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 the series of changes that occur where the ecosystem has been disturbed but soil and organisms still exist?
Secondary Succession
What disease is caused by bacteria in soil?
Foot and mouth disease. Tuberculosis is found in soil and may stay dormant for many years. When the dirt is disturbed the bacteria may become airborne and infect the lungs.
Why does soil erosion increase when soil is plowed?
Because the conditions that hold it together is disturbed and it is easily washed along by water. theincreased surface exposed to the air also tends to dry it out making it more prone to blown about by the wind.
What is soil erosions?
The denudation of the soil cover and subsequent washing down is described as soil erosion. The processes of soil formation and erosion, go on simultaneously and generally there is a balance between the two. Sometimes, this balance is disturbed due to human activities like deforestation, over-grazing, construction and mining etc., while natural forces like wind, glacier and water lead to soil erosion.breaking down of soil time period can cause land slides.
Secondary succession?
Plants grow on soil like where it was disturbed but there was still soil left.

What is low till farming?
A method of farming in which the soil is disturbed as little as possible, and only when necessary. Compare to no-till farming in which the only soil disturbance is just that which is necessary to plant the seed.
What disease is caused by bacteria in soil?
Foot and mouth disease. Tuberculosis is found in soil and may stay dormant for many years. When the dirt is disturbed the bacteria may become airborne and infect the lungs.
How do you get hystoplasmosis?
You can get histoplasmosis from the fungus Histoplasma capsulatum. The fungus is typically found in soil and when disturbed releases harmful elements into the air that can then be inhaled by humans.
Where does a bloody-nosed beetle lives?
On the soil . typically in low vegitation areas. when it feels disturbed or messed with it excretes a red fluid from its mouth. (:
Why are former grasslands among the productive regions?
The Grasslands soil is usually deep, dark, and rich. Because a lot of its soil is very rich, a lot of the grasslands have been destroyed and most of it disturbed, due to farming.
What do milipedes eat?
Millipedes find their food in leaf litter and soil. They eat decaying plant material.
