The authors made a lanthanum chelate with amino acids from soybean protein hydrolysate and tested it on rice seedlings exposed to copper. At 20 mg/L the chelate outperformed inorganic lanthanum salts in promoting growth and reduced copper in rice tissues.
Key numbers
- Maximum chelation rate 94.95% (abstract).
- A 20 mg/L chelate treatment reduced copper in seedling tissues and outperformed inorganic lanthanum salts (abstract).
Methods (brief)
Chelate synthesis and characterization by UV-vis, FTIR and electron microscopy; hydroponic seedling tests with copper stress.
Evidence fitness
Shows that new lanthanum agrochemicals are being developed for crops. It reports no lanthanum residue data and does not support exposure statements.
Limitations
Seedling hydroponics; no lanthanum analysis of plant tissue reported in the abstract.
