Upload NowAfter reading this article you will learn about the sources of hydrogen ions for acid soil. Soil acidity is caused by ionisable hydrogen ions. Exchangeable hydrogen ions (which along with other such cations) are present in the soil to neutralize the negative charge arising from isomorphous substitution. They are displaceable by any cation which is […]

Short Notes on Acid Sulphate Soils
Article shared by :
This article provides short notes on acid sulphate soils. Acid sulphate soils are extremely acid soils. They have a pH which is less than 4.0 in some layer (in the upper 50 cm) of the profile. The acidity is due to presence of sulphuric acid and iron and aluminium sulphates. They are derived from marine […]
Development of Acid Soil: 5 Factors
Article shared by :
This article throws light upon the five main factors responsible for the development of acid soil. The factors are: 1. Leaching due to Heavy Rainfall 2. Microbiological Factors 3. Origin of Acid from Acid Parent Rock Material 4. Removal of Bases by Crops 5. Continuous Application of Acid-Forming Fertilizers. Factor # 1. Leaching due to […]
