Resumen:
Nitrogen is the nutrient that mostly determines the growth and performance of the cultivations in the soils of the Region Pampeana, followed in importance by phosphorus. An option for the use of fertilizers would be the utilization of plant growth promoting bacteria (PGPB). The action of the PGPB is manifested in different mechanisms such as; control of deleterious organisms; atmospheric nitrogen fixation; and mechanisms for moving and solubilising minerals like phosphorus and sulphur and arrange them for the plant growth. The action of the PGPB microorganisms is determined by biotic and abiotic factors, in this case it is important the salinity, sodicity, and flood conditions.
