Nowadays, the agriculture’s target is the reach of an amount of crop production that can cover the need to feed growing
world population with the crucial challenge of respecting the environment. Several environmental constraints are limiting world
agricultural production, mainly the preponderance of calcareous soils suffering from ferric and phosphoric deficiencies. In
calcareous soils, legumes were considered as an alternative solution to retrieve a fertile soil without the abusive use of chemical
fertilizers. The ability to establish a symbiotic associations with nitrogen-fixing soil bacteria is the way used by legumes to restore
soil organic matter and to improve soil fertility. Legumes remain a source of healthy food while respecting the environment. This
mini review describes the importance of legumes for Fe and P deficient soils management through sustainable practices.
