Soil Acidity as a Constraint: Soil Acidity is a long-standing constraint being faced by agricultural productivity in the context of the province of Odisha, located in the country of India. Recent estimates have found more than half of the agricultural lands in the province to be soil acidic in nature due to high rainfall, intense weathering, as well as continuous leaching of base cations (Government of Odisha, 2025). Soil Acidity can be defined as soils marked by aluminum toxicity, toxicities of metals such as manganese, phosphorus fixation, as well as low microbial populations (Sharma & Gupta, 2006). The present study compiles existing scientific research work on soil Acidity affecting agricultural lands within the province of Odisha.
