The introduction of various fertilizer rates led to a change in the amount of nutrients in the irrigated gray-brown soils of the Absheron Peninsula. The amount of nitrates and ammonia absorbed in soils under legumes increased with increasing fertilization rates. In the course of the experiment, the maximum amount of available phosphorus in the control compared with the soils under legumes was recorded at the early stages of their development. In connection with the formation of vegetative and generative organs of plants during the growing season, the use of mobile phosphorus from the soil by plants increased. The minimum amount of mobile phosphorus in the soil was observed when legumes were fully ripe. A similar process was observed in the content of exchangeable potassium in the soil.
