Other claims from this paper (12)
- Intervention effect Mixed salt irrigation at EC 3 depressed corn top yield by 17% relative to tap water.
- Intervention effect Mixed salt irrigation at EC 6 depressed corn top yield by 26% relative to tap water.
- Intervention effect MgSO4 water at EC 1 reduced corn tops by 19% more than mixed salts at equivalent salinity.
- Intervention effect MgSO4 water at EC 3 reduced corn tops by 38% more than mixed salts at equivalent salinity.
- Intervention effect MgSO4 water at EC 6 reduced corn tops by 59% more than mixed salts at equivalent salinity.
- Intervention effect Mg(HCO3)2 at EC 3 reduced corn top growth by 87% more than mixed salts.
- Intervention effect Mg(HCO3)2 depressed corn top growth more than twice as much as MgSO4.
- Observation Corn root growth depression was similar to top growth depression.
- Association Leaf Ca:Mg ratio was related to its ratio in soil solution.
- Intervention effect Leaf calcium and magnesium concentrations were nearly the same under Mg(HCO3)2 and MgSO4 at EC 1.
- Observation Leaf Mg:Ca ratio did not explain yield differences between magnesium salts.
- Mechanism The authors suggested nutrient imbalance and pH 9 could explain lower yields under Mg(HCO3)2.
