King"s royal visit people in Narathiwat Province in 2002. 2524 ทรงพบ that after induction water from peat swamp area in order to have the area.
Agriculture is used and flood mitigation. Showed that the soil in the area is transformed into a swamp of acid sulfate soil, crop, ineffective, so there is a royal counsel to various government agencies.
Consider find ways to improve the area with water soaked in peat utilization in the year of เกษตรมา as possible and to impact on the ecosystem. Metamorphism
An acid sulfate soils Because the soil is a litter decomposing organic waste material or above the level 1-2 meters depth soil is Iain gray and blue. The sulfur compounds called compound pyrite (pyrite: FeS2), so when the soil is dry and pyrite reacted with air release of sulfuric acid. Make the soil into soil acidity or sour Center for the study of political resulting from the Royal and the Royal แกล้งดิน meet project. ""
To study the changes in acidity of the soil, starting from how to "แกล้งดิน sour." compared to the soil dry and wet times. To accelerate chemical reactions of the soil, which will go.
Encourage of pyrite react with oxygen in the air, releasing the sulfuric acid, the acid soil till a step. "แกล้งดิน sour" until the point of extreme plants.
Can"t grow. Then find out how to improve soils to crops. A method to solve the problem of acid sulfate soil works are as follows.
1. Control ground water level To prevent the sulfuric acid. The need to control the groundwater over soil Lane containing pyrite. To prevent of pyrite react with oxygen or oxidized.
2. Soil improvement with 3 method. According to the condition of the soil and suitable.
Water leaching acidity. When washing acid to release and soil is the pH increased both iron and dilute solution อลูมินั่มที่ poisoning that plants can grow well. Especially if you find.
