The study looked at how adding lime to acidic soil in Ethiopia affects different forms of phosphorus and soil properties. They used different rates of lime and found that higher lime rates increased soil pH, reduced acidity, and increased available phosphorus. The results showed that adding lime improved the release of certain phosphorus forms while decreasing others. However, even with the highest lime rate, the amount of soluble phosphorus in the soil was still too low for plant needs. The study suggests that additional phosphorus may be needed to meet plant requirements.
