เมื่อพูดถึง “ดิน” ทุกคนทราบดีว่ามัน

When talking about "Earth," everyone knows that it is a part of the land that we have trodden the objects we use planting or as the basis of a residential building, but it means the science on Earth (soil science). "Dirt" (soils) refers to natural thewatthu (natural body) caused by the disintegration of rocks and minerals. Mash mixture with a อินทรีย object, which covered the surface world is a thin layer that support the growth and use of plants. Separated layer (horizon) that can be observed from the steps to the bottom. The territory has its own identity and characteristics, which humans can be any kind of a separatist. The soil is composed of solid minerals, water and air objects อินทรีย with different proportions. The emergence of the Earth as a result from the action of various factors such as climate, plants, and other organisms toward the object the origin of Earth. In any one area. Over a period of time, so the "soil" in which one may be identical or different from the soil in one. Depending on the influence of these factors, which are much less different in each area, as a result, the soil is a factor, and when to change various properties of soil characteristics or are changed.The relationship of these factors can be written instead by the equation. When a particular type of soil = S Cl = climate P = innovation thun the origin of Earth. O = biological factors. R = terrain factors T = duration of continuous without interruption. Climate (climate) Climate influence the occurrence of soil or soil of different characteristics: temperature and rainfall, which both influence the rate of decay of the stones. Both physical and chemical aspects of mineral (physical and chemical weathering) can also influence the rate of speed of movement and accumulation of rocks and minerals that were to become the most important object is the origin of the Earth. Tropical rock minerals are decomposed into the soil faster than in the khetopun, or winter because of high temperatures and tropical rain quantity over winter. The different disintegration weathered ruins everything progresses rapidly. To wash a lot of nutrients to plants. It often causes soil fertility is low. Objects, the origin of the soil (parent material) As an important factor of soil birth control and visibility, and quite clearly influence the composition of the soil, such as color, soil texture. The structure and chemical properties of soil In General, the soil that is caused by an object that originated from their rock disintegration with the reaction is alkaline (basic rock) is often a dark color fabrics, soil fertility is high. Best soil caused by stones, they are the reaction is acid. (Acid rock) is often a rough texture soil dimmed. Fertility and the ability to Exchange low prachubuak etc. Geography (relief) In this case I mean pitch, or not the same level of State space and slope of the area related to the underground water level, these factors influence the occurrence of various layer styles. In the face of soil cutting The depth of soil color relative humidity in the soil and the severity of washing etc. For example, soil, resulting in a high slope is often shallow soil. There is minimal washing chandin's face is very thin on the ground or possibly chandin no chandin on much. Contrary to the Earth, resulting in the plains are often thicker than chandin since it is on the source of sediment. LP over details because the movement of soil from clay size particles layer on down to Earth on the bottom. Biological factors (organism) Include various creatures which consists of plants and animals, but often highlight the various plants which covered on the surface which influence. The quantity อินทรีย in soil and chemical composition of the soil. Clay was born under its plants at a pasture often have a อินทรีย object, and the elements that are plant food than Wild Coast forest or pine solid, etc. Time (time) The influence of time in terms of the range of the mean Earth times continued without serious incident interrupted the development of the Earth. When a particular type of ground zero for a point where one has a serious event to occur, the soil is treated as the end of time in the creation of the soil, and would be the beginning of a period of the next interval. Such a catastrophic event could mean changes in underground water level terrain changes to climate in the immediate or changes of soil origin object, such as an override of the radical new sludge Grill tamor, etc.

