Arches National Park This area is changing and here is why. The story of Arches begins roughly 65 million years ago. At that time, the area was a dry seabed spreading from horizon to horizon. The striking red rock features we see today would have been buried thousands of feet below you, raw material as yet uncarved. Then the landscape slowly began to change due to erosion (National Park Service). The national park lies on top of an underground evaporite layer or salt bed, which is the main…

Did you know that the Chinese Ring- Necked Pheasant is native to Asia and was brought here for a game bird? There are 30 different types of pheasants in 5 groups. There is a major difference in the colors between the male and female birds. The male have a lot of colors and patterns on their feathers and the females are very dull and grey looking so they can stay hidden in the fields with their young. The males can range in colors from white to almost black and they can also have multi colored…

objective of the experiment is to explore the process of simple analysis techniques and representative sampling in determining soil nutrient levels. Soil samples collected from Flinders Campus were used to determine their pH, salinity, ammonium, nitrate, phosphate, and nitrite levels. Introduction Unless there is a specific problem detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in most…

The barrel cactus is easily distinguished from other cacti because of its cylinder-shaped body. It is one of the largest cacti in North America reaching a staggering eleven feet tall. Running down the spines are 3-4 inch spines and on top are rings of yellow-green or red blossoms. Native Americans used to boil them into cabbage-like stews. They would also grind up the pulp and extract the water. Another plant native to deserts is the brittle bush. IT is a small deciduous shrub which grows as a…

Virginia soil and environmental conditions. The objective of this bulletin to provide effective fertilization to laws in an environmentally sound manner. The bulletin has following main topics 1. Selecting a fertilizer 2. Season of Application - When to apply 3. Factors Affecting Nutrient Management 4. How Much Fertilizer to Apply Per 1000 Square Feet? Under selecting fertilizer it provide comprehensive but covering all essential elements for fertilizer selection. Requirement of soil test…

Argiustolls which is of the Mollisol order (National Cooperative Soil Survey 2000). It is found only within the Gallatin County of southwest Montana. Blackmore soils are not very prevalent within southwestern Montana. The exact location of the Blackmore soil type is found specifically 1100 feet south and 1800 feet west of the northeast corner of section 27, T. 2S., R.6E. This area has an elevation of 4,800 to 5,500 feet. This type of soil can be found on relict stream terraces with slopes…

Tillage is the physical or mechanical agitation of the soil with tools and implements result in good tilth for better germination and subsequent growth of crops. Continuous practice of modifying the state of soil in order to provide favorable conditions for growth of crops is known as tillage addiction. Physical manipulation of soil is intended to destroy weeds, incorporate crop residues and amendments into soil, increase infiltration and reduce evaporation, prepare seedbed and break hard layers…

Rainforest and ruining the home of the world’s most endangered tribe, the Awá, along with many other native tribes (Chamberlain, 2012). Deforestation simulations have shown an increase in temperature and a decrease in rainfall, which cause desertification, soil erosion, and flooding (Lejeune, Davin, Guillod, & Seneviratne, 2015). Not to mention, forests are home to 80 percent of the world’s biodiversity. Deforestation is liable for the loss of 137 plant, insect and animal species daily (Cho,…

carbon in ocean, soil, vegetation and geologic formations. Oceans store the most however soil holds 75% of carbon on land and therefore play a leading role in the balance of carbon global cycle (Carbon Sequestration in Soils, 2000). Organic carbon can be lost in soil from accelerated mineralization and erosion (Biala, J., 2011). Therefore, the break down of organic materials will produce carbon dioxide and water into the atmosphere. Composting can put organic carbon back into soil with a low…

Discussion The nitrate and phosphate levels shown in through my data relates to my hypothesis since it proves that the epigeic earthworms in the soil increased the nutrients in the soil, since the average nitrate and phosphate levels increased from tests 1-3. The results from this experiment showed that the control group increased their phosphate levels more so than the experimental groups, which contained the red wriggler earthworms. This could have been due to high amounts of Ca²⁺ in the water…
