MLRA notes

Major Land Resource Area (MLRA): 134X–Southern Mississippi Valley Loess

MLRA 134, Southern Mississippi Valley Loess, is in Mississippi (39 percent), Tennessee (23 percent), Louisiana (15 percent), Arkansas (11 percent), Kentucky (9 percent), Missouri (2 percent), and Illinois (1 percent). It makes up about 26,520 square miles (68,715 square kilometers). The northern part of the area includes Paducah and Murray, Kentucky; Paragould, Jonesboro, and Forrest City, Arkansas; and Memphis, Dyersburg, Bartlett, and Germantown, Tennessee. The southern part includes Yazoo City, Clinton, and Jackson, Mississippi, and Baton Rouge, Opelousas, Lafayette, and New Iberia, Louisiana. This portion is the central western part of the MLRA in Louisiana and Arkansas. It is in the Macon Ridge Section of the EPA Ecoregions in sub-section 73j. The dissected plains in this MLRA have a loess mantle that is thick at the valley wall and thins rapidly as distance from the valley wall increases. This portion of the MLRA is distinct from other portions of the MLRA because of the influences of the Mississippi River and it series of entrenchments and adjacent old channels of the Arkansas River, such channels as Bayou Bartholomew, Bayou Bonnne Idee, Boeuf River, and segments of the Ouachita River. The Macon Ridge has been inhabited prior to European Settlement, Poverty Point is located on the east central portion of the Macon Ridge and has earthworks dating back to 1700-1100 BC.

Ecological site concept

The site is nearly level thin loess, less than 4ft thick, potentially reworked loess by water. The site is poorly drained, rarely to occasionally flooded. Found on broad flats, drainage ways and depressional areas on terraces of the Macon Ridge likely overlaying clayey braided stream materials. Chemical properties of the soil are potentially acid while the subsoil is potentially high in Na (Sodium). Community species would have a range of wetness tolerance from Willow oak which is commonly found up to less abundant Water oak in the driest areas of the site.

Physiographic features

Macon Ridge in extreme northeastern Louisiana and southeastern Arkansas is a 135-mile long prominent ridge that lies between the Boeuf and Tensas Basins (Saucier, 1994). Macon Ridge is a terrace that features level to gently undulating topography with steep scarps of uplands, floodplains, depressions, and drainageways. The entire area is located within the Mississippi Alluvial Valley section of the Coastal Plain Province of the Atlantic Plain. It reaches a maximum width of about 25 miles in northeastern Louisiana about 30 miles north of Sicily Island (Saucier, 1994). Elevation ranges from 50 to 150 feet (15 to 46 m). The ridge is consistently higher on its eastern side where elevations are 20 to 30 feet higher than in the adjacent Tensas Basin (floodplain). It is bounded on the eastern edge by Bayou Macon. On the western side, bounded by the Boeuf River, elevations of the ridge are approximately the same as those in the Boeuf Basin, and it is sometimes difficult to distinguish the two at the surface (Saucier, 1994). Both Bayou Macon and Boeuf River are underfit streams occupying ancient Arkansas River meanders. The entire Macon Ridge is underlain by Pleistocene-aged loamy and clayey braided stream alluvium from the “old” Arkansas River. Macon Ridge consists almost entirely of Early Wisconsin age glacial outwash and is a continuation of the valley train in the Western Lowlands (Saucier, 1994). The area mantled by loess on the eastern edge of the terrace rises 10 to 30 feet above the floodplains. The loess thins toward the west, and elevation decreases. The loess in the western part of Macon Ridge contains small mixtures of the older underlying braided-stream terrace alluvium, and in even lower elevations, the loess contains mixtures of recent clayey alluvium or is buried completely beneath recent alluvium (T. E. Allen, USDA-NRCS Richland Parish Soil Survey Report, 1993).

This PES occurs on clayey and silty broad flats and depressional areas adjacent to drainageways on the Macon Ridge in Arkansas and Louisiana. Slopes are level (0 to 1%). The site occurs on terraces, floodplains, depressions and swales of the loess-mantled Macon Ridge braided-stream terrace. These soils are coarse-silty, fine-silty and fine to a depth of 80 inches or more.

Climatic features

The climate of North East Louisiana and South East Arkansas is warm and humid with a monthly precipitation that is well distributed throughout the year. The monthly precipitation mean is between 2.9 and 5.3 inches, with the lowest rainfall occurring from June through November. The following climatic data are averages from the three weather stations listed below. Temperature and precipitation may vary considerably from that listed for each month. Site specific weather data should be used for land management decisions. For site specific weather conditions, obtain data from a weather station close to the site.

Influencing water features

This site is influenced by both surface and sub-surface hydrology. Standing water can be found in the winter months and soils may be saturated into early spring. Wetness is a dominate driver of this system and in Alternative States it will be a limiting factor. Flooding and ponding are not generally noted in the soils of this site, however the site is generally found in the lower portions of the landscape so it will receive surface flows from adjacent areas which will influence soil saturation.

