Study on Relationship among the Various Physico-Chemical Soil Properties and Identification of Soil Acidifying Components

Soil acidity is one of the major obstacles to crop growth to a great extent. IN different districts of West Bengal, soil acidity has been reported as a considerable factor behind crop growth restriction. Hence, a comprehensive study has been conducted with a view to study the relationship among the various forms of soil acidity and other physico-chemical soil properties, covering Godkhali, Coochbehar and Purulia under investigation. Outcomes of the investigation clearly reveal that all the physico-chemical properties has been found to have significant influence on different forms of acidity. Along with this, it can be also inferred that among the forms of different soil acidity, for all the forms, significant positive linear association has been observed. It has been also obtained that hydrolytic acidity, extractable acidity and pH-dependent acidity can be considered as the most vital soil acidifying component.
