Introduction: Vanadium is a hard‚ silvery grey metal. Vanadium was discovered by Andrés Manuel del Río‚ a Spanish-born Mexican mineralogist‚ in 1801 [1]. Some sources say Vanadium is soft because it is ductile [1]. Vanadium is harder than most metals and steels [1] It is resistant to corrosion and it is stable against alkalis‚ sulfuric and hydrochloric acids[1]. It is oxidized in air at about 933 K (660 °C‚ 1220 °F) [1]. This paper will discuss the effects of Vanadium on the environment and Vanadium’s

with a wide mouth. While it is possible to use something with a small opening‚ it is much easier to add plants if your container has a wide mouth. You don’t want your plants touching the sides of your jar; so the wider the bowl the more plants and soil you’ll be able to fit. A large container will allow for a greater choice of types and size plants as well as the option of fitting in decorative elements. 2. Choose your Plants When considering terrarium plants‚ look for plants that like low

primarily south-facing slopes‚ which often receive direct sunlight. The soil type of this ecosystem is Benfield. The parent material for Benfield soil is pedisediment over residuum weathered from shale. Benfield soil is moderately deep‚ well drained‚ and has a slow permeability rate so it is very capable of retaining moisture and is good for plant growth. Often in the tall grass prairie‚ areas of higher soil moisture content and deeper soil depth‚ experience lower species richness and a higher density of

Effects of Erosion Jose Castro ENV/310 July 23‚ 2014 Wendy Armstrong Significance of Soil Soil is a very vital component for plants that helps them grow and thrive in the environment they are in. Erosion is causing soil to dissipate and it is putting a lot of strain on different plant species. In my paper I will discuss the effects erosion has on the environment and I will provide different ways to eradicate or control erosion. I will also discuss the consequences that erosion will provide

Kamm EVS-1001 Everest University Online Individual Work Week 5 Soil erosion has become a serious problem for many ecosystems. Erosion occurs when the soil and hummus particles are removed from their location by wind and water (Wright & Boorse‚ 2014). This process causes the soil to erode and become ‘barren” and exposed to the elements (Wright & Boorse‚ 2014‚ p. 276). There are three major contributing factors to soil erosion: overgrazing‚ over cultivation‚ and deforestation. The purpose

The pH‚ humus content‚ texture‚ water retention capacity and air content of the soil can have an effect on the ecosystem. - Soil pH + soil pH is the acidity or alkalinity that is present in soil. + the best pH for soil to grow in is between 6‚0 and 7‚5 pH. + some plants will only grow in specific pH levels. + the pH levels are determined by the type of rock the soil is made from.
