- Intervention effect Lime reduced soil pH.
- Intervention effect Lime reduced exchangeable soil aluminium.
- Intervention effect Lime increased soil available phosphorus.
- Intervention effect Lime at 2 tons ha −1 maintained soil pH ≥ 5.5 for 2 years.
- Intervention effect Lime at 4 tons ha −1 maintained soil pH ≥ 5.5 for 3 years.
- Intervention effect Lime at 6 tons ha −1 maintained soil pH ≥ 5.5 for 4 years.
- Intervention effect The recommended 26 kg P ha −1 rate was inadequate to raise available phosphorus to the critical level.
- Recommendation Reapplication of 52 kg P ha −1 after every cropping season was deemed necessary to maintain critical soil phosphorus.
- Recommendation Reapplication after two cropping seasons was deemed necessary for the combined phosphorus and lime treatment.
- Intervention effect Four tons of lime increased four-year mean grain yield by 0.34 tons ha −1.
- Intervention effect Six tons of lime increased four-year mean grain yield by 0.50 tons ha −1.
- Intervention effect Phosphorus fertilizer at 26 kg P increased four-year mean grain yield by 0.58 tons ha −1.
- Intervention effect Phosphorus fertilizer at 52 kg P ha −1 increased four-year mean grain yield by 1.17 tons ha −1.
- Association Agronomic phosphorus use efficiency increased with lime rate.
- Association Phosphorus fertilizer recovery efficiency increased with lime rate.
- Association Agronomic phosphorus use efficiency decreased with phosphorus fertilizer rate.
- Association Phosphorus fertilizer recovery efficiency decreased with phosphorus fertilizer rate.
- Recommendation Combined lime and phosphorus fertilizer applications were recommended to enhance maize production on acid soils.
