Soil

Parent Category: Geology
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.
because phosphate rocks contains various metals and radionuclides  as minor constituents of ores.
ya it may be possible that by the using role scoper results in soil  erosion
This is due to different soil compositions.
It helps the soil hold more rainfall so there will be less runoff and ruin the crops.
Infertile soils lack abundant plant nutrients, especially for  agricultural crops. It doesn't mean they're unsuitable for plant  growth, but the only plants that naturally grow on them are those  that can either do with few nutrients, or can get their nutrients  from pools that are unavailable...
Cotton does not produce well in soil of high organic matter. A  lighter sandier soil is better for cotton. Cotton can also  withstand high temperatures and loves full sunlight during its  growing season. Cotton is grown on different types of soils, such  as sandy loam, clay loam, black cotton...
Yes, trees are good for the soil
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.
At one atmoshere pressure, water boils at 212 degrees fahrenheit, or 100 degrees celsius, theoretically you could heat a soil sample higher than that. It depends on the heat source. If you are speaking of temperatures found in nature, lava or magma is hotter than water, but can contain water vapor...

silt and alluvilium
Impatiens, Hydrangea, sunflowers and peonies are the plants which  needed a neutral pH soil.
it is not yet certain, due to many factors.    given how often land in organic matter.?   more often and with much volume, the soil will be quickly  recovered.    how often a given soil biological fertilizer.?   the contaminated soil will make positive bacteria will die and the ...
acidic soil limits the availabilty of major nutrient Nitrogen. Acidic soil causes Nitrogen to held in solid form NH4+ so it is unavailable to the plant. Plants need Nitrogen in solution which is NO3-
The ancient Romans who summered in magnificent villas overlookingthe gorgeous Bay of Naples accrued their riches by controllingtrade and taxes throughout the vast empire. Their wealth allowed them to indulge their appetites for the finestservants, chefs, and resident philosophers, food and wine,...
If the soil is hot heat rises and the air near and around the soil will rise to affect the other particiles of air.
It just does, OK?
  Is is the loss of soil by wind, or water. It can wash or blown away in gulleys or small ditches or it can be sheet where a wide spread area is removed. Sheet erosion is the one that is hardest to see
The roots of trees are of primary importance in preventing soil erosion, because they physically hold the soil in place, and also because they transport water up from the ground, thus supporting other plants and preventing salinisation of the soil. The leaf canopies are also important for soil...
  Soil takes a long time to build up, and without it, many plants cannot survive. Without plants, there can be very few insects or other animals that can live there.
by not using much fertilizers
In Strip Cropping, grass and other plants that grow close to the ground are planted in strips between bands of grain crops.
Wind erosion damages land and natural vegetation by removing soil  from one place and depositing it in another. It causes soil loss,  dryness and deterioration of soil structure. Water erosion is also  another factor.
mountain soil is earth that is rich in moisture, and it's texture ranges from rocky to sandy.
black soil generally is the best, but if you want yellow soil you could always kill a grub and squeeze the juice out. Good luck!
it is used to measure the temperature of the soil
The denudation of the soil cover and subsequent washing down is described as soil erosion. The processes of soil formation and erosion, go on simultaneously and generally there is a balance between the two. Sometimes, this balance is disturbed due to human activities like deforestation, over-grazing...
Yes. Growing plants is what potting soil is for.
Yes because the soil would be too sandy or wet. Plants need the right amount of soil depending on the type of plant. Too much soil can also cause the plant to "puke" or in other word "not feel good". This means plants will not get as much sunlight as needed because you have to almost double the...
Because of the moisture retaining properties of the humus content.
the uppermost layer of soil is loose.when wind blows , it can carry away topsoil.when rain falls and water flows on the land, much topsoil is carried away.erosion by wind water removes much of topsoil.
Liverwort's and Hornwort's would be found in very damp soil.
In a simple explanation, I think its because the roots act like a netting holding the soil in place.
 Accidental spills and leaks during storage,  transport or use of chemicals and diesel at gas stations);  Foundry activities and manufacturing processes  that involve furnaces or other processes resulting in possible  dispersion of contaminants in environment;  Mining activities involving...
In the uppermost six inches of soil is where most organic material is found. That's also where many plant roots are located. It's precisely because of the nearness to the surface and the availability of air, moisture, and nutrients that many roots tend to be located in those upper six inches. So...
Tundra soil has no commercial purpose whatsoever. In the winter it is frozn and in summer is squishy and water logged. Travel across tundra in the summer can be difficult.
