When Is A Soil At Permanent Wilting Point?
A soil is at permanent wilting point when a plant can no longer extract water from it, even when soil is fully saturated. This occurs when soil water tension becomes so high that it is held too tightly by soil particles for plants to access. At this point, plants wilt and may eventually die due to lack of water.
Does soil require energy for metabolism?
The short answer is: No, soil is never metabolized so energy is not required for its metabolism. More specifically: By definition, only living organisms metabolize anything. And, when they do, energy is always required. But the metabolism of soil never occurs as soil itself contains no nutrient and remains undigested and is excreted unchanged when a living organism ingests it. Two examples of ingesting soil come to mind among higher organisms: Earthworms do eat some wet soil so as to extract vegetable matter from it, but they metabolize only the latter and excrete the soil unchanged and therefore not metabolized. Elephants are also known to eat some soil from which their organism selects useful bacteria to keep but excretes the soil undigested and therefore not metabolized. Among lower organisms, plants do not ingest soil but extract soluble minerals and electrolytes from it through their roots and metabolize these using energy.
How do you separate aluminum from soil?
With no great ease! Problematically, aluminum is not magnetic so there goes the easy option. To extract aluminum from ore or in prohibitively small quantities, from soil....it might be a smart idea to take the soil sample and heat it to a high temperature - burning the organic matter and liquidising the aluminum for easier collection. The problem here is, you would end up with aluminum oxide. Then, massive amounts of electricity is sent through the aluminum oxide to separate the oxygen molecules. What remains is a powder that is grittier than baby powder, almost with a texture of regular table salt.
What is gasoline pH scale?
Gasoline does not have a pH scale like acids or bases because it is a mixture of hydrocarbons and additives. Gasoline is typically neutral or slightly basic in nature, with a pH close to 7. pH scale is not commonly used to measure gasoline properties.
What helps put nutrients back into soil?
Worms pull leaves down into the ground to eat, and some are left down there and decompose down, leaving their nutrients. Also, if you rotate crops with turnips they are good for putting nutrients into the soil, so farmers will get a better crop of whatever they next plant in that field.
I need to win a scholarships and i can win one at a science fair so what is a good science fair project?
well you can see what types of plants extract oil from soil.... science class 101 <:
What is the means of hybrid cars?
So-called "hybrid" cars can be powered by more than one type of fuel. i.e. gasoline/electric - gasoline/diesel - etc. So-called "hybrid" cars can be powered by more than one type of fuel. i.e. gasoline/electric - gasoline/diesel - etc.

When full a 22-gallon gas tank holds 129.8 pounds of gasoline. estimate the weight of one gallon of gasoline?
To estimate the weight of one gallon of gasoline, divide the total weight of gasoline in the tank by the number of gallons. So, 129.8 pounds divided by 22 gallons equals approximately 5.9 pounds per gallon. Therefore, one gallon of gasoline weighs about 5.9 pounds.
Why is gasoline so expensive?
gasoline is running low in the world
What do you mean by permanent wilting point?
The permanent wilting point is the soil moisture content at which plants can no longer recover from wilting as the soil water potential is too low for them to extract water effectively. At this point, the plant cells have lost so much water that they are unable to regain turgidity even if the soil moisture increases.
When gasoline and water are mixed together which one ends on top?
Gasoline has a density of around .71g/mL while water's density is 1g/mL so Gasoline floats on Water.
Why is gasoline an especially dangerous substance?
Gasoline is very flammable and fairly toxic by inhalation and swallowing. The real danger though is familiarity. So many people are so familiar with gasoline as an every day substance that they fail to take care of a fairly dangerous substance. That is what makes it ESPECIALLY dangerous.
Some small engines require a mixture of oil and gasoline gasoline evaporates easily what conclusion can be drawn about the polarity of the engine oil?
haha so which one of you chilldress ipc people asked this one haha

What are the pros and cons of gasoline cars?
Gasoline is relatively cheap compared to other types of fuel, such as hydrogen fuel cells. Gasoline is convenient if one is intending to travel a great distance, as other fuel sources do not have as great a density as gasoline does. Also, gasoline stations are everywhere, so it's not difficult to find a place to refuel.However, gasoline creates pollution. There is also not much gasoline left on this planet, as it is a fossil fuel and therefore there is a limited supply--and gasoline is non-renewable. In addition, gas prices are going up, so it will probably not remain cheap for too much longer.
What are positive effects of gasoline?
gasoline is hurting our environment Pollution is being made because of automobiles; people are dying in the war to fight for oil or gas in Iraq and the gasoline prices have effect on hotel rooms in the United States.
