It's too cold for organic content to survive in Antarctica.
What else can I help you with?
What type of soil does antarctica have?
Antarctica's soil is primarily composed of gravel, sand, silt, and clay, with limited organic matter content. The extreme cold temperatures and limited precipitation in Antarctica make soil formation slow, and most areas are covered by ice with little exposed soil.
The use of organic manure vs the effects on the soil?
increases the soil humus content soil microbs helps in soil maintenance
Why top soil has high organic matter than subsoil?
Topsoil has higher organic matter content than subsoil because it is constantly receiving organic inputs from decomposing plants, roots, and organisms at the surface. These organic materials break down and add nutrients to the soil, increasing organic matter content. In contrast, subsoil layers are less exposed to these organic inputs and therefore have lower organic matter content.
What kind of soil goes best with most cacti?
Sandy soil without water logging and good drainage, with low organic content goes best with cacti. Sandy soil without water logging and good drainage, with low organic content goes best with cacti. Sandy soil without water logging and good drainage, with low organic content goes best with cacti.
What is sub soil made of?
it is made of decomposed organic matter and and mineral content.
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.
Does herbicides affect soil fertility?
If used properly, herbicides don't directly affect soil fertility. What effect they may have is in the gradual reduction of soil organic matter content. As the soil is no longer getting the same amount of plant residue deposited in it, the organic matter content can be slowly reduced.
What is the general pattern of distribution of organic matter in typical soil profile?
In a typical soil profile, organic matter content tends to decrease with depth. The highest concentration of organic matter is usually found in the topsoil layer, known as the A horizon. As you move deeper into the soil profile, the organic matter content decreases because of decomposition and mixing with mineral particles.
Explain the origin of organic matter in soil what does organic matter do to soil?
Organic matter in soil comes from decomposed plant and animal material. It enriches the soil by improving its structure, moisture retention, and nutrient content. Organic matter also supports beneficial microbial activity, which enhances soil fertility and overall plant health.
Why do humus tend to increase with the clay content of soil?
As the clay content increases, there is more surface area in the soil for organic matter to adsorb to, which decreases the rate of decomposition.
What gives soil color?
Soil color is primarily determined by its mineral content and organic matter. For example, the presence of iron can give soil a red or yellow color, while high organic matter content can make soil darker in color. Soil color can also be influenced by environmental factors such as moisture and drainage levels.
What causes soils to vary in color?
Leaving aside the obvious (wet soil looks darker), the amount of organic matter or humus in a soil controls how dark the soil is. Generally the darker a soil is, the "richer" it is considered to be.
