An association between the tolerance to the Al toxicity and the P absorption capacity of plants was described by Foy & Brown (Soil Sci. Soc. Am. Proc. 28: 27, 1964). The source of N, on the other hand, affects both the Al toxicity (Cunha Filho, XIII Reun. Bras. Milho e Sorgo, p. 113, 1980) and the P absorption (Miller, Plant Root and Its Environment, p. 646, 1974).
