Analysis Of The Delpont Soil Series

Found in the Appalachian Region, the Juniata Formation extends from central-southern Pennsylvania to Tennessee (Davies 2010). Though the thickness of the Juniata Formation is far from constant across its lateral extent, it is approximately 2000 feet thick in northern Pennsylvannia and thins towards the southwest (Crowder 1980). Named for the Juniata River running through southern Pennsylvania, this formation consists of sediments from the Taconic Orogeny in the late Ordovician period (Crowder 1980). Figure one displays the characteristic layers of alternating red sandstones and shales, which are divided into three distinct units (Darton

The Texas bottomland hardwood soil is highly fertile due to the nearby water resources. These wetlands are able to control the soil erosion in order to prevent flood damage and maintain water quality. The soil is often a deep brown or brownish-red color.

Contain a distinctive top soil that is humose or peaty and a substratum starting at 40cm in depth which has been altered little (Avery, 1980; Buol, 1997). The soils do not contain a disturbed surface layer, the B horizon is not podzolic, weathered or argillic (Avery, 1980; Buol, 1997) and the soil profile is shallow (Ashman & Puri, 2002).

Extracted soil samples indicate simultaneous reduction of rainfall and occasional erosion. Both soil and sediment features show establishment of marked

The town of Putney is situated in the south eastern corner of Vermont, in the Connecticut River Valley. Although the town occupies just 26.8 square miles, the diversity of its soils is remarkable. The variation of Putney’s soils has led to a wide range of land uses depending on the soil type, and its position on the landscape. By exploring the factors that contributed to the formation of Putney’s soils, and by discussing the characteristics of those soils, this paper will explain the significance of the town’s land use.

North Ridgeville, or Ridgeville County during he earlier parts of history, was once covered by the Late Wisconsin Glacier. In my area here are 6 known soils around the entire county. They are; the Mahoning- Trumbull- Ellsworth association, the Orrville- Lobdell- Chagrin association, the Fitchville- Luray- Sebring association, the Allis- Mitiwanage- Miner association, the Haskins- Jimtown- Oshtemo association, and the Mahoning- Miner association. All of these associations have either near level, or very steep sloping, somewhat poor, to very poor drainage, and we only have 4 horizons found in Lorain County. They are the O, A, B, and C horizons. The state of Ohio is known as the Miamian state soil. They are considered as the most expensive soil around as they have tons of cash crops being farmed, but also because of the drainage being so poor due to dry weather, unpredictable weather, and dry soils. They constantly need to be watered and seeded. The sun just beats down on a lot of the soil, especially my backyard, even with shade present. Ohio is part of 4 other resource regions, which extend from Maine to Alabama, and as far as the eastern part of Nebraska. Much of the soils found near me are left behind the glaciers that carved out the Great Lakes.

Anyways I think mostly what my mom was trying to to do was teach us some values and even though this story is somewhat out of topic the point of the story is the area which I come from is very desirable and I guess always took it for granted until learning more about it now in this class. This region was named for its deep fertile black soils that are most commonly found in the area. At the time of discovery many witnesses that these areas once supported a vast amount of tall grass praries from big blustems, to little bluestems, indian grass, and switch grass; Now, it is mainly used for the production of forage crops (wheat and maize) and cattle ranching. Many describe the soils as dark colored alkaline clays reffered to as black gumbo and gray acidic sandy loams. However the official terminology for the types of soils available in this area fall mostly under alflsols, vertisols, and mollisols. To give a couple of brief characteristics of the types of soils, alfisols have a surface accumulation of clay and about a 35% base of

The types of soils found in the state of Texas vary over a wide range. Research done by the Natural Resources Conservation service indicated that there are approximately over 1300 different types of soils that can be located in the State of Texas. All of these soil types each play a different role in how it affects the foundation of structures. However, this wide range of soil types, has been shrunk down to fit into nine groups of Taxonomy to help make it easier for identification and research (Vepraskas et al., 26). In this essay, I shall discuss the different types of soils that can be located in Texas according to their respective taxonomic group.

The location of the Northeast Transect Line is shown in the Figure 3. The profile information is shown in Figure 4. According to Figure 4, the length of the Northeast Transect Line is 668 feet. Each plot is 66 feet long or 20 meters long; however, the last plot, plot 10, is longer than the rest at 74 feet. The steepest slope in the Northeast Transect occurs from Plot 1 to Plot 4; the elevation decreases approximately from 1330 feet to 1280 feet. After Plot 5, the slope becomes much more subtle (roughly 1270 feet). The species composition is listed in Table 1. Little Bluestem, Yellow Indiangrass, Switchgrass, and Big Bluestem appear in every plot in the transect line. Ragweed and Heath Aster appear in 9 plots. Prairie Cone Flower, White Sage, Roundhead Lespedeza, St. John's Wort, Hoary Verbena, Leadplant, Prairie Rose, Roughleaf Dogwood, Kansas Gayfeather, Western Silky Aster, Boneset, Pitcher Sage, and Smooth Sumac appear in no more than 3 plots.

In North America, sodic soils are mostly found in the northern Great Plains of the United States. Sodic soils develops on glacial deposits and till of saline shales (Heck and Mermut, 1992). The presence of a fluctuating water table, landscape position, topography, parent material permeability elevate the sodicity on glacial deposits (Wilding et al., 1963; Lewis and drew, 1973; Munn and Boehm, 1983; Seelig et al., 190; Richardson et al, 1992). The total area of North Dakota in the United States is about 18.4 million hectares and of these 1.9 million hectare area are considered as sodic and distributed across several parent materials (Web Soil Survey, 2013). Sodic soils are characterized by high sodium (Na) concentration in cation exchange complex. Which is about greater than 15% and defined as the soil with high sodium as compared to calcium and magnesium (Salcon, 1997, Soil Taxonomy, 1999). Sodic soil is one of the problematic soils which weaken the soil structure of the soils (Rengasamy and walters, 1994). So it is important to study these soil in detail by physical, chemical and micro morphological method and in relation to environment.

Little Bluestem-Dry Mesic also occurs mostly in the Northern half of the park, primarily on the side slopes of cuestas, seen in Figure #. The elevation of Little Bluestem-Dry Mesic varies significantly. It reaches from almost as low as 1290 feet up to 1335 feet (Keane, 2015). Due to this variance in elevation, there is slightly more of a difference in soil qualities from higher to lower. The primary soil type present is Benfield with some Dwight-Irwin Complex occurring in the lowest elevations (USDA, 2015). The Benfield soil in this ecosystem is still relatively shallow with the A Horizon reaching a depth of 10 feet and the next horizon, Bt1 reaching only another 9 feet down. The parent material for Benfield is pedisediment over residuum weathered from shale, allowing for smaller clay particles to form.

Most of the mountainous landscapes of British Columbia’s soil are coated with loose soil, underlying weathered bedrock. The soils found lack cohesion when in high water content, have low bulk density and are rocky. Making the surface mostly unconsolidated and unstable when saturated and made up of
