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.

Do humans cause soil erosion?

There are many ways, many very indirect. The chief cause is the cutting covering or destruction of plant life.

What are the 5 soil forming factors?

The five soil forming factors are climate, organisms, topography, parent material, and time. Climate influences the rate of weathering and decomposition, organisms contribute to the organic matter content, topography affects water movement and erosion, parent material determines the mineral composition, and time allows for soil development processes to occur.

Is soil texture important for plant growth?

No Most seeds will germinate in water. The best way to test seeds for germination is to place the seeds between two layers of wet paper towel and put them in a plastic sandwich bag in a warm place. After a few days, the seeds will begin to sprout. This is also the way I start seeds which are difficult to germinate, e.g., gourd seeds. When the seeds sprout, I take them out of the paper towel and plant them in soil.

What causes the soil and rock particles to fall?

Soil and rock particles fall due to gravity, which pulls them downwards towards the Earth's surface. Factors such as erosion, weathering, and human activities can also lead to the movement of soil and rock particles.

How do you separate mixture of soil and rainwater?

You can separate a mixture of soil and rainwater by using a process called filtration. Pour the mixture through a filter such as a coffee filter or paper towel to capture the soil particles while letting the water pass through. The soil will be trapped in the filter, allowing you to collect the clean rainwater separately.

Which machine will work best to dig a hole in the soil?

An excavator would likely work best for digging a hole in soil. It is designed specifically for digging tasks and has features such as a bucket that is well-suited for excavation work. It is also able to handle different types of soil conditions efficiently.

When does horizon close?

Horizon's closure is set for January 13, 2023.

What is inorganic soil made of?

Inorganic soil is made up of mineral particles such as sand, silt, and clay. These particles do not contain organic matter, which distinguishes them from organic soil. Inorganic soil often has good drainage properties and can be suitable for growing certain types of plants.

What is a land management technique that limits topsoil loss?

One land management technique that limits topsoil loss is conservation tillage, which involves reducing or eliminating the amount of soil disturbance during agricultural practices such as planting and cultivation. This helps to protect the soil structure and preserve organic matter, reducing erosion. Other techniques include planting cover crops, practicing crop rotation, and implementing soil conservation practices like terracing or contour plowing.

How do floods cause soil erosion and soil erosion causes floods?

Floods cause soil erosion by carrying away topsoil and sediments as the water flows rapidly over the land, stripping away the soil. This can lead to the loss of fertile soil for agriculture and damage to aquatic ecosystems. On the other hand, soil erosion can cause floods by depositing large amounts of sediment into rivers and streams, which can block water flow and increase the risk of flooding during heavy rainfall events.

What does soil consist of and what factors determine its fertility?

Soil consists of a mixture of minerals, organic matter, water, air, and living organisms. Factors that determine soil fertility include the soil's pH, nutrient levels, organic matter content, microbial activity, and texture. These factors influence the soil's ability to support plant growth and productivity.

Why is the loss of organic matter in soil so serious?

The loss of organic matter in soil is serious because organic matter is essential for soil health. It provides nutrients for plants, improves soil structure, and helps retain water. Without sufficient organic matter, soil quality and fertility decline, leading to reduced crop yields and increased vulnerability to erosion and drought.

How is an earthworm adapted to living in the soil?

Earthworms have adapted to live in soil by having a slimy, cylindrical body that allows them to move easily through tunnels. They have bristles on their body to help anchor themselves in the soil and they can absorb oxygen through their skin. They also have a specialized digestive system to break down organic matter in soil for nutrition.

How plentiful are bacteria in water in soil?

Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.

What happens to soil if you add lime?

Adding lime to soil helps to neutralize acidity, improve the soil structure, and provide essential nutrients like calcium to plants. It can also boost microbial activity and enhance the availability of other nutrients in the soil.

What happen if there is no water in soil?

If there is no water in the soil, plants will not be able to absorb the essential nutrients they need for growth and development. This can lead to wilting, stunted growth, and eventually, death of the plants. The absence of water can also impact soil structure and biological activity, affecting the overall health of the ecosystem.

What is the most common soil type found in Florida Type A Type B are Type C?

The most common soil type found in Florida is Type B. These soils are sandy and well-drained, making them ideal for agriculture and development. Type A soils are more clayey and prone to flooding, while Type C soils have limitations for construction due to shrink-swell properties.

How does topsoil retain water?

Topsoil retains water through its ability to absorb and hold onto moisture due to its organic matter content and porous structure. This allows the water to infiltrate into the soil and be stored for plant uptake, supporting plant growth and soil health.

How does lichen make soil?

Lichen can help create soil by secreting acids that break down rocks into smaller particles, which eventually become the base for soil formation. The organic matter produced by the lichen also contributes to the development of soil by providing nutrients for other plants to grow. Over time, lichen can play a crucial role in the soil-building process in barren or rocky environments.

Does soil turn into mud when water is poured into it?

Soil can turn into mud when water is poured into it if there is a high clay content in the soil. Clay particles can absorb water and create a muddy consistency. Sandier soils are less likely to turn into mud when water is added.

Who measured the mass of the soil in which a plant grew?

Scientists or researchers typically measure the mass of soil in which a plant grows. This is done using tools such as weighing scales to determine the weight of the soil before and after the plant growth period. The difference in weight is used to calculate the mass of the soil in which the plant grew.

How much soil does a marigold need?

Marigolds typically have shallow roots and don't require a lot of soil depth. A planting container or garden bed with growing medium that is 6-8 inches deep should provide sufficient soil for the marigold plant to thrive. Make sure the soil is well-draining and enriched with organic matter for best results.

What is a soil that is characteristic of the humid eastern US is?

A soil characteristic of the humid eastern US is Alfisols. Alfisols are typically fertile soils with a clay-rich subsoil that forms in temperate and humid climates. They are common in areas with deciduous forests and agriculture in the eastern United States.

Does an ice cube melt faster on soil?

An ice cube may melt faster on soil compared to a solid surface like concrete or metal due to the soil's ability to absorb and retain heat. Soil has higher thermal conductivity and can transfer heat more efficiently to the ice cube, accelerating the melting process. Additionally, soil may contain organic matter that can further increase the melting rate by providing insulation and trapping heat.

How does soil affect earth an its landscape?

You could litter on it causing it to erode away. Then no plants can grow and then we won't get as much healthy food as we do now. Don't litter to help the environment and soil. Also, soil helps a tree grow so you don't want to waste paper because then we need more trees and for trees to grow, we need soil. Use both sides of the paper and recycle.
