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.

How do you remove fungus from a flower bed?

User Avatar

Asked by Wiki User

To remove fungus from a flower bed, you can start by improving drainage to prevent water accumulation. Prune affected plants to increase airflow and remove any infected plant debris. Consider using a fungicide as a last resort if natural methods do not work.

How is nitrogen fixed in the soil?

User Avatar

Asked by Wiki User

Nitrogen is fixed in the soil through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen gas (N2) into forms that plants can use, such as ammonium (NH4+) or nitrate (NO3-). This process can occur naturally in the soil or can be facilitated by nitrogen-fixing bacteria living in root nodules of certain plants.

How do you acidify my soil?

User Avatar

Asked by Wiki User

To acidify your soil, you can use products such as sulfur, aluminum sulfate, or iron sulfate. Be sure to follow the instructions on the product label to avoid over-acidifying the soil. Test the soil pH before and after application to monitor the changes.

Is soil and fertilizer the same?

User Avatar

Asked by Wiki User

No, soil and fertilizer are not the same. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that support plant growth. Fertilizer is a substance that is added to soil to supply one or more essential nutrients to plants, such as nitrogen, phosphorus, and potassium.

How does manure become soil?

User Avatar

Asked by Wiki User

Manure is a natural fertilizer composed of organic matter. When manure is applied to soil, the nutrients it contains are broken down by soil organisms and released into the soil. Over time, these nutrients help improve soil structure, increase microbial activity, and enhance soil fertility, ultimately contributing to the formation of healthy soil.

Iron in the soil gives this planet it's red color?

User Avatar

Asked by Wiki User

The planet is Mars. Iron in the soil oxidizes, creating iron oxide, also known as rust, which gives the Martian surface its characteristic red color.

Soil analysis of cations and anions?

User Avatar

Asked by Wiki User

Soil analysis of cations involves measuring the concentration of positively charged ions such as calcium, magnesium, and potassium, which are important for plant growth. Anions analysis includes measuring negatively charged ions such as nitrate, phosphate, and sulfate, which are crucial for nutrient availability to plants. Understanding the levels of these ions in soil can help determine the soil's fertility and recommend appropriate fertilization practices.

What is the fine mud carried by rivers called?

User Avatar

Asked by Wiki User

The soil that is deposited by a river to form landforms such as river bars and river deltas is called silt. A river delta is the name of the landform that is created the mouth of a river.

What methods are used to protect soil from erosion?

User Avatar

Asked by Wiki User

Methods to protect soil from erosion include planting cover crops, using mulch or ground cover, contour plowing, terracing, and building retaining walls. These techniques help to reduce the impact of water and wind on the soil, preventing the loss of valuable topsoil.

What type of chemical can be added if soil is too alkaline?

User Avatar

Asked by Wiki User

Compost can be added.Compost consists of rotting plant material such as leaves and vegetables. The plants decompose to give off carbon dioxide gas. Some of this gas dissolves in water to form carbonic acid that reduces the alkalinity of the soil.

Which of the following is a homogeneous mixture a salt water b beef stew c sand and water d soil?

User Avatar

Asked by Wiki User

A) Salt water is a homogeneous mixture because the salt is evenly distributed throughout the water.

How do farmers change the acidity of soil?

User Avatar

Asked by Wiki User

Farmers can change the acidity of soil by adding materials like lime to raise the pH or elemental sulfur to lower the pH. They can also use practices such as crop rotation and cover cropping to help naturally adjust the soil pH levels over time. Testing the soil regularly and following recommendations from soil testing labs can help farmers make informed decisions about adjusting soil acidity.

How does erosion by water cause loss of soil from farms?

User Avatar

Asked by Wiki User

Erosion by water on farms can occur when rainfall washes away topsoil, carrying it downstream. This process can be exacerbated by improper land management practices that leave soil exposed and vulnerable to erosion. Over time, the loss of soil from farms can lead to decreased soil fertility, crop productivity, and water quality.

What Minerals are in Japan?

User Avatar

Asked by Wiki User

Japan is rich in minerals such as copper, lead, zinc, manganese, and gold. It also produces significant amounts of limestone, dolomite, silica, and pyrophyllite. Additionally, Japan is known for its deposits of rare earth elements, which are essential for modern technology.

Why is contaminants in soil hard to remove?

User Avatar

Asked by Wiki User

Contaminants in soil are hard to remove because they can bind tightly to soil particles, making them resistant to removal. Additionally, the size and depth of contaminated areas make remediation a complex and costly process. Depending on the type of contaminant, removal can also be challenging due to the potential for leaching into groundwater or causing further environmental damage.

Which type of soil is the most effective when purifying polluted water?

User Avatar

Asked by Wiki User

Soils with high levels of organic matter, clay content, or iron oxides are effective in purifying polluted water. These soils have the ability to adsorb pollutants and contaminants, improving water quality. Sand or gravel soils are less effective in this regard.

Is dirt and water a solution?

User Avatar

Asked by Wiki User

No, dirt and water do not form a solution. A solution is a homogenous mixture where one substance dissolves in another. In the case of dirt and water, dirt does not dissolve in water but rather forms a suspension where the particles of dirt remain suspended in the water.

Is soil on Neptune?

User Avatar

Asked by Wiki User

No, Neptune is a gas giant and does not have a solid surface like Earth. The outer layer of Neptune is composed mainly of hydrogen, helium, and traces of methane. Therefore, there is no soil or solid ground on Neptune.

How you can change the pH of a soil if it is acidicalkaline?

User Avatar

Asked by Wiki User

To raise the pH of acidic soil, you can add lime (calcium carbonate) to neutralize the acidity. To lower the pH of alkaline soil, you can add sulfur or ammonium-based fertilizers to increase acidity. It's important to conduct a soil test before making any adjustments to ensure you are applying the right materials in the correct amounts.

Why must farmers be careful not to add too much slaked lime to soil?

User Avatar

Asked by Wiki User

Excess slaked lime can increase soil pH to levels that are harmful to plant growth, leading to nutrient deficiencies and reduced availability of essential nutrients. It can also release toxic levels of aluminum or manganese into the soil, further damaging plant health. Overuse of slaked lime can disrupt the balance of beneficial microorganisms in the soil, affecting overall soil health and fertility.

A mixture of small particles of rocks a variety of minerals and humus is called?

User Avatar

Asked by Wiki User

The mixture of small particles of rocks, minerals, and humus is called soil. Soil is crucial for plant growth and provides nutrients, water retention, and support for roots. Its composition can vary based on location and environmental factors.

What is an example of adding nitrogen to soil?

User Avatar

Asked by Wiki User

An example of adding nitrogen to soil is by incorporating organic matter such as compost or manure. These materials contain nitrogen-rich compounds that can be broken down by soil organisms to release nitrogen for plant uptake. Another method is using nitrogen-based fertilizers, which directly supply nitrogen to the soil for plants to use.
