Ohene Akuoko 10/24/12 Soil and Environment Classification of Soil based on Sedimentation Rates Introduction Soil is a naturally occurring substance covering the upper level of Earth’s Continental Crust which sits upon Earth’s highest layer of geological area the lithosphere. Soil is actually nothing more but the remnants of the Earth’s Mountains and the life that has lived on this planet through the natural process of erosion and time on Earth. A good soil is said to be composed of 5 % organic

1. INTRODUCTION The stability and life of any structure – a building‚ an airport‚ a road‚ dams‚ levees – depend on the stability‚ strength‚ and deformation of soils.[1] Unfortunately‚ due to the uncertainties of the world’s natural materials‚ the study of geotechnical engineering‚ and soil mechanics in particular‚ is both challenging and necessary. The following report is a compilation of the results acquired as a result of two laboratories performed by Group 13 at McMaster University on February

Name: Raaga Singireddy Mrs. M-K/Science Date: 6/3/2013 Pd. 2 Soil Lab QUESTION: What Soil Recipe will grow the best Pea seed? CLAIM: I believe that soil made up of 30% silt‚ 25% Water‚ 15% humus 5% Sand‚ 5% of Clay‚ and the assuming the other 25% is air‚ will grow the best pea seed. MATERIALS 100 Milliliter Dixie Cup Ground Clay _ Silt Water

Lab: Investigating Soils Observations/Data Record the observations and/or data you collected here. Describe the color‚ feel‚ and appearance of each soil sample. Sample 1: Play ground sand: khaki colored‚ feels rough‚ has more sand than rocks. Sample 2: Potting soil: black/brown-ish colored‚ feels some what soft‚ has little pieces of bark (woody stem‚ branches‚ and roots of plants.) Sample 3: Backyard soil: Orange-red‚ feels lumpy‚ muddy look alike. What is the texture of each soil sample

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

Activity 1 – Water Holding Capacity & Capillary Action of Soil 1. Grain size and the amount of air space between particles. 2. Water-holding capacity determines the amount of water a soil is capable of holding. Since water is a necessity of any agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater

1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and

Soil Microbe Lab Antibiotics are chemicals produced by substances that kill or inhibit the growth of bacterial cells (Hurney et al 2013). These microbes‚ such as bacteria found in the soil‚ may seem like they would be harmful to the human body because they attack cells‚ however they are very efficient at only attacking the bacterial cells. Actinomycetes are one of the more common groups of these soil microbes known to produce antibiotics. Antibiotics work because they target specific aspects
