Acidic soilThe soil sour or acid (Acid soil) soil means soil that has a pH of less than 7.0, so the soil sour (Acid sulfate soil) is a type of acid or acidic clay soil, but soil is different from the General acid or acid soil plain. Book a Royal Institute of geographic words (2523 (1980)), acid sulfate soil means that soil acid soil means sour and acid soil sulfur. Clay soil is considered to be sour, causing problems for the country's economic and social system. Because most of the land area, the entire scene in General in all the country. The Central Plains, especially the southern coastal area of the South-East and the East coast of the southern land mostly sour, there are Plains during the rainy season the water trapped and the nature of the soil is clay, so rice planting is held. That is a major reason that makes the area so low rice yield. Although the terrain is generally appropriate to do, when compared to the area of land which is not sour, which is more than average yields. Therefore, to improve the soil sour, it is something that must be carried out urgently and consistently. When you consider the barriers of Earth, acid, sour found that official version of Earth as a major reason that causes plant growth and yield of crop decline. Because, as the main benefits of the nutrient or plant is not sufficient to the needs of the plants. Nutrients of plants are nitrogen, phosphorus, low level is best, there are some kinds of plant nutrients than necessary, which can cause hazard to the growth and yield of no cultivated, such as aluminum, iron, manganese, and acid held to affect the activity of the Jung Li tree.Put live in soil and plant with benefits reduced. Therefore, it is necessary to find an appropriate way to solve both problems, the soil sour to increase output quantity. That is economic and social solutions as well as solutions to the land resources efficiently. Efficiency and sustainability further. The type of the soil acidic The soil is acid soil agricultural problems because the acid properties that affect crop growth process and can affect the quantity of agricultural produce. That is the nature of acid soil and the soil occurs, the process can break the types of soil have 3 categories as follows: Soil or clay soil, acid, sour sulfuric acid arrangement (Acid sulfate soil). Soil or clay soil, acid, sour sulfuric acid arrangement (Acid sulfate soil) as t from settling of the brackish water, sea water, or sediments that contain compounds of sulfur, which is converted to sulfuric acid as a natural process, accumulated in the soil by cutting the face layer is clay with a high-acid. Low fertility lack nutrients necessary for plant growth, such as the lack of a serious element phosphorus. Nitrogen are some nutrients than necessary, which results in fatal or harmful to plant growth such as iron. Aluminium, etc. Organic soil or generally referred to as "swamp soil." In countries with organic soil, soil is a dense spreading lies along the border or the border Thailand and Malaysia are also found most common in the South, and by the East of the country. The area is the area of peat soil area, organic. It is natural that the basin with water trapped all year round, which is due to the deposit of decayed plants that generally ranges from 40 cm thick layer break down to approximately 10 m thick Miami decay slowly, making organic acid is accumulated is discharged continuously all the time.Due to d This type of soil is clay with low volume and a primary and secondary nutrients nutrients that are necessary for this type of soil, the plants are less common in the Plains along the sea to have sour soil on the ground floor. If it has been drained from the area, peat soil level, the sour, the new issue will be what is sulfuric acid. Make duplicate issues, both organic and sour soil, which makes it costly to update other amendments. Soil acid or acid soil plain The soil is clay or soil, acid regurgitation, very plain, old age, which is found in General. Soil acid rain areas occurred with rain Earth through a wash, or soil that is useful for a long time, which makes the soil with low fertility because of the clay and organic day thu, was there along with washing the fertility of the soil by typical low very low compression. In addition, the ground also has the ability to absorb water is low. The process caused the soil sour The process caused the soil sour contains the major process is the process of originating stem soil sour or object called Earth geological processes (process geogenetic) and the process of birth, chandin sour or through the process of creating a land called potphiwitya (pedogenetic process), the process of originating stem soil sour object is associated with the occurrence of compounds or membranes (pyrite), sulfide compounds Wright, but the process of birth, chandin sour will involve oxidized fiber additives, a compound of acid Wright sulfur.
