Considering the fact that the world's population shows an upward trajectory from one year to another, the need to ensure security at the global level by supplementing the production of agricultural crops has become a primary objective. Thus, in order to ensure the intake of proteins necessary for human consumption but also to meet the needs of the large paint-producing industries as well as livestock farms, soybean culture represents the conventional option for this demand, which is why in recent years this plant has become one of the most cultivated worldwide, due to the multiple properties it possesses, such as: symbiotic fixation of atmospheric nitrogen, it is an oleaginous plant and the protein content of the seeds is very high. Therefore, due to the desire to achieve quantitatively higher yields, the amount of chemical fertilizers applied either on the soil or incorporated at the time of sowing has increased, this causes soil pollution over time, which is why the decision was made to carry out this retrospective study in order to highlight in what proportions the distribution of chemical fertilizers influences the symbiotic fixation of atmospheric nitrogen by means of nitrogen-fixing bacteria and how it is possible that by cultivating this plant we can provide the preceding crop with the necessary amount of Nitrogen without carry out an additional application of chemical fertilizers, thus ensuring a healthier and more profitable crop but also a less polluted soil.
