All of the pages listed above provide bolded words that are good terms to know when studying the topic. Another great feature is that they provide other good resources about soil. One fault in this website is on the “Soil” page. The paragraphs are repetitive. There are no bibliography or author credentials. It is easy to navigate though. This is a good website because it was recently updated on April 18, 2008.

"SOILCLIM" (2017)

https://www.biology.lu.se/research/research-groups/soil-ecology/research-projects/soilclim

This website strived to provide farmers and policy makers with adequate research on how Europe’s soil ecology was doing with recent agricultural intensification. The downside of this website is it requires the user to dive deeper into the tabs to find direct answers and research, while not giving it in a condensed “General Soil Ecology” article. The research is quite interesting in it provides real life images of what the groups are doing. “To address the effects of reduced rainfall, SOILCLIM will establish roof experiments with roofs that partially exclude rain and thus simulate drought conditions.” This experiment was cool in that it simulated drought effects on certain patches of grass in a field. The website is neatly structured and easy to find.

“Soil Science Education.” (2005)

http://soil.gsfc.nasa.gov/

This site is very student oriented, if a little juvenile.  There are many interactive areas of the site, including activities to help learn about certain topics.  There are many interesting graphics and visually it is very interesting.  The site answers such questions as “How Much Soil Is There?” creatively, and the writing is very easy to understand.  However, sometimes the site is hard to navigate and can go off-topic with in the article you may be reading.  This is a very good site for getting very basic information on soil, and the site’s visuals make the webpage much more interesting.

“Soil Science: an interdisciplinary approach to soil research.” (2002)

http://www.soilsci.com/

        This site contains abstracts of research papers, and some full research papers, from the journal soil science.  The papers cover many different, but specific topics.  Fortunately, there is a search option provided and it works very well.

The papers cover all topics in soil science, however each pertains to a very small part of the field and I would not recommend using this site for background information.  Also, most of the papers are not accessible for free.  The papers themselves have good bibliographies; unfortunately, with out being a subscriber one can only see abstracts of most of the papers.  The site also has few pictures.  On the other hand, this site has good author credibility; most of the authors hold Ph.D.s.  The site also has good contact information and good links.  Finally, this site is very easy to navigate.

"Soil Studies." (2007)

http://geographyfieldwork.com/FieldworkPackagesSoils.htm.

This site is an informative report about the field studies which are conducted in Europe. These soil studies are being conducted in Garraf National Park. The scientists are comparing and contrasting different processes to understand more about this environment. Some of these processes include comparing a variety of different soil; comparing the depth of the soil to the gradient; and how human action is affecting the quality of the soil. This website would be helpful to people who are learning how to conduct a soil study. They are trying to see if the process of leaching and oxidation effects the soil. There is also more information about the soil studies if you click “more” for the next page.  

“Soil Survey Information for New England.” (2005)

         The soils study took pace in Malaysia to see if tin mining affected the chemistry of the soil and water. They give explicit descriptions of where soil samples were taken and the climate surrounding the area. The results of this study are pretty fascinating. The study was directed by professors at the University of Malaysia in the department of chemistry and geology. The website includes many visuals, many that show where samples were taken. This document is very specific because it pertains to a specific location in the world. It would take a long time to read considering it is 21 pages, but it becomes very specific and in depth. The navigation is fairly easy. The list of references is extensive and gives the reader some more links to follow if they are still interesting in the topic of soil studies. Data tables are located at the end of the document, if a reader would like to see the exact results of this soil study.

https://www.soils.org/discover-soils/story/tale-two-soil-cities

This article talks about connections between aggregates, which are clusters of soil particles, pores in soil and bacteria and microorganisms that live in the pores.  It explains that the pore size of the soil aggregates can affect the types of microorganisms that live in a specific place.  This is a very informative and easy to read article with a few pictures and captions explaining some of the different ideas which are discussed.  It was recently published using the Soil Science Society of America Journal as its main reference.

“The Topic: Soil.” (2002)

 http://www.eduscapes.com/42explore/dirt.htm

        This site gives the basics about soil, and by basics I mean really basic as in: “Soil is a mixture of mineral and organic materials plus air and water. The contents of soil varies in different locations and is constantly changing.” But it’s a good place to start! This site offers the answers to several soil questions like what is soil? Or what are different kinds of soil? It describes soil in very basic easy to understand terms and offers links for further investigation, and some links that are useless for research but entertaining nonetheless. A downside is that it is a dot com site, and not much information in the way of author credentials, as well as not being specific enough at times.  But the site was pretty good over all, it was accurate, easy to navigate, proofread, it had plenty of links and also had a contact address for both of the authors who collaborated to make the site.

"Why Study Soils?" (1998)

http://www2.nau.edu/~doetqp-p/courses/env320/lec1/Lec1.html

    This pristine article written by a trustworthy author and reliable database is easy to read and understand. The article explains why the study of soil is vital to almost every job. It is important in archeology, engineering, food production, and even human history. This article is not only well written, but it is also interesting to read. The topic intrigues the audience and influences them to follow through the studies of soil. Along with the many positives of this website, there are some additional negatives. First, the last time the article was updated was in 1998. An additional downfall is that the website is pretty difficult to navigate making ones interest to know more about soil studies decrease. Overall, the website was a very trustworthy and informative website.

"What is Soil?" (2018)

https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/edu/?cid=nrcs142p2_054280

            This website’s purpose is to define the most basic aspects of soil. The website provides several definitions that allow the reader to fully comprehend the concept. It also defines what the upper and lower boundaries of soil are. The content is very broad and does not go into many specifics which could be detrimental depending on what information is being searched for. The website does lack graphics and it does not give links for further research. The website it backed by the United States Department of Agriculture, however, so it is reliable.

“What is Soil Ecology?” (2014)

http://www.wisegeek.net/what-is-soil-ecology.htm

This site gives examples of what studying soil ecology consists of and what soil ecologists focus on. It talks about the chemical and physical aspects to soil and how soil ecology is involve with environmental issues. The wording of the website is very concise and easy to understand. To be improved, this website could give a little more information beyond the basics to get people more interested in learning about soil ecology.

“What do Fungi and Bacteria do in the soil?” (1998)

http://www.montana.edu/cpa/news/wwwpb-archives/ag/baudr150.html

This website from Montana State University is focused on describing the role bacteria and fungi play in the soil. Bacteria and Fungi have the job of decomposing plant material and turning the elements in the plants into items that can be used to nourish other micro- and macro organisms in the soil. These items also benefit plants that may be planted there in the future. The overall result is “improved soil structure, stability of structure and better drainage and aeration” (Bauder, J. 1998). The site is not very long but it provides a lot of good information that is easy to understand.