When it comes to "ground" Everyone knows where it is. Components of the earth I tread The object of our crops. Or as the basis of a residential building. However, the definition of scientific soil (soil science), the "ground" (soils) represents the natural objects (natural body) caused by the decomposition of rocks and minerals. Mixed with the soil surface, which is covered in a thin layer. The object of sustained growth and stability of the plant. The stratification (horizon) that can be seen from the top to the bottom. The territory and the identity of its own. The man can differentiate into different types of soil. The soil consists of solid minerals, organic matter, water and air, the proportion varies widely. The emergence of the soil as a consequence of the joint action of various factors such as climate, plants and other organisms on the origin of the soil. In one of the areas Over a period of time so the "ground" in one place, it can be the same or different from one another in the soil. Based on the influence of these factors. This is very different in each area, the soil is characterized. And when the change Clay looks or performs. Change the relationship of various factors. These can be written as an equation on S = soil type, cl = Climate p = object is the origin of the earth, o = biological factors r = factors terrain t = time continuously without interruption. Climate (Climate) climate that influence the occurrence of soil or soil with different characteristics such as temperature and rainfall, both of which have an influence on the rate of decay of rocks, minerals, both in the physical and chemical properties (. physical and chemical weathering) also influence the rate of migration and accumulation of rocks and minerals that is transformed by the ringleaders. As the origin of the mineral soil in tropical soil is degraded faster in warm or cold climates due to high temperatures in the tropics. And the amount of rain that winter. Decay and dissolution It progresses rapidly Leaching of plant nutrients out a lot. It often leads to low soil fertility, soil parent materials (parent material) are important factors controlling soil. And seen quite clearly as possible. And influence the composition of the soil, such as color, texture, soil structure and chemical properties of the soil. In general, soil degradation caused by the origin of the rock they are alkaline (basic rock) is often a fine, dark soil of high fertility. The soil formed from rocks that are acidic (acid rock) is often coarse soil fertility dimmed. And low cation exchange capacity. And terrain (Relief) , referring to a lower altitude. Or unequal conditions of space. And the slope of the areas related to groundwater levels. These factors influence the appearance of floors in soil depth, soil moisture, soil color. And severity of soil erosion, etc. For example, resulting in a high slope. Usually a shallow soil There are a few ground floor Wash the soil The upper soil layer is thin Or maybe not at all on the ground floor. In contrast to soil formed in the plains. Always has the upper soil layer thicker because of the deposition of sediments. Finely ground beef Because the movement of clay topsoil to accumulate in the soil biological factors. (Organism) include various organisms. Consisting of plants and animals I always focus on the flora and fauna. That cover the surface Which influence The organic matter in the soil And chemical composition of the soil The soil under the grass plantings. Often with organic matter and minerals are nutrients than soil of pine or hardwood forests and time (time) the influence of time in terms of the soil means a certain period of time, continued without incident. severely interrupted the development of soil. Time zero for the soil type, it is the one that has had a serious incident occurring soil. It is the end of time in soil formation. And will be the beginning of a period of soil formation follow. Such violence may mean. The terrain changes Groundwater levels In abrupt climate change or changes in soil as a severe deposition of sediments etc.

When talking about the "soil", everyone knows it is a component of the earth, we stepped on. An object, we use the plant. Or is the basis of residential buildings. But the meaning in Soil Science (Soil Science)

."Soil" (soils) means the natural body (natural body) resulting from the decomposition of rocks and minerals. Mixed with organic matter, which covered the skin. The world is a thin layer The object that upholds the growth and balance of plant.(horizon) that can be noticed from upper to lower. The territory and the identity of its own. Which man can be divided into different kinds of soil,
.
.The soil consists of minerals of solid organic matter, water and air with different proportion The emergence of the soil as a result due to the action of mutual factors such as climate, plants, and other creatures.In any one area. During the period of the "soil" in one place and thus may like or different from soil in another place. Based on the influence of these factors.And when the change. Soil features or properties change with
.
the relationship of various factors These can be represented by the equation



= when S soil type on CL = climate
P = object tree birth of soil biological factors o =

. R = the terrain
.T = continuous time without interrupting the climate (climate)

.The climate affected the soil or soil with different styles, such as temperature and rainfall, which are both influencing the rate of dissolution of stones. Ore, both in the physical and chemical (physical and chemical.Both also influence the speed of moving and the accumulation of new rock and mineral was transformed by the kingpin. As the parent material of soil in tropical, rocks, ore is decomposed soil is faster than in warm region or the winter.In the tropics, high temperature and rainfall of over the winter. Weathering, thus speeding up, the plant nutrient leaching out a lot. It often makes soil fertility low
.
the object the origins of soil (parent material)
.A control factor soil formation that matters. And seen quite obvious. And the influence of soil elements, such as colors, soil texture, structure and chemical properties of soil(basic rock) is often the soil texture, high fertility, dusky The soil is made from stone containing acid reaction (acid rock) is often the soil coarse faded, abundance, and the ability to share positive charge is low. Etc.
.
terrain (relief)
.Here means the height. Or at a different level of the area. And the slope relating to the water table. These factors affected the layers in the soil, the depth of the cut face ground color.And the severity of the erosion, etc. for example, soils in the high slope, usually a shallow soils with low soil with soil erosion. Soil on to some, or no soil on it.Often have soil on thicker due to accumulation of sediment sources of soil texture detail. Because of the moving particle size of clay from the top soil to accumulate in the soil below
.Biological factors (organism)

.The various creatures, which consists of plants and animals. But often focused on the vegetation covered up on the ground surface, which influence the quantity of organic matter in soil and chemical composition of the soil.Often have organic matter and trace elements that are food plants rather than soil or solid pine forest, etc.!Time (time)

.The influence of time in terms of soil formation that refers to a certain period of time contiguous without violent incidents interrupt the development of soil. Time is a kind of earth is for.Considered to be the end of time in the creation of soil. And will be the beginning of the period in the creation of the soil during the next. Such extreme events might mean. Changes in topography, ground water levelOr a change of soil parent materials, such as with the accumulation of sediment new severely, etc.
