The benefits of the Earth.The soil is very useful mayomhasan people and other living organisms.1. the benefits to agriculture because land is a agriculture originated as a human food source. On the ground, there will be a อินทรีย object and nutrients as well as water, which is essential for the growth of plants. The food that we consume today comes from agriculture reaching 90%.2. the animals The ground is home to both their crops and forage grass that is based as well as certain types of animals, such as insects, snakes etc., Otter.3. residential land is the source of the city. House of culture and civilization that are causing many of the community.4. is the catchment of the major components of soil texture, there is a sludge-Sand Pebbles, including solid and liquid is water, which is in the form of humidity in the soil, which is very much, if any, will become the water underground water. These will be gradually absorbed into the water below, such as rivers, canals, we have water available throughout the year.The type of soil.Particles of dirt are assembled into a clay tablet. These particles are not equal. The smallest is the clay particles. Medium size particles particles, sand, flour, large particles called called the sand particles are particles of soil texture, all mixed together in groups of 3, this not the same proportions, causing the appearance of large type 3 is a clay soil. Soil, sand, and clay ruan1. clay is a soil when wet and the flexibility may serve as a statue or a long stick noena a sticky soil drainage and bad weather. Has the ability to absorb water. With the ability to handle and plant nutrient Exchange has high or fairly high soil particles lump in detail, because it has a clay. Suitable to be used for rice farming, since water storage for a long time.2. the soil is sandy soil with good drainage and air. Has the ability to absorb water, low. Have low fertility because of their ability to catch the rare plant based nutrients? The upper sand plants often lack food and water the soil with sand, soil texture, because a lot of sand particles.3. soil is a soil texture soil ruan is quite soft, flexible fingers details? There is good drainage, moderate. Soil texture is suitable for cultivation, it is often rare in nature but is found the soil with closest together, rather than ground meat.The color of the Earth. The color of the Earth, to make us aware of the abundance of quantity อินทรีย objects that mingle and turn into a hiomat in the ground. Make the color of the soil, there are different color will fade a little hiomat there are plenty of less.The problem of soil resources.Most of the soil is destroyed, the loss of soil fertility, or the beef because of human actions and the loss of natural causes, we could not take advantage of the full power, Soil loss caused by1. erosion and erosion by water. Many of the affected surface water directly to the soil surface erosion, dropped to the water. The loss of surface area, it is regarded as a space or a small Groove, depending on the strength and water runoff areas down.2. the deforestation Burning of the forest and forest land open to mow and water wash it and when the rain fall. Water wash to remove soil fertility to face with water quality soil decay.3. preparing the soil and planting method. Land preparation and planting if done correctly, it creates a lot of damage to the soil, for example, to loosen soil plough the soil dry, while at float with the wind dropped completely or to some types of crops to make the ground deteriorate quickly. Burning of forests or rice in it to make hiomat in soil decay caused more damage to the results.Soil conservationThe problems caused by erosion or loss of soil fertility, it would cause other problems, such as lack of land followed rich farmers to buy fertilizer, chemicals, maintenance free ground chayomhasan comes. Sludge soil is washing make the rivers and shallow river mouth. Need a lot of money to dredge used, we should prevent soil erosion or degradation, which can be performed by soil conservation.1. land use properly fitting Plants should be, regardless of the type of plants that suit the properties of the soil. Cropping and plough to loosen the level to prevent erosion of soil washing. In addition, it should reserve the land with fertility treatment is used in other ventures, such as industrial housing because there is abundance and land suitable for cultivation, there is less.2. maintenance of soil to add updates to make the soil nutrients such as manure, fertilizer, worked to put the plants in kata-Gu lathua. To put the lime in the soil is acid. Salted soil area of editing by drainage, land access, etc.3. the prevention of soil degradation, including planting ground covers. Crop rotation Cropping shield to loosen the plough wind levels. Making a page khandin protecting the flow quench all the flaming forest or non-slash.4. the soil is sufficiently moist. To drain the water present in the soil off the ship into land and consumption, such as grass or straw veil the land would allow soil fertility is.
