Soil Analysis
Introduction- The purpose of this investigation was to identify the texture of the soil we collected, while learning the different methods used to determine soil texture. I hypothesized the soil we collected from the North side of the school would be Clay Loam. In the Soil Introduction Power Point we learned about the pedosphere. We discovered that soil houses both organic (materials containing carbon compounds) and inorganic matter (materials like minerals: phosphates and nitrates). Also, we found the components that make up the ideal soil. (Diagram A below). It must have pore space for the exchange of gases and water movement to keep it healthy. Then we talked about the five factors that make soil, or how it forms. A

The last part of the Power Point was the layers soil forms as it develops including duff, topsoil, subsoil, and bedrock. Duff is top layer of organic matter, which isn’t always there because it could have been mowed or washed away. Topsoil is the second layer and the most fertile layer with a lot of nutrients where most of the plant’s roots are. The third layer, also called subsoil, is less nutrient rich and has less organic material; it is possible for some roots to reach this layer. The final layer is bedrock, a solid layer of rock beneath some soils. (Note: Some soils not all soils; these layers can vary at different locations) During the Soil Water Absorption Power Point on the other hand, we learned how a soil’s texture could control the amount and how quickly water can seep into the layers of soil (the duff, topsoil, subsoil, and bedrock). A soil’s capability to collect and store water is vital to the other parts of the ecosystem like the plants growing there and the topography. An example of that could be erosion. The texture of the soil also affects the other parts of the soil as well, such as the pore space. Poor space is the bare space between the particles of soil that can be infiltrated by the air and water. If there is a lot of poor space then the soil can absorb a lot of water but too much poor space is not a good thing. If there is too much, water will carry through so quickly the plants can’t exploit it. Similarly,
Election of 1828 is what started it all. Andrew Jackson and John Quincy Adams was running for President, and Andrew Jackson won by an overwhelming majority. Jackson established the Spoil System. The Spoil System awarded Jackson’s friends and supporters public offices. During the 1830’s, abolitionist began to rise, and people began to revolt, for example, William Garrison wrote the “Liberator”, and Nat Turner killed his master and 60 more people. Money was a huge issue because tariffs were raised, and Jackson destroyed the National Banks, which caused the Panic of 1837. The big issue during the 1850’s was the decision if slavery should expand into the new territory that America had gained from the Mexican War. The documents support the explanation
Soil, which is the layer of earth on the top where plants and vegetation grow, contains a pH balance, everything does. The pH, acidity, or alkalinity balance of each type of soil that is being observed can affect the plants, because it determines how many nutrients are being deposited to them. It

#2. The small “lens” of soil left-over from the glaciers can survive after the Ice Age because the lens becomes larger and deeper. So, the soil building thickens the soil with was strong enough to support biodiversity.
These are soils consisting predominantly of unaltered mineral material that have no surface/sub-surface horizon attributed to soil forming processes (unless buried under a 730cm thick deposit from the Holocene) (Avery, 1980;). These soils do not normally have continuous vegetation cover (Avery, 1980). They occur in very recently formed soil and may have a superficial organic or organo-mineral layer less than 5cm thick. Sometimes they have a buried horizon below 30cm of depth. (Thompson, 2007; Jarvis, 1984).
Vast numbers and kinds of organisms, mainly microorganisms, inhabit soil and depend on it for shelter, food, and water. Plants anchor themselves in soil, and from it they receive essential minerals and water. Terrestrial plants could not survive without soil, and because we depend on plants for our food, humans could not exist without soil either (Wiley, 2013).
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 texture of the soil is very dry. The soils are porous and can hardly hold any water. Moreover, it is considerably impermeable to any moisture. The Aridisols does not support plant life, but instead, it promotes minerals (Allen et al., 19). Their location is mainly in the desert areas. It is found in the far western part of the state of Texas. However, some little vegetation can grow on its topsoil. There are several minerals located in the aridisols namely gypsum, sodium, calcium and carbonate (Ettema et al., 45). Also, the soil provides the perfect texture for building the foundation of a structure.
Loose soil from digging animals is easier for plants to grow in compared to the hard compacted soil found where there are no digging animals
The soil is mostly known in Wisconsin for the characteristics of being productive, well-drained, and a soil with a
Did you know that soil makes up the outermost layer of our planet? Texas is home to more than 1,000 different kinds of soil which are classified into 9 soil orders. Out of the 1,000 types of soil only 6% are able to sustain crop life. In South Texas the most common type of soil is sandy loom soil which is classified as a molliols. Sandy loom soil
Smithville’s Joel Shoup said there are a lot of different soil types, and the kind of soil can change over a short distance. “You can go 20 feet and find differences,” he said.
Firstly, Plant roots break up rocks into smaller chunks. One example of this is on the Canadian Shield, where trees break up rocks as they grow. On the Canadian Shield, trees are growing on rocks, and since they have nowhere to go but into the rock, they end up breaking the parent rock up as they grow. Secondly, plant roots hold soil in place to prevent it from eroding. Along most shorelines in lakes and rivers, plants hold the shoreline together. In urban areas where there are not any plants, people either have to put mesh to hold the grass together, or just replace it with concrete. Plants are important to keeping the soil together. In places without plants along the coastline, the soil erodes away because of the water. Lastly, plants decompose into humus at the end of their lifetime, which fertilizes the soil. An example of this is in the west coast climate region, there are a lot of plants. They grow everywhere and they grow quickly because of the fertile soil, the large amounts of rain, and the mild temperatures. The plants grow, and then after they die, they turn into humus, and fertilize the soil. Then, the cycle starts again. This fast cycle makes the soil very fertile. Vegetation is very important in fertilizing and maintaining the
Erosion removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. Thus it affects the productivity of plants. The remaining, the subsoil, tends to be less fertile, less absorbent and less able to retain pesticides, fertilizers, and other plant nutrients. There are over 17,000 soil types recognized worldwide. They vary widely in structure, erodibility, fertility, and ability to produce crops. A generalized soil profile for a humid, temperate climate is showed. When the natural vegetation is cleared for agriculture, soils become exposed to erosion and loss of soil fertility. The removal of the above-ground natural
The three groups of soils were then divided into seven soil reference groups according to the MALSIS database. There are the
