Correlations of Soil Properties with Index Properties Essay

Soil is the basis for the natural ecosystems and a living thing, it sustains life on Earth and works as a natural recycling facility with nutrients to the plants. However, many people do not know about the good benefits that soil gives to our lives and how humans hurt the conditions of soil with chemicals. Soil is often times mistreated due to the misconception of soil as dirt. Nevertheless, Professor Asmeret Berhe highlighted during the lecture, Soil, that soil is a place of full of life that supports living thing. The living organism depends on the conditions of soil because soil delivers nutrients to plants. For instance, improving the conditions of the soil increases the harvest of crops. Unhealthy soil will not be able to do its job as a natural recycling facility, and not be able to give a good amount of nutrients to plants to abundantly grow. Therefore, conditions of soil are very important in agriculture. Furthermore, having organic soils can conserve the amount of water used for irrigation. Soil is main supply of water to all land and plants because it holds the water for organisms. Organic soil can hold few amounts of water for a long time so it helps farmers to reduce the agricultural water consumption. Soil is very important to out lives than what we imagine and think. The global awareness of soil preservation is less significant to people than other conservation efforts like reducing the amount of plastic used, but soil preservation is very significant to our earth system. Therefore, it is very important for humans to help the Earth healthy sustain life by stop mistreating soil as dirt and treating it as a living thing that holds full of

In agriculture, soil can cause limitations to plant growth through (a) depth, stoniness, texture and structure which together can influence the amount of water which can be held in the profile and the ease with which roots can penetrate and (b) the availability of nutrients (Rowell, 1994). There are four main constituents of soil: mineral matter, organic matter, air and water (Fig. 1.1).

“Drainage patterns, the hilliness of the ground, the range of soils, the nature of the bedrock,

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 soil is mostly known in Wisconsin for the characteristics of being productive, well-drained, and a soil with a

The soil has a thick litter layer, but thin humus layers due to fast decomposition. There is also a rapid leaking, which is the downward movement of the nutrients in solution in the soil. Soil is determined by the climate, vegetation, topographic position and soil age.

A series of experiments was performed on glass beads and natural clean dry sands under the objective of the current work of performing parametric studies. Therefore, new techniques and methods were utilized to predict the gradation of the natural cohesionless silica sands tested in addition to the conventional geotechnical laboratory experiments, which were carried out to predict the mechanical characteristics of such soils. Moreover, ideal laboratory simulations for the SPT were performed under several particular relative densities, loading conditions, and stress-strain controlled boundaries. Additionally, the obtained results from such series of experiments were stored in digital forms for further processing and analyses.

The physical and chemical properties of the soil were analyzed. The soil of the experimental site was lateristic, fairly homogenous with good drainage and moderate acidic. The details of physical and chemical properties are shown in Table 3.2 and the summaries of methods are described in Appendix

Throughout central and southern Mexico, there are high rates of precipitation. Therefore with all the precipitation and solar energy, some of the richest soils are produced in the heart of Mexico. With these accommodations, mostly infertile yellowish soils are produced that are high in iron oxides and also aluminum hydroxide (“Mexico Geography and Climate”). These rich-in base soils are easily crumbled and are continuously farmed annually. But with the continuous farming with these soils, sheet erosion is starting to effect the soil and cause problems within the environment (“Encyclopedia of the Nations”).

Hypothesis The more silt soil contains gives a longer water holding capacity for the soil and the more clay it contains gives a shorter water holding capacity. Procedure I Take separate samples of humus and forest ground soil and place into cups. Using spray bottle filled with water, take a handful of soil into your hand and mist it with water. Squeeze the samples and try to form it into a ball or a ribbon and determine its texture.

soil properties over a larger region may not be so well behaved. In simple words isotropic

If you have made some of the mistakes listed below, don't be too hard on yourself because unless you've completed a fair amount of research on the topic, any one of these oversights are easy to make. Before getting to them, some background information on expansive clay soil is necessary.

There are pedologic cases in which one of the five soil-forming factors established by Jenny (192?) is so prominent and effectual that it outweighs the sum of all of the other factors, resulting in the definition of different soil series almost wholly upon differences in that dominant soil-forming factor. For example, in the Carleton Arboretum, our Soils' class found that the differences in soil series were defined mostly on the basis of parent material. Most groups had a direct correlation between the distribution of soil types and the distribution of parent materials.

Soils with slickensides and wedge-shaped aggregates often have a gilgai, but this is not always the case. Gilgai can be partially or totally erased by cultivation, and it is sometimes possible for other microrelief features. Therefore, gilgai surface topography is not used as a differentiating characteristic for Vertisols. They are known by several other names like Grumosols (Oakes and Thorp 1950), or Tropical Black clays (Kossovich 1912). The classification of Vertisols was revised significantly in the early 1990s to include shrink–swell behavior soil with aquic conditions and with cryic soil temperature regimes, and focus more on soil behavior rather than color. Since the shrink–swell characteristic is not only limited to soils at the order level, several soil can be included in Vertisols.
