Mean process accelerate chemical reactions in soil which has potential or availability will be acidic soil. ให้เปรี้ยว severe acid. Then improved by adding lime or alkali.A continent of his Majesty the king when B. ๒๕๒๗ to the experiment center for the study of political development. When results are then applied in acid sulfate soil, such asAcid sulfate soil and Nakhon Nayok, etc. the แกล้งดิน is to accelerate the chemical reaction with sulfur or compound soil mineral pyrite. (Pyrite) by making the soil dry and wet alternately. When the soil is dry, exposed to air.When the wet soil sulfate mixed with water to become acidic again. When the soil was pretending to switch into a sour or acidic soils, severe. Then, improve the soil by adding lime dust which is spotted.Field crops such as corn, fruits such as passion fruit and fish such as tilapia has
