Classification Of The Soil Drainage Class - 2546 Words

Part 1 Question 1 – LENZ classification LENZ classification- F7.1 Regional average elevation- 520m Climate- Mild temperatures, high solar radiation, slight annual water deficits. Landform- Undulating volcanic plateau. Parent material- Rhyolitic rock Question 2 – Soil types Describe the main soil characteristics for the region including their soil texture, depth, plant available water and drainage. Soil texture- The soil around the Taupo area is a sandy loam which is normally made up of sand along with varying amounts of silt and clay. Soil depth- greater than one meter. Plant available water- the profile of available water for soil depth of 0-100cm or to the root barrier is very high at 162.5 mm. Drainage- The soil drainage class is well drained. Question 3 – Land Evaluation, what it consists of, and what it is capably of a) The land use capability classification (LUC) system has 8 classes, 1-4 is arable land, 5-8 is non arable and 8 is conservation. The higher the class the less versatile the land is. The majority of the land in the Taupo area is class 5-7 which is non arable and unsuitable for cropping but can be productive pastoral hill country, with class 7 having severe limitations. There is also some class 3 which is arable land with some limitations such as restricted crops that can be grown. There is also small amounts of conservation land which is class 8 and has severe to extreme limitations. b) Currently the majority of land in the Taupo area is in plantedShow MoreRelatedConstruction Structure Essay965 Words   |  4 Pagessand or aggregate across the entire site and compact. 5.

However, there are solutions to this problem. Coal ash possesses unique chemical properties that allow for the remediation of other environmental concerns, such as the treatment of soil polluted with heavy metals, the removal of nutrients from wastewat er, and the remediation of acid mine drainage in streams. Coal ash is known to contain a number of different toxic metals, the exact content dependent upon the coal it is formed from. Containing this potential pollution hazard is an expensiveRead MoreAll the Basics There Are to Know about Rivers Essay913 Words   |  4 Pagesbay; however, if it spreads out in several channels, it forms a delta. Classification Not all rivers flow on the earth’s surface; for example, subsurface rivers flow beneath the earth’s surface in caverns and caves. They frequent areas dominated by limestone landforms. Such rivers include subterranean and subglacial streams. Rivers are divided into two broad categories depending on the permanence of their water flow. This class includes permanent and intermittent rivers; the former is available allRead MoreWater Quality Guidelines For Agriculture1331 Words   |  6 PagesNations (FAO) has published the water quality guidelines for agriculture. The agriculture sector consumes about 94 percent of total annual water in Iran as the biggest stakeholder (Alizadeh and Keshavarz, 2005). Given the effects of irrigation water on soil and crops, monitoring and assessment of groundwater quality are very important. Therefore, groundwater quality assessment is one of the most important environmental issues across the world for decision makers. Groundwater, compared to surface waterRead MoreAnalysis Of Watersheds1540 Words   |  7 Pagestime-series datasets (14-35 years). The soil in Sandusky, the northern reaches of Maumee, and Raisin watersheds were clayey soil which formed from beach sediments and glacial till associated with the glacial lakes. The central part of Maumee and the southern part of Sandusky watersheds are characterized by coarse-textured soils formed from glacial deposits. Muskingum watershed is characterized by clayey soils with high slopes and little organic matter content. The soils in the Grand and Cuyahoga watershedsRead MoreEssay on Wetlands1982 Words   |  8 Pagesdifferent groups and individuals, some of the definitions include: â€Å"An area of land that has hydric soil and hydrophytic vegetation, typically flooded for part of the year, and forming a transition zone between aquatic and terrestrial systems (Brady and Weil, 1999).† A wetland is an ecosystem that depends on constant or recurrent, shallow inun dation or saturation at or near the surface of the substrate (soil).

Soils may b e improved through the addition of chemical or cementations additives. These chemical additives range from waste products to manufactured materials and include lime, Class C fly ash, Portland cement, cement kiln dust, RBI Grade 81. These additives can be used with a variety of soils to help improve their soil properties. The results of these additives depends on the soil treated andRead MoreIntroduction Of Industrial Hemp ( Cannabis Sativa L. ) ( No More Than 2 Pages )1411 Words   |  6 Pagesenvironmental conditions.

In these geographic regions where temperature is at such a pronounced extreme, climate would seem to be the leading factor of soil development. It is my goal in this research paper to answer the following question: How do the soils of arctic and alpine areas differ? This idea, taken largely from an
