Other claims from this paper (5)
- Intervention effect Managed Ultisol subsoils had greater effective CEC and base saturation than non-managed subsoils.
- Intervention effect KCl-exchangeable Al in managed subsoils was 23% lower at the 15-year location than in non-managed subsoils.
- Intervention effect KCl-exchangeable Al in managed subsoils was 65 and 100% lower at the two other locations than in non-managed subsoils.
- Intervention effect Sorghum growth was almost totally inhibited on non-managed subsoils amended with optimum nutrients when lime was absent.
- Intervention effect Long-term management improved Ultisol subsoils for sorghum root growth and development.
