Introduction Some comments about a better use of biological nitrogen fixation in rice cultivationtilization inevitably increased yields: it was the beginning of the triumphal era of fertilizers. In the thirties began the era of legume inoculation: and this again was due to a very simplistic situation in Western countries: the absence of bacterial symbionts adapted to crops such as soybeans.
