Study on Soil Acidification

Soil acidification could cause Indian soils to lose 3.3 billion tonnes of essential carbon, as revealed by a recent study.

Key highlights of the study:

• Globally, soils contain more than three times the carbon found in vegetation and twice that in the atmosphere.
• By 2100, changes in global warming and soil pH could reduce SIC by 1.35 to 5.83 gigatonnes under various warming scenarios.
• India and China are likely to experience the most significant SIC losses, primarily due to vast SIC reserves and widespread soil acidification from nitrogen additions.
• Annually, 1.13 billion tonnes of inorganic carbon are transferred from soils to inland waters, highlighting a significant cycle of carbon among land, atmosphere, freshwater, and oceans.
• The study underscores the importance of SIC in maintaining soil health, supporting ecosystem services, and aiding in climate change mitigation, recommending its consideration in carbon storage enhancement strategies.
