Soil

Over-farming, deforestation, erosion, and poor land management practices can lead to soil depletion. These activities strip the soil of essential nutrients, decrease its fertility, and reduce its ability to support plant growth. Restoring soil health often involves implementing sustainable agricultural practices and replenishing lost nutrients through organic amendments.

Leaching typically occurs in the topsoil layer of the soil profile. This is because the topsoil is the uppermost layer where organic matter and nutrients are present, making it susceptible to leaching when water percolates through it.

A plant that grows in soil and holds little water is that is does not need nutrient.

After a tornado picks up dirt, the dirt particles are carried along with the tornado's swirling winds. As the tornado moves, it can deposit the dirt particles when its winds weaken or when it dissolves. The dirt can then settle back to the ground once the tornado dissipates.

I manhandled the whole nine yards of top soil into the rose garden all by myself.

Are there more than one variety of top soil available for delivery?

I would like to have six cubic yards of top soil delivered tomorrow if possible, please.

Alluvial soil is fertile because it is rich in minerals, nutrients, and organic matter that have been carried and deposited by rivers and streams over time. The regular deposition of these materials replenishes the soil, making it highly productive for agriculture. Additionally, the fine texture of alluvial soil allows for good water retention and drainage, which is ideal for plant growth.

Soil with only large grains is called coarse-grained soil. This type of soil is typically well-draining due to the size of the particles, but it has poor water and nutrient retention capabilities.

Decayed plants and animals compose the soil. When plants and animals die they decay and become part of the soil. New plants grow causing herbivores to come and eat the

plants. Well you know how the cycle goes and then the dead animals and plants become part of the soil once again

No they can't. They can only obtain carbon dioxide from the leaves through the gas exchange at the stoma (singular: stomata). However, plants can get water, ions, and mineral salts from the soil.

Soil is made of 3 main layers: topsoil, subsoil and the layer of parent material.

The topsoil contains most of the humus (which is a dark organic material of the soil), it is formed from the decay of various organisms

The thick layer of soil below topsoil is subsoil, it is lighter in colour in comparison with the topsoil and often contains a lot of clay. Water carries minerals an other materials down into this layer and most tree roots grow down into the subsoil

The bottom layer contains large rocks, this is the material from which the soil above is partly formed. The bottom layer is the parent material, these rocks break down into gravel, sand and clay that become part of the subsoil

No, soil is not considered an ore. Ores are naturally occurring materials that contain a metal or other valuable mineral in sufficient amounts for it to be extracted and processed profitably. Soil, on the other hand, is a complex mixture of organic matter, minerals, water, and air that forms the uppermost layer of Earth's crust where plants grow.

Clay soil is known for its sticky texture when wet due to its fine particles that have a tendency to clump together. This stickiness can make it challenging for plants to establish roots and for water to drain properly. Improving clay soil may involve adding organic matter to improve its structure and enhance drainage.

Abiotic factors in an ecosystem. They are non-living components that affect the living organisms within an ecosystem. These components are essential for the survival of plants and other organisms in the ecosystem.

The amount of rain affects the soil by influencing its moisture content. Heavy rainfall can lead to waterlogging and erosion, impacting soil structure and fertility. In contrast, drought conditions can dry out and harden the soil, making it difficult for plants to grow.

Positive gravitropism, as the roots grow towards gravity by growing downwards into the soil.

because soil is vital to healthy plant growth. soil is useless in the bottom of a lake and at the bottom of storn drains
Almost everything you eat can be traced back to the soil. Fruits and vegetables come from plants grown in soil. Even the milk in ice cream comes from cows that ate plants growing in soil.
water is becoming so scarce in many places and other things are lacking so it is rare to have usable soil.when you have it, its like gold to some people who dont get it very often. :)

The percolation rate of sandy soil is typically high due to its larger particle size and loose structure, allowing water to move through it quickly. This can lead to faster drainage and potentially lower water retention compared to soils with smaller particle sizes.

Peat is a dark brown color, resembling the earthy tones of soil. It is often associated with natural organic materials found in wetlands and marshes.

It can be done using the following steps:-

-Sedimentation: Let the jar rest in place for some time. The soil particles settle down.

-Decantation: Pour the water into another jar. Care should be taken so that the settled particles are not poured out.

-Filteration: Filter the remaining water through a filter paper or strainer.

1. Bacteria: Bacteria play a crucial role in soil health by decomposing organic matter and fixing nitrogen, making nutrients available to plants.
2. Fungi: Fungi form symbiotic relationships with plant roots, helping plants absorb water and nutrients from the soil.
3. Earthworms: Earthworms improve soil structure through their burrowing activities, aerating the soil and increasing its water-holding capacity.

Farmers take care of soil by rotating crops, using cover crops to protect it from erosion, practicing minimal tillage to preserve its structure, and applying organic matter like compost and manure to improve soil health. They also monitor soil conditions regularly to ensure proper nutrients and pH levels for crop growth.

That would be an aquifer.

The time water stays at the surface of the soil can vary depending on factors like soil type, slope of the land, and weather conditions. In general, water will evaporate or infiltrate into the soil within a few hours to a few days. Heavy rain or compacted soil can lead to water pooling on the surface for longer periods.
