Soil

antarctic soil differs from other soil because it is formed from volcanic rocks

A soil is at permanent wilting point when a plant can no longer extract water from it, even when soil is fully saturated. This occurs when soil water tension becomes so high that it is held too tightly by soil particles for plants to access. At this point, plants wilt and may eventually die due to lack of water.

Soil particles are classified based on size: sand particles are the largest, followed by silt, and then clay particles are the smallest. Sand particles are between 0.05mm and 2mm in diameter, silt particles are between 0.002mm and 0.05mm, and clay particles are less than 0.002mm in diameter.

Soil sustains life by providing essential nutrients and water for plants to grow. It also serves as a habitat for various living organisms such as insects, bacteria, and fungi that contribute to nutrient cycling and soil health. Additionally, soil helps regulate the Earth's temperature and acts as a filtering system for water.

Soil structure affects the characteristics of soil in many ways. Some soil is not good for farming if it is too rocky. Other soil is perfect for farming and needs little more than regular tending to yield good crops. Different soils yield different organisms as well.

Air pockets found in soil are called pore spaces or soil pores. These spaces exist between soil particles and contain a mixture of gases such as oxygen, carbon dioxide, and nitrogen. They are critical for maintaining proper aeration and facilitating nutrient uptake by plant roots.

The C horizon, also known as the parent material horizon, contains only partly weathered rock. This layer is located just below the B horizon and above the solid bedrock of the R horizon in the soil profile. It is characterized by a mixture of weathered rock fragments and some organic matter.

Constantly smelling dirt could be due to environmental factors like living near construction sites or gardening frequently. It could also be related to conditions like sinus issues or poor indoor air quality. I recommend consulting a healthcare provider if this persists.

The change of soil becoming wet due to rain is a physical change. The soil's state changes from dry to wet without any alteration in its chemical composition.

The most important role of soil is to support plant growth by providing nutrients, water, and anchorage for roots. Soil also helps in the cycling of nutrients, filtering water, and providing habitat for a diverse range of organisms.

The four main ingredients in soil are minerals (like sand, silt, and clay), organic matter (like decomposed plants and animals), water, and air. These components provide the necessary nutrients and structure for plants to grow.

"Soil type CA" sounds like it is an abbreviation for a soil type on a soil map. You will have to consult that soil map or the soil map's makers to find the answer to that question.

If "soil type CA" did not come from a soil map, you will need to consult the source. There is no universally recognized soil type named "CA."

Tiny organisms such as worms help soil by giving off enzymes and hormones to help give the soil nutrients and water. Tiny organisms also help carry and spread water in the soil so that each plant gets its own share of nutrients. Also the insects that eat at dead things that start to decompose, those insects also carry nutrients into the soil so that way the soil becomes richer and healthy plants can grow healthier and faster.

Soil type "FeD" is the abbreviation for a soil map unit, and it is specific to the soil map/survey. That is, more than one soil survey might have labeled a map unit "FeD," and each soil survey might use that abbreviation to represent a completely different soil.

Look in the soil survey book where you found FeD. If you found this on the USDA's Web Soil Survey, the soil name should have been supplied in the legend.

If seeds are planted in dry soil, they may have difficulty germinating and establishing roots due to lack of moisture. Without adequate water, seeds may fail to sprout or germinate at all, leading to poor plant growth or even death. It is important to ensure that soil is adequately moist for successful seed germination and growth.

Urea, when applied in excessive amounts, can lead to a rapid increase in soil pH, creating a harsh alkaline environment that can harm soil organisms. The high levels of ammonia released during urea breakdown can be toxic to soil microorganisms, disrupting their normal activity and growth. This can inhibit the decomposition of organic matter and nutrient cycling processes in the soil, impacting its overall health and fertility.

Soil moisture utilisation refers to the ability of plants to access and use water stored in the soil for their growth and development. It is a crucial factor in determining plant health and productivity, as inadequate soil moisture can lead to water stress and hinder plant growth. Farmers often monitor and manage soil moisture levels to ensure optimal conditions for plant growth.

Clay soil generally has the lowest percolation rate, with an average rate of around 0.006 mm per second. This slow percolation rate is due to the tiny particle size and high density of clay soil, which restricts the movement of water through it.

Silty soil is better than sandy soil for plant growth because it has smaller particles that hold water and nutrients more effectively. This soil type also offers good drainage and aeration while retaining moisture, providing an ideal environment for root growth.

Water, air, nutrients, and organic matter filter through the soil. These substances move through the soil profile, facilitating plant growth and supporting various soil organisms. The composition and characteristics of the soil affect how well it filters and retains these substances.

The rate at which water flows or passes through soil is influenced by factors such as soil texture, structure, compaction, and hydraulic conductivity. Sandy soils typically allow water to flow more quickly compared to clay soils due to differences in pore size and connectivity. In general, soil with high permeability will allow water to flow faster than soil with low permeability.

Climate, silent and sanitary environment, and enough food for the worms are some critical factors that affect the cocoon formation.

The LBC (Liquid Limit, Plastic Limit, and Plasticity Index) of Jayankondam soil can vary based on its specific mineral composition. These properties are determined through laboratory testing, which involves measuring the moisture content at different stages of soil deformation. The results help to classify the soil and understand its engineering properties.

Herbs that prefer acidic soil include rosemary, parsley, thyme, and mint. These herbs thrive in soil with a pH level between 6.0 and 7.0. To maintain the acidity of the soil, you can amend it with peat moss or compost.
