Other claims from this paper (6)
- Intervention effect Aluminium reduced soybean root and shoot lengths and root dry weight.
- Intervention effect Organic anions alleviated aluminium phytotoxicity in soybean in the order oxalate, citrate/tartrate/malate, malonate, then lactate.
- Observation The organic anions differed in aluminium complexation effectiveness, with citrate highest and lactate lowest.
- Mechanism Organic anions provided benefits beyond simple complexation of phytotoxic aluminium.
- Intervention effect Citrate and oxalate needed a concentration at least equal to aluminium to significantly reduce phytotoxicity.
- Observation Twice as much oxalate as citrate was required for the same reduction in aluminium phytotoxicity.
