Environmental Science Lab Assignment: Soil Testing (Essay.

Soil testing is an important diagnostic tool for determining the nutrient needs of plants and for environmental assessments. Some soils are inherently deficient in plant nutrients. Other soils had sufficient levels of nutrients in the past, but removal with crop harvest has depleted the reserves. Thus, soil testing is widely accepted and used.

You can also use a soil pH meter in your garden instead of pH test paper. This instrument has a metal electrode probe attached to a meter that has a display for you to read the test results. Typically, you press the probe into the soil to a depth of 4 to 5 inches and leave it for 1 minute.

Soil investigation must be undertaken to determine the bearing capacity of the soil, its settlement rate and the position of the water table. One of the easiest methods is to dig trial pits and visual inspections carried out then samples with minimum disturbance are collected for subsequent laboratory testing. Where possible, drilling should be.

Commercial and recreational gardeners are showing a growing interest in taking accurate pH measurement of soil samples.The pH of soil indicates more than its alkalinity or acidity strength; it affects the relative availability of nutrients, the soil life, and the type of plants that will thrive. The common range of soil pH varies from 4.0 to 8.0; the range of soil pH for optimal availability.

Soil Nutrient Analysis: Nitrogen, Phosphorus, and Potassium. JoVE, Cambridge, MA, (2020). Principles. When chemically isolated from soil, nutrients can be detected using this technique. Nitrogen and phosphorus, typically found in the form of nitrates and phosphates, are extracted with a chemical extractant that will bind the nutrient of interest.

The constant head permeability test is a common laboratory testing method used to determine the permeability of granular soils like sands and gravel containing little or no slit. This testing method is made for testing reconstituted or disturbed granular soil samples.

Consolidated Undrained Triaxial Testing of a Fine Grained Soil. Introduction A consolidated undrained triaxial test was carried out by 16 separate groups to give a broad appreciation of soil behaviour by plotting the resulting effective stress paths.
