Other claims from this paper (12)
- Intervention effect Lettuce growth was depressed by Fe deficiency in the alkaline sand.
- Intervention effect Soil-applied Fe compounds raised Fe concentrations in lettuce.
- Intervention effect The Fe chelates also increased lettuce yields.
- Intervention effect Soil-applied Fe compounds had no statistically significant effect on Fe concentrations in ryegrass.
- Intervention effect All soil-applied chelates equally decreased Mn concentrations in lettuce.
- Intervention effect In alkaline sand, soil application of Fe-EDDHA elevated Cu concentrations in lettuce.
- Intervention effect In alkaline sand, soil application of Fe-EDDHA depressed Zn concentrations in lettuce.
- Intervention effect The chelates increased Zn concentration in ryegrass.
- Intervention effect Foliar application of Fe-EDDS increased Fe concentrations in lettuce.
- Intervention effect Foliar application of Fe-EDDS increased Fe concentrations in ryegrass most of the compounds tested.
- Intervention effect Fe-EDDHA depressed Mn and Zn concentrations in lettuce more than other Fe compounds did.
- Mechanism The authors suggest another mechanism, in addition to Fe, transmits a signal from shoot to roots that affects micronutrient uptake in lettuce.
