Antagonism of magnesium and aluminium in bean and wheat
1989
Kiss, S.A. (Borsod Chemical Works, Kazincbarcika (Hungary))
Al has a toxic effect primarily on the roots of plants, which become deformed and show a coralloid growth habit, and it reduces the ability of roots to take up nutrients in general, and Mg in particular which thereby lessens the yield. The increasing Mg content of the nutrient solution gradually hinders the Al uptake and thus decreases the toxicity. According to the author's investigations, Al and Mg are mutual antagonists. Tolerance requires the ratio of Mg:Al to be above 2 in the nutrient solution. The toxicity of Al is species and variety dependent, as demonstrated on bean and wheat plants. Al also damages Rhizobium, whereas Mg increases the tolerance in this case too.
