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.

What factors in an area help determine the type of soil the thickness of one layer and their compositions?

Factors such as climate, parent material, topography, organisms, and time can influence the type of soil, its thickness, and composition in an area. For example, a warm and wet climate can lead to thicker soil layers with high organic content, while rocky parent material can result in shallower soil layers with a different composition. The presence of vegetation and the amount of time for soil formation also play roles in determining soil characteristics.

What is percolation of waterhow it is different for different types of soil?

Percolation of water refers to the movement of water through soil or porous materials. It can vary for different types of soil due to differences in porosity, particle size, and organic matter content. Sandy soils typically have higher percolation rates due to their larger pore spaces, while clay soils have slower percolation rates because of their smaller pore spaces and tendency to compact.

In order to keep the soil fertile farmers often change the crop that is grown in a field every two to three years. What is this process called?

This process is known as crop rotation. Crop rotation helps prevent soil depletion and disease buildup by alternating different types of crops in the same area over a period of time.

What are five factors that affect soil development?

  1. Climate influences soil development through temperature and precipitation patterns.
  2. Parent material, or the underlying rock or sediment, impacts the composition and properties of the soil.
  3. Organisms such as plants, animals, and microorganisms contribute to soil formation through processes like decomposition.
  4. Topography, including factors like slope and aspect, affects soil development by influencing water drainage and erosion.
  5. Time is an important factor in soil development, as soils evolve over centuries or millennia through the accumulation of organic matter and weathering processes.

What term best describes the combination of soil and water?

The term that best describes the combination of soil and water is "soil moisture." Soil moisture refers to the water content present in the soil, which is essential for plant growth and ecosystem stability.

What is Residual soil?

has bedrock as its parent material

What soil makes the north china plain a good wheat farming area?

The North China Plain benefits from fertile alluvial soil, rich in nutrients from sediment deposits carried by the Yellow River. This soil is well-suited for wheat cultivation due to its high fertility, good drainage properties, and ability to retain moisture. The combination of these factors makes the North China Plain an ideal location for wheat farming.

What is Soil conversion?

Soil conversation is the management of soil to present its destruction.

P.S. Are u in Kinawa Middle School?

How can a farmer convert acidic soil to neutral soil?

A farmer can convert acidic soil to neutral soil by adding materials such as limestone or lime to increase the pH level. Regular testing of the soil pH is important to monitor progress and determine the amount of amendment needed. It's also beneficial to incorporate organic matter into the soil to help improve its overall health and fertility.

In which location would soils develop faster?

Soils typically develop faster in warm, humid climates with high levels of vegetation and organic matter input. This is because the combination of temperature, moisture, and vegetation promotes organic matter decomposition and mineral weathering, which are key processes in soil formation.

What are First step of soil formation?

The first step of soil formation is the weathering of the parent rock material. This process is facilitated by physical, chemical, and biological agents such as temperature, water, wind, plants, and bacteria. Weathering breaks down the parent material into smaller particles, setting the stage for further soil development.

What is parallel to horizon?

A line parallel to the horizon would be level and run parallel to the Earth's surface without intersecting it. This is commonly seen in landscapes where structures or objects appear parallel to the horizon.

If bedrock has been partially weathered then what is it known as?

If bedrock has been partially weathered, it is known as saprolite. Saprolite is the result of chemical and physical weathering processes acting on bedrock material over time, breaking it down and creating a softer, more weathered layer.

How do lichens encourage soil formation on barren rock?

Lichens secrete acids that break down bare rock, releasing minerals. When lichens die, they decompose to form organic matter that helps build up soil. Over time, this process contributes to soil formation on barren rock surfaces.

What Compost helps preserve the health of soil because it .?

Compost helps preserve soil health by improving soil structure, increasing water retention, providing essential nutrients to plants, and promoting beneficial microbial activity. Over time, compost also helps reduce soil erosion and suppress plant diseases.

What is the name of the process by which water carries material from the upper soil to the lower levels?

The process is called leaching, where water transports nutrients and compounds from the topsoil to deeper layers, affecting the soil's composition and fertility.

What Mixture of weathered rock organic matter water and air?

Soil is a mixture of weathered rock particles, organic matter, water, and air. These components together create a fertile medium for plant growth and provide habitat for a variety of organisms.

Is A thick mass of tough roots called loess kept the fertile soil of the prairies in place and held on to moisture?

No, loess is a fine, silty soil deposited by the wind, not a mass of roots. The roots of prairie grasses helped hold the soil in place and retain moisture.

What is a vertical section through all of the soil horizon is called?

A vertical section through all of the soil horizons is called a soil profile.

How does the removal of forest cover effect soil erosion?

The removal of forest cover increases soil erosion because tree roots help bind the soil together, reducing erosion caused by water or wind. Without tree cover, soil is more exposed to the elements and can be easily washed or blown away. This can lead to loss of topsoil and decreased soil fertility.

What do you recomment a farmer if the soil in his farm is acidic Why?

I recommend the farmer to test the soil pH and then adjust it by adding lime to raise the pH level. Soil acidity can hinder plant growth by reducing nutrient availability, so correcting the pH can help improve crop productivity.

What is sandy topsoil said to be because water drains quickly through the spaces between the sand particles?

Sandy topsoil is said to be well-draining because water flows easily through the large spaces between the sand particles, allowing excess water to move downward quickly. This promotes good aeration and helps prevent waterlogging, making sandy soil suitable for certain plants but also requiring proper irrigation and fertility management.

What are the three horizon of a mature residual soil?

The three horizons of a mature residual soil are the A horizon (topsoil), B horizon (subsoil), and C horizon (weathered rock material). The A horizon contains organic matter and is the most fertile layer for plant growth. The B horizon is rich in minerals leached from the topsoil. The C horizon is the least weathered and consists of partially weathered bedrock.

Why can not use sand instead of clay for making pots?

Sand lacks the plasticity and cohesion that clay possesses, making it unsuitable for forming and maintaining the desired shape of a pot during the firing process. Clay contains fine particles that can be molded and shaped easily when wet, while sand does not have the same qualities required for pottery making.
