Soil

Soil, by definition, is a earthly compound comprised of biotic (living) and abiotic (non-living) matter that is formed in several layers over millions of years. It is the very component of the Earth that plants need to root themselves and grow in in order to feed all animal life. There are many different types of soil across the globe for each continent and biome, and each type has its characteristics that depict what plants can grow where, when, and how. Questions and answers about soil can be asked and answered here.

Asked by Wiki User

Soil is vital for everyday life:

  1. Food production: Provides nutrients for crops.

  2. Water filtration: Purifies water as it percolates.

  3. Supporting ecosystems: Offers habitat for plants and animals.

  4. Carbon sequestration: Stores carbon, mitigating climate change.

  5. Building material: Used in construction.

How is acidic soil treated?

User Avatar

Asked by Wiki User

Acidic Soil ( pH is low) may be treated with lime, or crushed limestone.

Both these substances rect with the aciudic ions in soil to form a salt, water and carbon dioxide. #

Thereby increasing the pH to about '7'

If you see a farmer putting a white powder on fields, he is liming the field in order to increase the pH from acidic to a more neutral pH.

Here is the chemical eqution.

2H^(+) + CaCO3 = Ca^(2+) + H2O(l) + CO2(g).

NB They do NOT use an alkali, because in may produce an excess of alkali pH > 7.

What causes soils to vary in color?

User Avatar

Asked by Wiki User

Leaving aside the obvious (wet soil looks darker), the amount of organic matter or humus in a soil controls how dark the soil is. Generally the darker a soil is, the "richer" it is considered to be.

What are two ways that soil is often wasted?

User Avatar

Asked by Wiki User

There are two common ways in which soil is often wasted.

First, improper farming practices such as over-tilling or excessive use of chemical fertilizers can lead to erosion and soil degradation.

This not only reduces the overall quality of soil but also harms its ability to support healthy plant growth.

Secondly, urbanization and industrial development often result in the removal of topsoil during construction activities.

Topsoil is the nutrient-rich upper layer of soil, and its removal can seriously deplete vital resources necessary for agricultural purposes.

It's important to address these issues to prevent the waste of soil. Implementing sustainable farming practices, such as crop rotation and organic farming, can help preserve soil fertility and prevent erosion.

Additionally, during construction projects, measures can be taken to protect and preserve topsoil, including using erosion control techniques and proper soil management.

By being mindful of our farming and development practices, we can contribute towards the conservation and sustainable use of soil for future generations.

Why does soil float in water?

User Avatar

Asked by Yuroarai

Soil typically doesn't float in water; instead, it tends to sink. The buoyancy of an object in water is influenced by its density. If soil particles are denser than water, they will sink. However, if there are pockets of air or organic matter in the soil, they might trap enough air to make the soil appear buoyant temporarily.

Does soil give off oxygen?

User Avatar

Asked by Wiki User

NO!!!

However, green plant life growing out of the soil does.

A green leaf plant takes in carbon dioxide. Under the process of photosynthesis ( uv/sun light is needed), the plant breaks down the carbon dioxide, into its component elements.

The carbon component remains in the plant as biomass. The oxygen component is released back intoi the atmosphere. This maintains the oxygen level in the atmosphere, at about 20%.

It is a natural process that humans neither hear, see nor smell, so short of scientific invesigation we cannot tell how fast it procedes. However, it must go on at a fast rate in order to remove CO2 from the atmosphere and replace it with oxygen.

In chemistry/biochemistry/geochemistry ,there are three cycles going on all the time. they are the nitrogen cycle, oxygen cycle and carbon cycle. I'll leave you to investigate these cycles.

Why do we loosen up the soil before sowing?

User Avatar

Asked by Wiki User

Size up the area you want loosened, start in a forward spot, Jab in a pitchfork, step on it to sink it, twist it back & forth (1-2, 1-2, 1-2), pull the handle about halfway down toward you, remove pitchfork, step back one step, jab in pitchfork, repeat as above until entire area you sized up (or a desired portion) is done to your liking.

Put down the pitchfork, take a break, go get a tasty iced tea. It's all about the tea. We do it for the tea. Enjoy the tea, and rest assured that now the seed you plant will be better able to germinate, and let their little roots sink in for better nutrient extraction.

How does soil erosion affects animals?

Asked by Wiki User

To a point it could. The erosion could destroy the plants and the ability of trees to grow taking away the animals natural habitat. And the erosion could also destroy the land where they use to build their homes,nest,den.from one article i read this in turn could mess with their ability to have offspring making their numbers dwindle.and eventually causing them to become endangered or extinct.

What kind of soil do tomato's like?

User Avatar

Asked by Wiki User

Tomatoes prefer well-draining soil that is rich in organic matter. The ideal soil for tomatoes has a slightly acidic pH level between 6.0 and 6.8. It is important to avoid heavy clay soils that can retain too much moisture and hinder root development.

Which 2 layers of the soil are least likely to contain humus?

User Avatar

Asked by Wiki User

the two layers are

sub soil

The layer of soil that has little or no humus in it is the subsoil. The top layer of the soil has the most humus in it because the dead leaves fall from the plant and go back into the soil.

Does potting soil absorb water?

User Avatar

Asked by Wiki User

Yes, potting soil has the ability to absorb water. It is designed to retain moisture and provide a suitable environment for plants to grow. The composition of potting soil typically includes materials such as peat moss, vermiculite, and perlite, which have high water-holding capacities.

How do people contribute to soil erosion?

User Avatar

Asked by Wiki User

People can contribute to soil erosion through activities such as deforestation, improper agricultural practices, overgrazing, and construction without proper erosion control measures. These actions can result in the removal of vegetation cover, which reduces the soil's ability to absorb and retain water, leading to increased erosion by wind and water. Additionally, the disturbance of natural landscapes can increase the vulnerability of soils to erosion.

What is added to soil to lower the pH What is added to soil if the pH is too low?

User Avatar

Asked by Wiki User

To lower the pH of soil, acidic materials are added such as sulfur, iron sulfate, or aluminum sulfate. If the pH is too low, or too acidic, lime or dolomite can be added to raise the pH and make the soil more alkaline.
