Acid sulfate soils or acid soils (Acid soil) means soils with a pH lower than 7.0 is not so soils (Acid sulfate soil) is a type of acid soils or soils. But there are significant differences from conventional acid or acid soils generally. Book coined word Geography Academy of Letters (2523) has meant that the acid sulfate soil is acid or acid soils mean sulfur soils. It is the soil, causing enormous problems in the economy and society of the country. Since the soils are spread everywhere in the country. The central plains south. Southeast coast and the east coast of the South. Soils mostly flat marsh throughout the rainy season and the nature of the soil is clay, it is used as arable crops. The cause of these areas, the low grain yield. Although the terrain is generally appropriate to do it. But compared to the non soils, which would yield an average over several times. The modified soils, so it is to be carried out urgently and continuously considering the problems of the soils found that acidity severely soil is a major cause of plant growth and productivity. Plants slump Because the nutrient availability of the plants has decreased or no longer sufficient to meet the needs of the plant. Plant nutrients that are low in nitrogen, phosphorus, the nutrient of some plants are more than needed, which would cause harm to the growing technology and productivity of crops such as aluminum, iron, manganese and the. The acid also affects the activity of microbes that live in soil and plants are beneficial to lower volumes. Therefore, it is necessary to find appropriate ways to solve the problem soils to increase crop yields to rise. This economic and social problems. As well as to solve problems using the earth's resources for the benefit and cost. Effective And sustainable type of acid sulfate soils, acid soils are acidic properties because of agricultural issues, which affect the growth of plants and affect the volume of agricultural products. Found that acid soils are characteristic of the soil and the soil can classify soils have three types of soils acid or very acid soil sulfur (Acid sulfate soil) soils acid or very acid soil sulfur (Acid sulfate soil), the ground was caused. The settling of the sea, brackish water or sediment. The compounds of sulfur, which is converted into sulfuric acid, the natural process accumulated in thick layers of soil cut by a soil with high acidity. Low fertility Lack of nutrients essential to plant growth severely. Such as phosphorus deficiency I also have some kind of nutrient nitrogen than necessary, which can result in serious or harmful to the growth of plants such as iron, aluminum, etc., organic soil. Or generally known "Peat" in the soil as organic soils are dense spread along the border or the border of Thailand and Malaysia, as most also found generally in the south and east of the country. The area is peatland areas or areas that organic soils. By nature it is a basin with water throughout the year, which is caused by the deposition of various plants to rot eroding the layer thickness from 40 cm to a thickness of about 10 meters has degraded slowly making organic acids being. released collection is constantly ongoing. This soil has a low amount of clay. And potassium and secondary nutrients needed by the plant is less soil types are found in the coastal plains soils are present in the lower layers of soil. If the drainage from the area until the peat soils of the potential to cause new problems as it is to emerge as a more acid soil sulfur. Made redundant as a problem soils and organic soils. This will result in improved cost more up acid soils. Or conventional acid or acid soil made plain. The soil is very old, which is commonly found. Acid soils occur in the area of tropical rain. Soil through leaching or soil that has been used for a long time. Which makes the soil with low fertility, clay and organic June day is washed away with a result fertility in general. Low to very low to the ground. The soil also has the ability to absorb water with low birth process acid sulfate soils process. The process includes a process is known as the origin of soils, soil, geological processes (geogenetic process) and a process known as acid sulfate layer. The process of creating the clay soil (pedogenetic process) which processes the stem soils are associated with the compound Prime Wright (pyrite) or sulfide compounds. But the process of acid sulfate layer would involve oxidizing substance Prime Wright, then a compound of sulfuric acid.
