and built-up areas less than 40 acres.