  Plants make nutrients and collect water from the soil
  === hello ===     because it need minerals 2 shake its booty     and we need plants for oxygen and plants need minirals to grow  
It paid farmers to plant crops that protected the soil.
Sandy soil can be different colors, since there are different  colors of both soil and sand. One kind is pink with a light  brownish green look. Others are a mixture of yellows and tans.  Others are lighter sands: off-white interspersed with dark and  colorful specks. Others are kind of a bland...
the slope of the land contribute to soil erosion by eroding it
Soil, the loose material that covers the land surfaces of Earth and supports the growth of plants. Soil actually constitutes a living system, combining with air, water, and sunlight to sustain plant life. The essential process of photosynthesis, in which plants convert sunlight into energy, depends...
cause there is to much soil on the earth so there is eroison
Animals fertilize the soil by depositing their waste onto the soil. Furthermore, dead animals contribute to the soil structure by their decomposed body becoming one with the soil.
They help prevent soil erosion
  No earth and Mars both have dirt.
Heavy rain washed off the nutrients from the rainforest's soil.
sand is light and easy to dig
It blocks the erosion from happening. That is why it prevents/reduces the effects of erosion
well i dont know cause im the person that asked it tee hee hee
dumping of wastes in many areas
  == A mixture of sediments from weathered rocks,decayed material from organism,gases from air,and water. ==   == ==
It would probably die as it is an alien environment.
the plants that grow best in clay soil are plants that don't need much water because the clay will make it dry.
All plants grow well in garden soil.
  Many plants can grow in garden soil. Actually, ALL plants can grow in garden soil as long as you take care of them.
The organic molecules and some inorganic molecules in dirt are able to dissolve in water. But, minerals can't dissolve in water. So, only part of dirt is soluble in water.
In Jericho situated in the lower Jordan valley.
  Rocks are denser than dirt, and dirt is denser than water
The types of soils in different states of India, can include  alluvial, black, red, laterite, mountainous, desert, saline and  peat soils. The most common type of soil in India is alluvial.
Based on the spelling, I'm guessing you'd like to know about thehumus that's present in soil. If not, typing in "What ishummus?" in the white bar at the top of the webpage will giveyou the answer you're looking for! Humus can be defined as the organic layers that are abovethe mineral soil...
because of more organic material mixed in garden soil which absorb and hold water as compare to road side soil.
You can but you shouldn't. This can aide in bacteria growth and cause the potatoes to rot. On the other hand planting in moist soil should be fine.
Iron oxide, commonly known as rust, gives Mars it's color.
Most soil conditioners are mixed with water and watered into your garden soil. They can be applied multiple times during the growing season. Jungle Flora is an organic soil conditioner that also works as a plant accelerator.
Soil conditioners regenerate soil that has not been mistreated by chemicals or other misuses. Jungle Flora is a very good organic soil conditioner that adds essential components back into the soil, which in turn help your plants to grow much better and produce better harvests.
There are several different insects that are especially harmful to  cotton. Some of these are the boll weevil, cotton leafworm, cotton  fleahopper, and southern green stinkbug.
  # yes plant grow faster with water and soil because some plants are made to grow in homes/indoor.  # so if a plant in made to be inside a house it does not need sunlight to survise.   # yes plant grow faster with water and soil because some plants are made to grow in homes/indoor.  # so...
The A horizon as it consists of mainly organic matter.
Soil with loose pores will allow water to collect and roots to expand. Loose soil is therefore better than hard compact soil. On the other hand, finer particles, like clay increase surface area of the soil which will allow nutrients to stay in the soil. Very porous soil, such as sand, will allow...
The soil has to have lots of nutrients. It has to have neutral pH.I had this question for my science homework one night and that is what I got as an answer. I do not know if it is correct, so I'm warning you now so you don't blame me for the wrong answer (if it is wrong).
Both arctic and desert soils are generally quite thin. Also,neither soil has much organic material so consist primarily of rockparticles.
Microbiota (microorganism in the soil) help to fix nitrogen and  improve the absorption of other vital nutrients for plants. Besides  maintaining proper pH, etc., this is one of the main reasons why it  is necessary to keep the soil when transplanting one plant to  another area. Without the...
  that would be clay soil.. if you have any question contact me (grigoriy13@hotmail.com)
Soil Layers   The layers of soil are: Top Soil Sub Soil Parent Material bedrock
Generally, most plans grow roots in the top 12 inches of the soil, e.g. the topsoil layer is the most important
  it is clay soil because frist it is topsoil then clay soil and after that it is sand soil
