Other claims from this paper (11)
- Intervention effect Biosolids organic carbon did not increase crop leaf tissue zinc concentration relative to soil without organic carbon.
- Intervention effect Flooding decreased leaf dry matter yield in all three crops, particularly in organic waste amended soil.
- Intervention effect Flooding decreased leaf tissue zinc concentrations in all three crops, particularly in organic waste amended soil.
- Observation Rice leaf zinc was higher than wheat and barley leaf zinc.
- Association Exchangeable soil zinc correlated positively with leaf zinc concentration across the three crops.
- Association Nonexchangeable soil zinc correlated negatively with leaf zinc across the three crops.
- Observation Reduced soil conditions depressed exchangeable zinc in ponded soil.
- Observation Reduced soil conditions enhanced nonexchangeable zinc in ponded soil.
- Observation Added organic carbon increased nonexchangeable zinc in flooded soil.
- Observation Added organic carbon did not affect nonexchangeable zinc in unflooded soil.
- Mechanism The authors interpret crop zinc availability as more dependent on flood induced pH changes than organic carbon addition.
