I and GTP II, only 2.4% of the severe acid soil area (3.7 million hectares) have been treated with lime. With this trend, it may take over 200 years to fully treat the strong acidic soil of Ethiopia. Overall, efforts to treat soil acidity so far have lagged expectations and now require effective interventions.

The acidic soils in Ethiopia are most commonly found in highland areas, including parts of the Rift Valley, the central and northern highlands, and some regions in the southwest.

A pH of 7.0 is defined as neutral. Values below 7.0 are acidic, and values above 7.0 are basic or alkaline. Small changes in numbers indicate large changes in soil acidity. A soil with a pH of 5 is 10 times more acidic than a soil with a pH of 6 and 100 times more acidic than a soil with a pH of 7.

Acid soils are a major constraint to agricultural productivity in many parts of sub-Saharan Africa, including Ethiopia. Restoring soil pH to optimal ranges for agriculture can have a significant impact on yields, particularly for acid intolerant crops like wheat and barley. The application of agricultural lime is the standard corrective, although the large …
