Degradation of soil resources is still the most serious and widespread threat to humankind. Soil has an important role to play in the global environment of food security, water security, climate stability, biodiversity, and ecosystem services (McBratney et al., 2014). Worldwide research has increased awareness that soil resources have influenced by human management and practices. Soil quality assessment provides a better understanding and awareness how soil resources are needed as an essential ecosystem services…
Laboratory Report 2: Soil Texture, Bulk density and Porosity
The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm. The size of the particles influences the…
Soil erosion is one of the most serious threats in our world. Humans cause 40% of soil erosion. Soil erosion is topsoil, which is organic soil made up with rich nutrients. Erosion can be caused by careless farming techniques that lead to water erosion. When it is raining and you are walking to class you can see soil erosion where they have been working beside the English building. Soil erosion and water erosion is practically the same thing. No one will ever notice soil erosion because nobody…
Plant Science - Seed germination and growth
The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas?
Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7.
Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…
Boreal, Coniferous, and Deciduous Forests
Boreal, deciduous, and coniferous forests each possess distinctive traits and soil characteristics. Forests soils give important contributions in nitrogen and phosphorus transformations. These transformations are dependable on the weather conditions of the forest and the type of vegetation it contains. Soil mineralogy and organic matter also play an important role in the nitrogen and phosphorus transformations on the forest floor.
Boreal forests are…
Thanks to modern technology, there is more than one way to grow vegetables. After receiving the challenge from BEST Robotics that included the lettuce and tomato hydroponic stand, one question plagued many of the team members ' minds. What is hydroponics? It is the technique of growing vegetation without soil. This process is rich in history and science, and is important to the Kansas farming industry.
Though the word hydroponics is fairly new, different cultures have been growing plants…
population. The quality of soil is of paramount importance when it comes to planting crops. A major factor attributed to soil quality is the presence of earthworms. Earthworms are very important in the world of agriculture and can help maximize crop yields.
In this study, the effects of earthworms on varying soil pHs and soil density were viewed. Earthworms (Lumbricus terrestris) are very beneficial for the soil. They change the structure and composition of the soil, they alter water movement,…
The purpose of this experiment is to find out which type of soil amplifies side-to-side shaking the most in an earthquake.
My hypothesis is that sand will amplify the shaking the most because, liquefaction loosens up the soil which can make buildings slide.
To build your shake table, you will need:
Coffee can lid, or any flat plastic lid with approximately 3/8" lip that can fit under the shake table tray
Marbles, or any small balls of the…
There is a handful of aspects that go along with healthy soil such as nutrients essential to plants, beneficial microorganisms, and organic additives important in organic farming systems because of the integration of biodiversity; allowing overall healthier lifestyles to all individuals willing to take initiative. The health of the soil is represented by the health and rigor of the plants growing within it. Organic farming is not only beneficial for the earth’s surface but it is…
Mulloon institution to us. Then we started our research with Forest LFA, including landscape organization assessment (LOA) and soil surface assessment (SSA). Firstly, we set up a 50m transect running directly up and down the slope and mapped patches and interpatches on this transect. We regarded the place where resources could be accumulated as patches, like grass, shrubs, logs or trees. Then we made soil surface assessment by choosing 3 points in each patch type randomly and collecting 11…
