Conteúdo: 	Detrimental factors acting on survival and competition of Bradyrhizobium japonicum strains can remarkably reduce nitrogen fixation and grain yield of soybeans. Biotic factors such as genetic compatibility among soybean cultivars and B. japonicum strains and competitiveness for nodule sites against the established population greatly affect the symbiosis. Among abiotic factors, associative soil acidity and stress conditions of moisture and temperature are major constraints on B. japonicum survival as well as on nodule formation and functioning. The use by inoculant manufactures of strains tolerant to shuch conditions minght be and important way to overcome the major problems which are being faced. Results covering these topics are discussed in this paper.
