- Observation Corn showed tip burn as a boron toxicity symptom.
- Observation Beans and peas showed leaf mottling and necrosis.
- Observation Cucumbers showed leaf mottling and cupping.
- Association Fly ash raised hot-water soluble B proportional to rate and dependent on pH.
- Observation At media pH 6, 30% of total B was hot-water soluble.
- Intervention effect 33% fly ash compost significantly reduced bean biomass by 45%.
- Intervention effect 33% fly ash compost significantly reduced cucumber biomass by 55%.
- Intervention effect Fly ash compost increased bean tissue B about sixfold.
- Intervention effect Fly ash compost increased cucumber tissue B about fourfold.
- Association All tested crops had depressed economic yields when compost HWS-B exceeded 5 ppm.
- Recommendation Authors recommend managing compost factors and accounting for pH and cultivar preferences.
