Soils have been classified according to a system developed by soil scientists and the U.S. Soil Conservation Service. Using this classification system of soil orders, pick two locations on Earth, one in your current area and another area, and describe the order and the conditions that define it. (See Figure 4.12 in the textbook.)…

The War of 1812 was a war that lasted for two years that helped the United States to firmly and officially establish its independence. After finishing with the concern of France, England turned its attention over to the United States. At first, the United States did not want to resort to war and fighting (Doc. B) but rather sort out their issues economically--because England had seized all ships that did not stop in the British port before heading to their other European destinations, Congress passed the Embargo Act and then the Non-Intercourse Act, allowing trade with all nations except France and England. Then, England refused to allow this trade to occur, so America had to resort to war. The Northeastern Federalists were not in favor of war, but the Republicans ultimately won the majority vote in Congress to declare war--the War of 1812 (Doc. G). During this war, America was very concerned with gaining control over land in this country as well as in Canada, but at the same time Americans needed to defend themselves against their strong British enemies. Either way, America had to abandon its position of neutrality (Doc. C).…
The soil isn’t a true soilbecause of the Permafrost developed, the freeze-thaw activity, a thin active layer, and solidification. This soil is moist and thin over the permafrost; furthermore the soil has low nutrients and is also slightly acidic. The Permafrost serves as a barrier to keep animals from…
What is your definition of soil? What is soil composed of? Why is soil important to the environment?…
The purpose of this lab was to be able to understand the importance of differing soil and to be able to determine the type of soil that was given. This would also help in understanding each type of soil and the nutrients and water that it is able to hold.…
A soil that has a high base saturation (%BS), pH of 7, a 1:1 clay material, and high Organic Matter (OM). All of these provide a larger number of exchangeable cations available for the soil. Any soil differentiating from these will provide only a lower number exchangeable…
The first layer (O) we observed is the top layer, a layer of organic soil. It is made up of humus and leaf sediment. Below that (A) comes the topsoil. This is where seeds sprout and other plants roots grow. This layer is also made up of humus, but here are other mineral particles as well. Next is the eluviation layer (E). This layer contains mostly sand and silt. It is the eluviation layer because of the process that takes place here where minerals are…
* Soil Texture refers to the relative proportions of different sized inorganic mineral particles of sand, silt, and clay.…
The type of weathered material which composes the majority of the soil (not including any biota or mixing agents) has a profound relationship with the composition with the soil.…
Top soil is the top layer of the earths surface where all the exposed nutrients are found. This occurs when the rabbit are eating grass then they take fragments of dirt with them that can cause a long term affect as now the layer will have to take around 100 years to rejuvenate.…

In a changing climate, horticulturalists and landscape professionals are looking for ways to ensure the establishment and healthy growth of plants, whilst minimizing the use of both water and chemical fertilizers. The demands on potable water have never been greater than they are today and with rising populations demands are likely to increase further. Many soils…
