Acidic
soils in India are mainly prevalent in the humid Southwestern, Northeastern and Himalayan regions (Maji
et al. 2008). They are particularly acute in the humid tropical regions that have been subjected to severe
weathering. In India, about 48 m ha out of 142 m ha of arable land are affected by acidity, of which 25
m ha have pH below 5.5 and 23 m ha have pH between 5.6 and 6.5 (Mandal 1997). Strongly acidic and
moderately acidic soils cover 6.24 m ha (1.9%) and 24.41 m ha (7.4%), respectively of the country’s total
geographic area (Maji et al. 2012). In the Northeastern region, approximately 95% of the soils are acidic
and nearly 65% have strong acidity with pH below 5.5 (Sharma and Singh 2002). Acidic soils of Odisha
account for 70% of its total geographical area (Jena 2008). A similar finding was reported in Odisha by
Nanda et al. (2008) based on the analyses of 1,219,000 soil samples. A recent study conducted by ICRISAT
found that of the 40,265 soil samples analysed, more than 80% were acidic in nature","2020","published",,,,,"ICRISAT","Hyderabad, India","1-55","55",,,,,,,,,,"TRUE",,,"Mapping the Nutrient Status of Odisha’s Soils","Dixit","S","","","",,"","",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
