After reading this article you will learn about:- 1. Definition of Soil Acidity 2. Source of Soil Acidity 3. Kinds 4. Problems 5. Amelioration. Definition of Soil Acidity: An acid is a substance that tends to give up protons (hydrogen ions) to some other substance. Conversely, a base in any substance that tends to accept protons (hydrogen ions). Soil acidity [...]
After reading this article you will learn about the influence of lime on soil properties in relation to plant nutrition. Direct Benefits: (i) Toxicity of aluminium and manganese is the most important growth limiting factor in many acid soils and this toxicity effect can be reduced by the application of liming materials. Besides this, the reduced uptake of calcium (Ca2+) [...]
After reading this article you will learn about the chemistry of hydrogen and aluminium in the development of soil acidity. It is evident that hydrogen and aluminium both contributes soil acidity. Hydrogen ions contribute soil acidity directly while aluminium ions do so indirectly through hydrolysis. Therefore, it is essential to know the chemistry of aluminium for the development of soil [...]
