  • Unified Soil Classification System

    practicals in the laboratory. The data were used to identify and classify soils for engineering applications. The data were tabulated using Unified Soil Classification System (USCS) method, which is non-laboratory test and 2 classification of soils based on laboratory test. The two laboratory test classify soil methods are Classification of soil based on particular size distribution and Classify soil based on Atterberg Limits. The soil samples from sites known as bore hole and called BH1, BH2, and BH3. I.b.

  • The Influence Of Climate Change In Global Climate

    carbon dioxide, and other greenhouse gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things, including soil microorganisms” ( Brady, Weil 2008). Changes in atmospheric concentrations of carbon dioxide, temperature, and precipitation amounts and patterns will modify the soil plant system, and influence decomposition rates which will have impacts…

  • Soil Test Lab Report

    purpose of this lab was to test for which soil type would be best for food production. The tests included Forest Soil, Floodplain Soil, and Garden Soil. We predicted that garden soil will have the best properties for food production because we expected it to have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates,…

  • Bulk Density And Porosity Lab Report

    Laboratory Report 2: Soil Texture, Bulk density and Porosity Introduction Soil Texture The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm. The size of the particles influences the…

  • The Importance Of Nutrients In Plants

    2.1 Soil The soil is a major source and natural medium for plant growth which has a direct impact on yield and quality of crops growing on it. 2.1.1 Nutrients in soil Most plants raise by absorbing nutrients from the soil. Soil is a major source of nutrients needed by plants for growth and development. There are two main classification of nutrients in the soil; Macronutrients and Micronutrients. Carbon (C), Hydrogen (H), and Oxygen (O) are also essential for plant growth, but not considered…

  • What Is Organic Farming Essay

    Introduction There is a handful of aspects that go along with healthy soil such as nutrients essential to plants, beneficial microorganisms, and organic additives important in organic farming systems because of the integration of biodiversity; allowing overall healthier lifestyles to all individuals willing to take initiative. The health of the soil is represented by the health and rigor of the plants growing within it. Organic farming is not only beneficial for the earth’s surface but it is…

  • Blackmore Series Essay

    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 of approximately 0-15% and…

  • Biochar Case Study

    climate change, as well as for sustainable soil management. But before this can be seriously implemented and developed into policy, scientific evidence must be expanded to fully cover implication of its use on soil properties, processes and functions (Verheijen et al 2012). Until this has been comprehensively quantified, regulations have a higher likelihood of unsuccessfully mitigating potential risks associated with the use of biochar, and creating information asymmetries. The compilation of…

  • Pullman Research Paper

    1.Soil forming factors 1) Climate- The climate of the Pullman series leans on the side of ustic and is in fact a Paleustoll, but can boarder on aridic at times. Ustic is an intermediate between udic and aridic with the winters being relatively dry, and the growing season is characterized by plant available moisture between significant periods of drought. The Pullman series meets this descriptions, in that it’s driest periods lie between July and August, and then December through February, with…
