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 makes some women so fertile?

Some women are just more fertile than others by nature. There are unsupported claims that certain foods or lifestyle choices make certain women more fertile. Younger women tend to be more fertile than older women.

What makes a land an agricultural land?

It is reasonably flat or gently hilly, and the soil has to be ideal for growing crops on. Other agricultural land that is not ideal for growing crops on that has highly variable terrain and rocky soils can otherwise be used for grazing livestock on.

Where do you found saline soil in the world?

Saline soil is the type of soil that has salts in it. This type of soil is found all over the world, but the levels of salts will vary from place to place. Saline soil is mostly found in drier regions.

What is the function of the sun and the soil?

The sun provides energy for photosynthesis in plants, which is essential for their growth and production of food. Soil provides a medium for plants to grow in, anchoring roots and providing nutrients and water for their development. Both the sun and soil are critical components in the ecosystem for sustaining plant life.

What ways could soil losse its fertility?

Soil can lose its fertility due to erosion, leaching of nutrients, depletion of organic matter, compaction, and contamination with pollutants or chemicals. These factors can reduce soil health and productivity over time.

What process moves water down through soil?

Infiltration is the process of water moving vertically down through the soil.

What steps are taken by a farmer to prepare soil?

A farmer prepares soil by plowing or tilling to break up compacted soil, adding organic matter like compost or manure to increase fertility, testing soil to determine nutrient levels, adjusting pH if needed, and cultivating to create a seedbed suitable for planting.

What soil types has the richest in organic material?

Peat, muck, and loam are some soil types that are richest in organic material. Peat and muck soils have high organic content due to decomposed plant material, while loam soils have a balanced mixture of sand, silt, and clay with high organic matter content.

What is the condition that causes a permafrost?

Permafrost is caused by prolonged freezing of the ground, where the temperature remains below freezing for two or more years consecutively. It is typically found in polar regions and high mountain areas where the cold temperatures prevent the ground from thawing completely.

Which best explains the reastionship between soil characteristics and the movement of water?

Soil characteristics such as texture, structure, and porosity influence how water moves through soil. Soil with fine particles like clay tends to hold water tightly, while sandy soil allows water to pass through quickly. Soil structure affects water infiltration and retention, and porosity determines how much water can be stored in the soil.

If it rains a lot which is more likely to flood sand or clay soil?

Clay soil is more likely to flood than sand because clay soil has smaller particles and can hold more water. This means that it can become waterlogged quickly during heavy rain, leading to flooding. Sand, with its larger particles, drains water more easily and is less likely to flood.

How silt is produced?

Silt is produced through the erosion of rocks and soil particles, usually by natural forces like water or wind. It is made up of fine mineral particles, smaller than sand but larger than clay. Silt deposits can accumulate in rivers, lakes, and oceans, affecting water quality and ecosystems.

Why do gardners dig soil before sowing seeds?

Digging the soil before sowing seeds helps to loosen the soil, improving aeration and allowing roots to grow more easily. It also helps to break up compacted soil, remove weeds, and incorporate organic matter or fertilizers for better plant growth. Overall, digging the soil creates a more favorable environment for seeds to sprout and plants to thrive.

Why does the gram seed need loam soil to grow?

Gram seeds require loam soil to grow because loam soil provides good drainage, aeration, and moisture retention, which are essential for the healthy growth of gram plants. The balanced mixture of sand, silt, and clay in loam soil ensures that the roots can easily penetrate the soil to access nutrients and water.

What type of soil is in shimla?

The soil in Shimla is predominantly classified as brown forest soil and mountain soil. Brown forest soil is fertile and rich in nutrients, suitable for agriculture, while mountain soil is typically rocky and less fertile due to its high elevation and rugged terrain.

What is field capacity?

Field capacity is the maximum amount of water soil can hold after excess water drains away. It is the point at which gravity overcomes the forces of water absorption and retention in the soil. Field capacity helps determine when plants need watering and ensures proper soil moisture for crop growth.

How can you separate pebbles from soil?

One way to separate pebbles from soil is by using a sieve. Pour the soil and pebbles mixture onto the sieve and shake it gently. The pebbles will remain on top of the sieve while the soil passes through. Another method is to handpick the pebbles from the soil manually.

What is the sub-specialization of soil science?

One sub-specialization of soil science is pedology, which focuses on the formation, classification, and mapping of soils. Another sub-specialization is soil fertility, which deals with the chemical, physical, and biological factors that affect the availability of nutrients for plant growth in soils.

What was the meaning of the golden horizon?

The phrase "golden horizon" typically symbolizes hope, opportunities, or a promising future. It can evoke feelings of optimism, success, or a new beginning.

How long does it take to produce soil?

The time it takes to produce soil varies depending on factors like climate, vegetation, and geological processes. On average, it can take hundreds to thousands of years for soil to form from the weathering of rocks, decomposition of organic matter, and other natural processes. Human activities like agriculture and land use can also affect soil formation rates.

Why do sandy soils leach out nutrients rapidly while clay soils retain nutrients?

Sandy soils have larger pore spaces and lower cation exchange capacity, which allows nutrients to move through the soil more easily. Clay soils have smaller pore spaces and higher cation exchange capacity, which helps retain nutrients by holding them in the soil and preventing leaching.

What is the best way to keep potting soil from compacting?

To prevent potting soil from compacting, include perlite, vermiculite, or coconut coir in the soil mix to improve aeration and drainage. Avoid overwatering your plants, as excess moisture can lead to soil compaction. Regularly loosening and fluffing the soil with a small rake or fork can also help prevent compaction.

What factors influence the formation of new goals and needs?

Factors that influence the formation of new goals and needs include personal experiences, societal norms, economic conditions, life stages, and relationships with others. These factors shape an individual's priorities, aspirations, and desires, leading to the identification of new goals and needs.

What is bigger 20 quarts or 20 lbs of potting soil?

20 lbs of potting soil would be bigger than 20 quarts, as quarts measure volume (liquid), while pounds measure weight.
