CHAPTER 4 EXPERIMENTAL RESULT AND DISCUSSION 4.1 General This chapter discusses the result of experiment of soil properties at the Orthosiphon Stamineus plot, INSAT as describe in chapter three. The experimental were aimed to study the impact of compaction on soil properties at different depth for Orthosiphon Stamineus cultivation in order to determine the suitable soil classes, and propose best depth to plough the area to in order to have high yield with cost effective practice to manage
clay are of extreme importance in soil science. Plant growth, and hence crop production, within any environmental condition is largely controlled by soil structure which results from reactions involving clay. The active clay material in .soil, particularly in combination with small amounts of organic matter, exerts a tremendous effect on soil properties. This effect may be on structure (the arrangement of soil particles), or on consistence (the response of the soil to mechanical manipulation). Where
Introduction: Wetland soils are widely diverse. They are found from the arctic to the tropics. They can be mineral or organic, seasonal or year-round, marine or freshwater. The one thing they all have in common is that, for at least part of the year, they are saturated with water. This saturation has a significant impact on the soil's characteristics such as the biota, chemistry, and physics. However, over the past century more than half of all the wetlands in the United States have been drained

Building safe, adequate, durable roads over permafrost soil presents unique challenges to the construction industry. It is not suprising that the mechanisms that lie behind these challenges are explained by the laws of physics. Consequently, as concerned professionals from the engineering community look for inovative ways to deal with the permafrost specter, it is in the realm of physics where they look for the elusive techniques that will enable the extension of the transportation infastructure
Up until my freshman year of high school, when I studied biology, I’ve never found anything appealing about science. During my elementary and middle school years, I learned a bit of chemistry along with physics, biology, and earth science. Early on this school year, I realized that the problem was not the subject of science itself, but rather, the manner in which I had learned it. My science classes had rarely involved hands-on labs or written reports, and the classes were filled only with lifeless
Rain Forest Soils of La Selva Tropical rain forests across the globe are currently threatened by massive deforestation for logging, grazing, and cultivation (Otzen 1993). Such land-use practices alter temperature regimes (Fernandes and Sanford 1995) as well as ground, soil, and surface water, flora, fauna, and microorganisms (Otzen 1993). These changes may result in a loss of soil organic matter, a decrease in soil fertility (Garcia-Oliva et al. 1994, Tissen et al. 1994), severe soil erosion (Otzen
drew conclusions. I learned about Newton’s Law and about forces of gravity, while learning how to problem solve and be a scientist. These were meaningful ways of learning. I have to point out the fact that my most favorite experience was going on the Physic day to six flag because concept such as the newton’s law of motion, force and acceleration and many others we put to practice on real life scenario. In addition to that, I was able to enjoy all the rides of the park. This experience just makes more
Science branches out to the research of anything ranging from life to the latest technology. It has a vital influence in the development of new things that might improve our everyday life. Some researchers help us learn what not to do with certain elements. A chemist to be specific, does exactly that. According to Emporia State University, a chemist is a scientist who focuses his/her studies toward that involves of chemicals. Becoming a chemist isn’t easy, but it is a career that contributes to society

The Boscastle Floods Heavy seasonal rainfall is a common feature of the climate of South West England and has been documented many times, sometimes it has little affect on the landscape and just drains away but very occasionally it has far more destructive effects. On the 16th of August this year, massive amounts of rainfall over the North Cornish coast caused a disaster on a scale that has not been seen since 1952. A flash flood devastated the small coastal town of Boscastle, this investigation
different soil solution. Background Knowledge: Plants make there own food by photosynthesis. They need light and CO2 from the atmosphere and the water absorbed from the soil. Plants also need very small quantities of minerals for healthy growth. Mineral ions are absorbed through the roots from the dissolved chemicals compounds in the soil. When garden centres sell bottles of “Plant Food” they are selling solutions of some of the important minerals; these can be added to the soil in which
Nitrogen as a Fertilizer, Nutrient, or Pollutant Nitrogen can always be a fertilizer, nutrient, or pollutant depending on the circumstances and the environment it is in. As a fertilizer, nitrogen can be extremely useful in aiding the growth of many plants. As a nutrient, nitrogen is essential to many plants growth and survival. As a pollutant, nitrogen can not only affect the plant at the given time but be very detrimental many years down the road. No matter where you go nitrogen will always
Location Brimbank Park (coordinates 37.7340° S, 144.8370° E) is located in the Maribyrnong Valley (hollowed by the Maribyrnong River), near the Melbourne suburb Keilor. It is intersected by the Maribynong River and the M80 highway, which reveals the adaptive nature of the natural environment in a growing urban area. (Parks Victoria, 2013) Figure 1: Map of Brimbank Park (Google Maps, 2014) Geology Brimbank Park consists mainly of sedimentary rock, due to its close proximity to the Maribyrnong
The Mallee Region of Victoria Location and Contents: The Mallee region of Victoria is situated in North-West Victoria and covers an area of around 44,000 square kilometres. The region is known to be associated with the adjacent land of South Australia and New South Wales and is also recognised to join with the Wimmera and Loddon regions of Victoria. Also, because of the large area which the region covers and the diversity it beholds, it is sometimes distinguished into two sub-regions, the north
on the grounds had evidence of radioactive contamination. The soil, sediment, surface water, and ground water on the site had high levels of depleted uranium. On some of the soil and sediments, Poly Chlorinated Bi-phenyls were recorded. The buildings and structures on the grounds were as well contaminated with depleted uranium and other hazardous substances. In 1998, the company conducted a voluntary partial cleanup of contaminated soils under The Massachusetts Department of Environmental Protection
itself, although it is available in the nearest town. The adoption of hybrid and improved seed technologies, the use of chemical fertilisers and plant protection measures, mechanization (use of tractors, sprinkler irrigation and power sprayers) and soil and water conservation measures, have been contributing significantly, to increase farm productivity. Genetically modified seeds have been adopted in the village, including Sona Masuri and Hamsa in paddy, GCH-4 in castor and LRG-11, LRG-41, PRG-158
People relate to landscapes through tactile and visual experience of surfaces around them, beneath their feet and in their hands. Textures are most immediate and close physical contact with the landscape. Ploughing, grazing, clearance – create distinctive textures of surface, some of them deliberately created for the properties of the texture itself. Textures incorporate time; they are result of a slow but constant change of the very texture of surface. Mundane practices which might have a minimum
test show that the potting soil is on par with the ARHS soil in every way besides humus. However, when the soil was moist, it appeared that the potting mix soil contained more humus, thereby making me conclude that there was an error. Also, Our group (the one responsible for Potassium) used the wrong test tube to measure the potassium levels in the ARHS soil. However, the potassium levels in the ARHS soil are, without a doubt, still lower than the potting soil's. Soil quality analysis: In terms
