What are the method of collecting undisturbed soil sample?
One method is using a soil auger to collect a cylindrical sample by rotating it into the ground. Another method involves using a split-spoon sampler driven into the ground to obtain a undisturbed soil core. Careful excavation with a soil core sampler can also help collect undisturbed soil samples.
Give a reason why it is necessary to leave the gas jar undisturbed in a soil profile activity?
Leaving the gas jar undisturbed in a soil profile activity ensures that any gas released from the soil is accurately captured and measured. Disturbing the gas jar can lead to loss of gas or inaccurate results, affecting the analysis of the soil's gas composition.
What are the advantages of conducting an experiment on undisturbed soil sample compared to disturbed soil sample?
A disturbed sample is one in which the structure of the soil has been changed sufficiently that tests of structural properties of the soil will not be representative of in-situ conditions, and only properties of the soil grains (e.g., grain size distribution, Atterberg limits, and possibly the water content) can be accurately determined. An undisturbed sample is one where the condition of the soil in the sample is close enough to the conditions of the soil in-situ to allow tests of structural properties of the soil to be used to approximate the properties of the soil in-situ.
What is disturbed soil?
Disturbed soil refers to soil that has been altered, disrupted, or damaged by human activities such as construction, excavation, or agriculture. This can result in changes to the soil structure, nutrient levels, and overall ecosystem functions. Disturbed soil may be more prone to erosion, compaction, and decreased fertility compared to undisturbed soil.
How can you separate soil particles from a jar of water?
You can allow the jar of water and soil particles to sit undisturbed until the particles settle at the bottom. Then, carefully pour out the water, being mindful not to disturb the settled particles. You can repeat this process of settling and pouring until most of the soil particles are removed.

Where can the mobile runway edge sheave be anchored?
soil w/ CBR of 15 undisturbed soil any location
What is the minimum CBR value required for a MAAS installation on undisturbed soil?
7
How long has the soil been undisturbed in the tropical rainforest?
The time frame for undisturbed soil in a tropical rainforest can vary greatly depending on the specific location. In some places, soil may have been undisturbed for hundreds or even thousands of years due to minimal human interference, while in other areas, deforestation and land use changes may have disrupted soil within the past few years or decades.
What is the definiton of rhizons?
Sampler used to extract pore-water from undisturbed soil and sediments

What happen when a mixture of soil and water is left on the table undisturbed for along time?
dissolve in water
In an emergency concrete installation what is the minimum number of bolts required in each anchor plate?
on undisturbed soil

If the MAAS is going to be installed on undisturbed soil that is less then 7 CBR what anchoring method is recommended?
Dead-man and anchor chain

What does the no-till system of conservation tillage entail?
leaving the soil undisturbed from harvest to planting except for nutrient injection and controlling weeds primarily with herbicides
