Última Interactions between magnesium, calcium, and aluminum on soybean root elongation Rev. Bras. Ciênc. Solo Silva,Ivo Ribeiro da; Ferrufino,Armando; Sanzonowicz,Cláudio; Smyth,Thomas Jot; Israel,Daniel W.; Carter Júnior,Thomas E.. Alleviation of Al rhizotoxicity by Ca and Mg can differ among species and genotypes. Root elongation of soybean [Glycine max (L.) Merr.] line N93-S-179 and cvs. Young and Ransom exposed to varying concentrations of Al, Ca and Mg were compared in two experiments using a vertically split root system. Roots extending from a surface compartment with limed soil grew for 12 days into a subsurface compartment with nutrient solution treatments maintained at pH 4.6 with either 0 or 15 µmol L-1 Al. Calcium and Mg concentrations in treatments ranging from 0 to 20 mmol L-1. Although an adequate supply of Mg was provided in the surface soil compartment for soybean top growth, an inclusion of Mg was necessary in the subsurface solutions to promote root elongation in...
