- Intervention effect Adding more boron increased alfalfa yields.
- Intervention effect Adding more boron increased alfalfa boron contents.
- Intervention effect Adding more boron increased toxicity symptoms in corn.
- Intervention effect Soil pH above 6 prevented boron toxicity in corn.
- Observation With standard phosphorus, corn grew best at soil pH 5 to 5.7.
- Observation With standard phosphorus, alfalfa grew best at soil pH 5 to 5.7.
- Observation At pH above 6, phosphorus deficiency retarded crop growth.
- Intervention effect At pH above 6, high phosphorus nearly doubled corn dry-weight yield.
- Observation Liming-induced phosphorus deficiency decreased with time.
- Mechanism Parallel boron and phosphorus behavior supports a common pH-dependent soil binding mechanism.
