Other claims from this paper (12)
- Association The greater salt tolerance of B. oleracea seemed to be related to maintained shoot K+ and restricted Na+ and Cl- in the hydroponic screening.
- Observation B. carinata showed maintained shoot K+ and restricted Na+ and Cl- at the lower salinity level in the hydroponic screening.
- Intervention effect The organic amendments increased the cation exchange capacity of the soil and the concentrations of exchangeable K+ and Mg2+.
- Observation The equilibrium between soluble and exchangeable K+ tended toward the exchangeable forms in the amended soil.
- Observation Na+ remained mainly in the soil solution in the amended soil.
- Intervention effect Addition of manure significantly increased shoot growth of B. carinata.
- Intervention effect Addition of manure significantly increased shoot growth of B. oleracea.
- Intervention effect Compost markedly improved shoot growth of B. oleracea.
- Mechanism The manure and compost effects on shoot growth may be related to increased shoot tissue K+:Na+ ratios and total phosphorus concentrations.
- Intervention effect When tomato was grown in the amended soils used for B. oleracea, its growth was not significantly greater than in the control.
- Intervention effect The organic amendments raised the water-extractable boron concentration of the soil.
- Intervention effect Plant tissue boron concentrations of Brassica were unaffected by the organic amendments.
