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.

10,730 Questions

The formation of soil starts with what?

The formation of soil starts with the weathering of rock and minerals. This process can be physical, chemical, or biological, leading to the breakdown of rocks into smaller particles that eventually form soil.

Describe three horizons of a residual soil?

Horizion A:

  • Surface litter-fallen leaves and partly decomposed organic matter
  • Topsoil-organic matter/living organisms/rock particles

Horizon B:

  • Zone of leaching-dissolved/suspended materials moving downward
  • Subsoil-larger rock particles with organic matter, and inorganic compounds

Horizon C:

  • Rock particles-rock that has undergone weathering
  • Bedrock-solid rock layer

Where is silt and soil deposited?

Silt and soil are typically deposited in areas near water sources such as rivers, streams, and lakes. They settle in these areas due to the action of water carrying and depositing sediment as it flows. This process is known as sedimentation.

Is the soil in the Middle East rich?

The soil in the Middle East varies depending on the location. Some areas have fertile soil due to river deposits and favorable climate for agriculture, while other areas have sandy or arid soil which can be less productive for farming. Overall, the region has a mix of soil types.

Where is soil erosion happening the most?

Soil erosion is happening most in areas with deforestation, overgrazing, inappropriate agricultural practices, and urban development. Regions experiencing high precipitation, steep slopes, or vulnerable soil types are also more prone to soil erosion. Addrressing these factors through sustainable land management practices is crucial in mitigating soil erosion.

What are two things that can happen to water when it soaks into the soil?

When water soaks into the soil, it can either be absorbed by plant roots for growth and metabolism, or it can percolate deeper into the ground to replenish underground aquifers and contribute to groundwater recharge.

Is New Mexico's soil fertile?

This answer depends on what part of New Mexico but many parts of New Mexico are fertile and many are not for example one area that is extremely fertile is Penistaja. This area is great for crops and even livestock.

Five things about the make up of soil?

Soil is composed of five distinct horizons. In order from closest to the surface to farthest away from the surface, they are: the O Horizon, A Horizon, E Horizon, B Horizon, and C Horizon. The O Horizon - or "organic" horizon, is composed mainly of loose and partly decayed organic matter such as leaves and teems with microscopic life. The A Horizon is mineral matter mixed with some humus (the decayed remains of animal and plant life). Together, the O and A Horizons make up what is known as topsoil. Below the A Horizon is the E Horizon, which is made up of light colored mineral particles. It contains little organic matter. The B Horizon is an accumulation of clay transported from above as water percolates through the upper horizons. The B Horizon is also known as "subsoil". The O, A, E, and B Horizons are collectively called "Solum", or "True soil". The C Horizon is partially altered parent material. Although this material is undergoing changes that will eventually turn it into soil, it still possess most of the characteristics of the bedrock underneath and has not crossed the boundary that separates regolith from soil.

The damp soil within a forest in which a mushroom grows?

The damp soil in a forest provides a suitable environment for mushrooms to grow as they thrive in moist conditions. This soil is rich in organic matter and nutrients, which support the growth of fungi like mushrooms. The presence of decaying plant material in the soil also contributes to the mushroom's ability to decompose and obtain nutrients.

What decomposes soil?

Various organisms such as bacteria, fungi, insects, worms, and other decomposers break down organic matter in the soil, which then contributes to the decomposition process. Additionally, weathering processes and chemical reactions also play a role in breaking down rocks and minerals in the soil.

The Free Soil Party was an example of a an?

The Free Soil Party was an example of a political party in the United States that opposed the expansion of slavery into newly acquired territories. It was active in the mid-19th century and eventually merged with the Republican Party.

What is the connection between soil organisms and soil fertility?

Organisms in theground consume organic matter and deposit the remnants as nutrients and minerals in the soil in a form that plant life can more easily absorb. Larger organisms, like small animals, burrow in the soil which increases the airiness of the soil.

