Differential Tolerance of Soybean Varieties to an Acid Soil High in Exchangeable Aluminum¹

Soybean varieties, representing 10 maturity groups (from North to South), differed significantly in their tolerance to acid Bladen soil (pH 4.4) which contains a high level of KCl-extractable Al. Previous evidence that Al toxicity is the primary growth-limiting factor in this soil, and the observation that varietal differences were minimized or eliminated by liming the soil to pH 5.5, led to the conclusion that certain varieties differ in their tolerance to Al. Leaf chlorosis and petiole collapse, observed at low lime levels near the end of one experiment, were tentatively attributed to Al-induced Ca deficiency and not to a simple Ca deficiency in the acid soil.

Results of these studies suggest the possibility of breeding soybean varieties with greater tolerance to Al and, therefore, greater abilities to exploit acid, Al-toxic subsoils for both water and nutrients.
