How long does it take before grasslands are formed?
447973
Grasslands are formed within a year.  After a fire or clear cutting, grasslands pop up really quick because they have sun and do not require much water.

it takes about as long as the 100 year war!!!

Usually 3 days, but it could even be longer then that depending on where you are exposed and how often.

Holocene Soil Development on Till and Outwash Inferred from Lake-Sediment Geochemistry in Michigan and Wisconsin \nAuthors: Ewing H.A.1; Nater E.A.2\nSource: Quaternary Research, Volume 57, Number 2, March 2002, pp. 234-243(10)\n\nParent material. Few soils weather directly from the underlying rocks. These "residual" soils have the same general chemistry as the original rocks. More commonly, soils form in materials that have moved in from elsewhere. Materials may have moved many miles or only a few feet. Windblown "loess" is common in the Midwest. It buries "glacial till" in many areas. Glacial till is material ground up and moved by a glacier. The material in which soils form is called "parent material." In the lower part of the soils, these materials may be relatively unchanged from when they were deposited by moving water, ice, or wind.\n\nSediments along rivers have different textures, depending on whether the stream moves quickly or slowly. Fast-moving water leaves gravel, rocks, and sand. Slow-moving water and lakes leave fine textured material (clay and silt) when sediments in the water settle out.\n\nClimate. Soils vary, depending on the climate. Temperature and moisture amounts cause different patterns of weathering and leaching. Wind redistributes sand and other particles especially in arid regions. The amount, intensity, timing, and kind of precipitation influence soil formation. Seasonal and daily changes in temperature affect moisture effectiveness, biological activity, rates of chemical reactions, and kinds of vegetation.\n\nTopography. Slope and aspect affect the moisture and temperature of soil. Steep slopes facing the sun are warmer, just like the south-facing side of a house. Steep soils may be eroded and lose their topsoil as they form. Thus, they may be thinner than the more nearly level soils that receive deposits from areas upslope. Deeper, darker colored soils may be expected on the bottom land.\n\nBiological factors. Plants, animals, micro-organisms, and humans affect soil formation. Animals and micro-organisms mix soils and form burrows and pores. Plant roots open channels in the soils. Different types of roots have different effects on soils. Grass roots are "fibrous" near the soil surface and easily decompose, adding organic matter. Taproots open pathways through dense layers. Micro-organisms affect chemical exchanges between roots and soil. Humans can mix the soil so extensively that the soil material is again considered parent material.\n\nThe native vegetation depends on climate, topography, and biological factors plus many soil factors such as soil density, depth, chemistry, temperature, and moisture. Leaves from plants fall to the surface and decompose on the soil. Organisms decompose these leaves and mix them with the upper part of the soil. Trees and shrubs have large roots that may grow to considerable depths.\n\nTime. Time for all these factors to interact with the soil is also a factor. Over time, soils exhibit features that reflect the other forming factors. Soil formation processes are continuous. Recently deposited material, such as the deposition from a flood, exhibits no features from soil development activities. The previous soil surface and underlying horizons become buried. The time clock resets for these soils. Terraces above the active floodplain, while genetically similar to the floodplain, are older land surfaces and exhibit more development features.\n\nThese soil forming factors continue to affect soils even on "stable" landscapes. Materials are deposited on their surface, and materials are blown or washed away from the surface. Additions, removals, and alterations are slow or rapid, depending on climate, landscape position, and biological activity.\n\nWhen mapping soils, a soil scientist looks for areas with similar soil-forming factors to find similar soils. The colors, texture, structure, and other properties are d

That depends entirely on the species of tree, where it is growing and what you want to use it for.\n\nMany tropical and subtropical hardwoods such as Pinus radiata are capable of growing to usable size within 10 years. Other species may take as much as 100 years.

I have found 1 to 2 weeks before rut begins, and then only "tickle" the antlers. I would only rattle loudly during the actual rut. Contact a state biologist to determine the rut in your area!

it will probably take a day or two\nthank you

I assume you mean for bovines. Cattle. Moo. \n\nIt is approximately 281 - 284 days. That is approximately 9 and a half months give or take.\n\nIt depends on the breed of cattle, sex and weight of the calf, parity and breeding season (PIEDRAFITA, Jesús; et al.; pp. 354, http://www.edpsciences.org/articles/animres/pdf/2000/04/z0406.pdf?access=ok)\n\nHere are some links with charts of gestation periods for various mammals including cattle -

The way it is treated will affect its life. Should you place the stem in a polystyrene cube, floating in a tank of aerated water, stocked with nutrients and maintained at 26 degrees celsius, you would begin generating a healthy "clone" of the original plant within three weeks.

Some things just take time to develop

I very much doubt that it will be finished as early as 2007 ... there are still a lot of volumes to go ... at least 13 ... and they have only published 11 since 1994. Grasses are due out soon, though. At that rate, it will take another 12 or so years ...

Stop rushing around.  Stand still for just one minute and look at the flowers and grass.  You'll be amazed how quiet it can be.

Not very long. The north was far more industrialized the the agrarian south. What the person above said is true as well.

well buddy it takes around 4 weeks for the results to be declared. be patient. you can check out on sofworld.org.