How does bacteria in soil change nitrogen compounds?

Bacteria in soil can convert nitrogen gas from the atmosphere into a form that plants can use through a process called nitrogen fixation. Other bacteria can convert organic nitrogen compounds into ammonia through the process of ammonification, and some bacteria can convert ammonia into nitrate through nitrification. These processes are essential for the cycling of nitrogen in the soil ecosystem.

How might garbage dumps harm the soil?

well...I'm not sure but it might be harmfull for the soil because, if you dump all that it will

be realy smelly and rotten and soil can not have that .it is just bad for the soil like that if you realy think of it.

How many 25 liter bags of soil in a cubic yard of soil?

There are approximately 5.67 25-liter bags of soil in a cubic yard of soil.

Does soil erosion cause water pollution?

Yes. Soil erosion causes water pollution. The pollution from mud in the water is nowhere near as dangerous to people as the pollution from sewage. Likewise, excess fertilizer runoff creates algae blooms which poison people. Some health food nuts claimed blue green algae is good for you. Many cattle have died from drinking water from ponds filled with blue green algae. Fertilizer drained from farm fields into ponds caused the poisonous algae to grow. The pollution caused by soil erosion is bad. The pollution caused by fertilizer runoff is worse.

Will there ever be a war on us soil?

It is difficult to predict the future with absolute certainty, but historically, there have been conflicts on US soil. As a country, the US works to prevent such scenarios through diplomacy, defense initiatives, and international relationships. The focus is on maintaining peace and security within its borders.

What did the early Slavs do to make their farming soil fertilized?

Early Slavs used crop rotation and fallowing to help fertilize their farming soil. By rotating different crops seasonally and letting fields lie fallow, they allowed the soil to replenish nutrients naturally. They also used manure and compost to enrich the soil for better crop yields.

Why are soils different colors?

Soil can be different colors due to variations in the mineral content, organic material, and moisture levels. For example, brown soil usually contains a lot of organic matter, while red soil may have a higher iron content. Soil color can also indicate its fertility and drainage properties.

What are three methods farmers use to conserve soil?

  1. Crop rotation: Planting different crops in the same area in consecutive seasons helps prevent soil erosion and maintains soil fertility.
  2. Cover cropping: Growing cover crops like legumes or grasses helps protect the soil from erosion, adds organic matter, and improves soil structure.
  3. No-till farming: Leaving crop residue on the soil surface and not tilling the land reduces soil disturbance, improves water retention, and enhances soil health.

How do living organisms help soil?

Living organisms help soil by breaking down organic matter and releasing nutrients that can be used by other plants. They also contribute to soil structure by creating pore spaces that allow for better drainage and root growth. Additionally, some organisms like earthworms help to aerate the soil, improving its overall health.

How surface litter horizon is described by?

The surface litter horizon, also known as the O horizon, is typically described as a layer of organic materials such as leaves, twigs, and other plant debris that accumulate on the soil surface. It plays a crucial role in providing nutrients as it decomposes, improving soil structure, and supporting the growth of vegetation.

What are the soil conditions in the tropical rainforet?

Soil conditions in the tropical rainforest are typically nutrient-poor due to the rapid decomposition of organic matter. The warm and moist climate leads to high rates of weathering and leaching, which can wash away nutrients. The soils are often acidic and low in organic matter, making them susceptible to erosion.

What holds soil on hillsides trees or plants?

Plants, including trees, help hold soil on hillsides by spreading their root systems, which anchor the soil in place. The roots also absorb water and help prevent erosion by reducing runoff. Trees, with their larger and deeper root systems, can be particularly effective at stabilizing soil on hillsides.

Is non fertile soil renewable or nonrenewable?

Non-fertile soil is generally considered renewable because it can be improved through various sustainable agricultural practices, such as using cover crops, composting, and crop rotation. By enhancing soil fertility through these methods, non-fertile soil can become productive and sustainably support plant growth for future generations.
