e0“Increasing soil pH also decreased the nickel (Ni) and zinc (Zn) concentrations in plants in the first year crop but the copper (Cu) concentration was not consistently affected by soil pH.”
t0“Wheat (Triticum aestivum), carrot (Daucus carota L.), and lettuce (Lactuca sativa) were grown as test crops.”

Other claims from this paper (10)
- Intervention effect Crop yields were not consistently affected by increasing soil pH.
- Intervention effect Plant cadmium concentration decreased with increasing soil pH in both soils across all three years.
- Intervention effect Soil pH produced significant cadmium concentration differences in wheat.
- Intervention effect Soil pH produced significant cadmium concentration differences in carrot.
- Intervention effect Increasing soil pH decreased plant zinc concentration in the first year.
- Intervention effect Plant copper concentration was not consistently affected by soil pH.
- Intervention effect The pH effect on metal concentrations was stronger in moraine than alum shale soil.
- Intervention effect Increasing soil pH decreased DTPA-extractable soil cadmium.
- Intervention effect Increasing soil pH decreased NH4NO3-extractable soil cadmium, with the stronger pH response of the two extractants.
- Method / resource DTPA and NH4NO3 extractants related equally well to plant cadmium concentration.
