What is the percentage of sand silt and clay in a sample of soil?
depends on the kind of soil, each kind would have different composition, in fact the kind is defined by the percentage of sand,silt and clay it has.
What percentage is soil?
5% minerals 45% air and water 50% organic material
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 general appearance of the soil sample?
Brown.
In which type of soil would you expect to see most bubbles when water is mixed with the soil sample?
clay soil
What is the percentage of sand silt and clay in a sample of soil?
depends on the kind of soil, each kind would have different composition, in fact the kind is defined by the percentage of sand,silt and clay it has.
What soil has air in it?
every soil has air in it..... its the percentage of air present which is different for different soils and also depends how frequently the land is plowed.....
How do you say soil has water content in?
The water content of soil is expressed as a percentage, i.e. the percentage of the soil that is water. To calculate, weigh the mass of a sample of soil. Let this be W. Then dry the soil in an oven (be careful not to burn it) and weigh the dry soil. Let this be D. The soil moisture content, M = W-D/W x 100.
A typical soil sample is an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.
What is the percentage of silt and clay in a sample of sand?
depends on the kind of soil, each kind would have different composition, in fact the kind is defined by the percentage of sand,silt and clay it has.
What percentage is soil?
5% minerals 45% air and water 50% organic material
What is the general composition of a soil sample?
The general composition of a soil sample will be some sand, some silt, some clay, and some organic matter, plus a certain amount of microbial life, air and (unless it's completely dried out) some water.
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.
How do you convert milliequivalent to percentage?
This depends on what you would like to use the value for. If analysing a soil sample, it would be best to report the value per 100g of soil as this is the current convention. So, meq% = (meq/ 100 g soil) x 100
What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
How can porosity be measured?
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
How do you neutralize soil after fertilized?
To neutralise a sample of soil, you must determine the pH of the soil sample either acidic or alkaline. Add lime (e.g. Limestone) to acidic soil to neutralise it. And add sulphur to alkaline soil which will neutralise it.
