After reading this article you will learn about the buffering of soils. Buffering of soils is their resistance against any change in the concentration of hydrogen or other cation in the soil solution. For example, the clay micelle is almost completely saturated with hydrogen ions in strongly acid soils which also contain some in the soil solution. The hydrogen ions [...]

Characteristics of Salt Affected Soils: The most important characteristics of salt affected soils like saline, non-saline-alkali, saline-alkali and degraded alkali soils are given in table 15.2. Formation of Salt Affected Soils: Saline Soil: The process by [...]
This article throws light upon the top three methods used for reclamation of saline and alkali soils. The methods are: 1. Eradication 2. Conversion 3. Other Methods (Salt Precipitation Theory). Method # 1. Eradication: The most common methods generally used to saline soils are: (i) Under drainage and (ii) Leaching or flushing. A combination of the two, flooding after tile [...]