Soil features

Forestdale, silty clay loam, Calhoun, Gilbert, Henry

Soils are poorly drained, Typic Endoaqualfs (Forestdale), Typic Glossaqualfs (Calhoun and Gilbert), and Typic Fragiaqualfs (Henry). These soils formed from mixed clayey, and loamy alluvium, and loess sediments of late Pleistocene Age. Slopes range from 0 to 1 percent. These very deep, slowly and very slowly permeable soils are found in broad flats and narrow depressional areas adjacent to drainageways in the terrace uplands. These soils are considered hydric and the water table is at or within 1.5 feet of the surface during winter and spring months in normal years. These soils are subject to rare flooding for brief duration.

Ecological dynamics

The pre settlement plant community of this site would have been dominated by bottomland hardwood species. Within this site there will be a gradient of wetness from Rare to No flooding and brief duration. The wetness variations will dictate the species that are present and the composition of them within an area.

Due to wetness, rooting depths of some species will be limited and due to this there is a potential for some trees to be uprooted by climatic events, such as strong winds or floods. With these events, openings in the canopy can occur which will set back succession and allow herbaceous and woody shrub species to colonize, these low stature communities are generally short lived and the upper canopy will close as tall growing trees mature. There is generally an age gradient within a forest stand from the herbaceous openings to mature bottomland hardwoods.

This site has been altered by human activity and is utilized for multiple production systems such as Aquaculture, Cropland, Pasture and Tree Farms, for all of these alternative states wetness is a limitation for this site for productivity and management activities. Within the alternative uses of the site the transitions will be very similar and require the input of resources such as installation of infrastructure needs and establishment of the desired species.

Pasture

Pasture or Grassland This phase is characterized by a monoculture of or mixture of Forage species planted or allowed to establish from naturalized species managed for forage production or as herbaceous ground cover. This Site fits into multiple Pasture & Hayland Groups: 1A, 2D, 8A, 8F, 8G or 8I • 1-Bottomland, deep, fine-textured soil • 2-Bottomland, deep, medium-textured soil • 8-Upland, deep, medium-textured soil • A – soils having few limitations for the growth of the commonly grown plants except for slope • D – organic soils – restrictions due to wetness and traffic ability • F – soils with restricted rooting depth because of fragipans, claypans and other slowly permeable layers which restrict growth and adaptation • G – unfavorable chemical properties such as excessive salts, high exchangeable sodium, unfavorable soil reaction or toxic materials From these bullet descriptions of the Groups this site would generally be described as a Deep, fine to Medium textured soil on Uplands and alluvial bottoms. It has a range of few to wetness limitations, root restricting layers and soil chemistry. Soils descriptions of some of the soils note a presence of Aluminum (Al) in the soil profile and others a potential for a Fragipan or fragic layer. 1A - Mainly poorly drained and somewhat poorly drained, clayey bottom land soils. Most soils have a clayey surface layer. Some soils have a thin loamy overwash on the surface. Natural fertility is mostly medium to high. The soils are nonflooded or rarely flooded. 0-8% slopes. Most slopes are 0-3%. Only a few soils occur on 3-8% slopes. 2D - Bottom land soils that mainly have loamy surface layers and loamy subsoils. Mainly well or moderately well drained, acid, bottom land soils of low or medium natural fertility. Includes some somewhat poorly drained soils and some soils that are subject to rare or occasional overflow for brief periods. 0-5% slopes. Only a few soils occur on 3 to 5% slopes. 8A - Silty upland soils that formed in loess or loess-like materials. Well drained and moderately well drained, acid soils that are silty in the upper 20 inches. The subsoil is silty or clayey. Fertility is low or medium. 0-12% slopes. There are only a few soils in the 8-12% range. 8F - Silty upland and stream terrace soils that formed in loss or silty alluvium. The soils have a silty surface layer and a silty or clayey subsoil. Somewhat poorly drained, acid soils of low or medium natural fertility. 0-5% slopes. 8G - Upland and stream terrace soils mostly with silty surface layers and silty or clayey subsoils. Mainly poorly drained, acid soils of low natural fertility. 0-3% slopes. Most slopes are 0-1%. 8H - Upland and terrace soils with mainly silty surface layers and silty subsoils. Poorly drained to moderately well drained soils of low or medium natural fertility. The soils are alkaline within 20 inches of the surface. 0-1% slopes. 8I - Upland and terrace soils with silty surface layers and subsoils. Poorly drained and somewhat poorly drained, droughty, alkaline soils that have a concentration of sodium in the subsoil. Natural fertility is low or medium. 0-3% slopes. Most slopes are 0-1%. All soils need nitrogen fertilization for production when grasses are grown alone. It is not practical to apply high rates of fertilizer due to the wetness limitation potential of the site which normally occurs from December through June. To prevent extreme acidity in the subsoil when high rates of acidifying nitrogen is used, the surface soil should not be allowed to become more acid than 5.0 pH and lime should be applied at more frequent intervals. Adapted Grasses and Legumes Bahia and common bermuda are adapted. The adapted cool season legumes are white clover, winter peas, and vetch. White clover requires a higher level of calcium and phosphorus than peas or vetch. Tall fescue does well on these soils if good management is applied. Without fertilization, these soils will normally support a cover of little bluestem, slender bluestem, threeawns, broomsedge and carpetgrass.

Rangeland health reference sheet

Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant community cannot be used to identify the ecological site.
