Nitrogen fixation

spreading across the country. With increasing members of society demanding “organic”, it may be time to offer a program specifically for this growing trend. A majority of you already return clippings, use IPM techniques, fertilize with slow release nitrogen, spot treat and minimize pesticide/herbicide applications, which all describe a successful sustainable lawn care program. By offering programs that highlight organic fertilizers during spring applications, you now have the ability to take…

Introduction: Once a plant begins growth, it depends on multiple abiotic factors to continue growing: light, carbon dioxide and water. These three factors affect the growth rate of a plant, causing it to grow quicker or slower. Furthermore, altering these factors may stunt plants growth or improve it. For example, plants require an adequate amount of water to survive. Water hydrates the plant and also breaks down the minerals in the soil. As the plant absorbs the water, nutrients are transported…

The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetic factor is expressed in the plant. Topography Topography is a nonliving factor that refers to the “lay of the land.” It includes the physical features of the earth such as the land elevation, slope, terrain (flat, rolling, hilly, etc.), mountain…

4.1.1 Particulate control. Particulate can be defined or referred to as tiny particles of matter like dust, smoke, soot which are being emitted during agricultural and industrial processes as well as other economic activities. Various methods involved with particulate control operate basic principles. Solid particulate particles are usually isolated from gases where they are controlled by physical procedures like through a settling chamber. Settling chamber is a wide and elongated pipe where…

It was found that the cores were too weak due to an engineering flaw when curing the concrete. Engineers in an effort to save time on the project moved to accelerate the curing process. In order to accelerate the process nitrogen gas was added to the concrete mixture. The nitrogen gas expedited the curing process however there was a cost the came with the accelerated curing. The cores produced using the accelerated process were found to be too weak to withstand certain pressure surges caused by…

And I find chopsticks frankly distressing. Am I alone in thinking it odd that a people ingenious enough to invent paper, gunpowder, kites and any number of other useful objects, and who have a noble history extending back 3,000 years haven't yet worked out that a pair of knitting needles is no way to capture food?" (Gunpowder quotes), this quote talks about how the Chinese made many great inventions like gunpowder. Gunpowder is very important because it created a weapon of mass destruction that…

begin to be absorbed into the blood and tissues keeping in mind that with depth, the chest is being compressed simultaneously. Consequences can be the immediate release of Pn2 and Po2 back into the body causing nitrogen narcosis (Encyclopedia, 2014). 2) Decompression Sickness is when the Nitrogen that was stored in the blood and tissues while descending in the water, forms bubbles within the tissues upon the ascending or pressure decrease (Encyclopedia, 2014). 3) Signs and symptoms of…

1. The distribution of organisms simply means the abundance of organisms on Earth. All organisms are live in different biomes because of their characteristics of survival. Furthermore, all organisms are unique and need certain living conditions. For example, polar bears and lizards will not be able to live in similar biomes because of their characteristics and behaviors on survival. Lizards depend on the sun for energy and heat while polar bears retain heat with their fur to stay warm because…

1. Even though, the eruption of Mount St. Helens volcano was one of the most severe eruptions yet, some plants survived the upheaval. Ecologists were surprised to find the emergence of plants in the mass of ash covered terrain. As the ecologist Dale quoted, “It gave the impression of total lifelessness.” However, roots being guarded in moist soil, resilient plants, and snow sheltering trees were the three main reasons vegetation survived. 2. The plants, and trees that endured the eruption are…

Back on the date of June 18, 1773 Joseph Priestley was in his science lab exploring and studying about the elements. Priestley had done a lot of experiments to find more about the element now known as oxygen. The first experiment dealt with using the previous methods Carl W. Scheele used. Carl W. Scheele was a chemist from sweden, but in his discovery of oxygen he had other people helping him throughout the process. Joseph had thought in his mind, “ If I can do this scientific inquiry on my own,…
