Soil tests

The 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, Phosphates, Potassium, and Percent Sand, Silt, and Clay. The first test we conducted was the Percent Water Content; to determine the value, we massed soil in a tin cup, heated the tin cup and soil in the microwave for 24 hours, and then re-massed…

Science Fair Purpose The purpose of this experiment is to find out which type of soil amplifies side-to-side shaking the most in an earthquake. Hypothesis My hypothesis is that sand will amplify the shaking the most because, liquefaction loosens up the soil which can make buildings slide. Materials To build your shake table, you will need: Packing tape Coffee can lid, or any flat plastic lid with approximately 3/8" lip that can fit under the shake table tray Marbles, or any small balls of the…

Introduction: Soil samples where collected to test at Green River College, King County Washington, Sec 16 T21N R05E, W.M. in the gator pond retention area. Testing was done every half chain, for a distance of 528 feet to the north/south, 16 lines. Plots to the east/west where done until the water no longer flowed into the water shed. Data collected included, amounts of sand silt and clay, the amount of gravel, and dominate and co-dominate species in a 4 foot radius and the density of each plot.…

8.5.3 INTERPRETATION Comment on the properties of the soil GENERAL REMARKS: This test is useful when the soil is soft and its water content is near liquid limit. The following precautions are necessary when using field vane shear tests: 1. The vane must be rotated soon (within 5 minutes) after insertion into the depth to be tested as delays of one (1) hour to one day may lead to overestimation of strength by 10% to 20% respectively. 2. Standard rate of rotation is 6 degrees per minute. 3.…

An important chemical property of soil that can affect herbicide persistence is pH. Soil composition is a physical factor determined by the relative amounts of sand, silt, and clay in the soil (the soil texture), as well as by the organic-matter content. The types and abundance of soil microorganisms present in the soil make up the microbial aspects of the soil environment. Generally, soils high in clay, organic matter, or both have a greater potential for herbicide persistence because of…

430-011. This article available as PDF format as well as web base information. Specifically Virginia soil and environmental conditions. The objective of this bulletin to provide effective fertilization to laws in an environmentally sound manner. The bulletin has following main topics 1. Selecting a fertilizer 2. Season of Application - When to apply 3. Factors Affecting Nutrient Management 4. How Much Fertilizer to Apply Per 1000 Square Feet? Under selecting fertilizer it provide…

Mehta, Rutvij J. Sonecha, Parth D. Daxini, Parth B. Ratanpara, Miss Kapilani S. Gaikwad et.al. (2014): They used black cotton soil from Rajkot Gujrat and determined various engineering properties of the black cotton soil having medium to low swelling property. They stabilized the black cotton soil by using lime. Changes in the engineering properties of the black cotton soil before and after the stabilization by lime were observed on the basis of tests such as liquid limit, plastic limit,…

AHCSOL303 Assignment 3- soil amelioration report 1.i have a soil that does not absorb water, and when i water it the water pools on the surface and does not infiltrate. What is wrong with my soil? The soil could either be hydrophobic or heavily compacted. Hydrophobic soil is where the surface tension does not allow for infiltration of water because of a waxy layer, which cause the water to form into little beads and can form a pool on the surface. Heavily compacted soil is soil that has…

of the soil with tools and implements result in good tilth for better germination and subsequent growth of crops. Continuous practice of modifying the state of soil in order to provide favorable conditions for growth of crops is known as tillage addiction. Physical manipulation of soil is intended to destroy weeds, incorporate crop residues and amendments into soil, increase infiltration and reduce evaporation, prepare seedbed and break hard layers to facilitate root penetration and overcome…

The site characterisation process our class used is only applicable to a single house. I was assigned to the T3 test hole. The result in the texture test meant that the modified percolation test had to be carried out for silt/clay subsoil found onsite in LIT Tipperary. Deviations from Procedures According to the EPA code of practice (2009) the T test hole should have the following…
