- Intervention effect Humate incorporated to 10 cm depth increased root mass by 45% compared with the control in sand culture.
- Intervention effect Humate incorporated to 10 cm depth increased root mass by 38% in the lower layer compared with the control in sand culture.
- Intervention effect Granular humate increased maximum root length by 15% compared with non-treated turf in sand culture.
- Intervention effect No foliar-applied humic acid source consistently gave rooting superior to the control in sand or solution culture.
- Intervention effect Nitrogen, calcium and magnesium uptake were relatively unaffected by humic substance application.
- Intervention effect Iron uptake was relatively unaffected by humic substance application.
- Intervention effect Incorporated humate increased plant phosphorus concentration by 3 to 5% in sand culture.
- Intervention effect Foliar application of soil, peat or Leonardite-derived humic acid increased plant phosphorus concentration by 3 to 5% in sand culture.
- Mechanism Humic acids may have limited growth-promoting effects on creeping bentgrass plants adequately supplied with nutrients (hypothesis).
