In a global economic system conditioned by limited resources and faced with increasing worldwide demand as well as increasing environmental degradation, the only viable option remains the resource-efficient, circular economy. Our planet has limited quantities of essential resources such as water and soil. This paper provides information on research carried out using steel slag as a soil amendment and its influence on agricultural crops. The use of steel slag on chromic luvisols from the didactic farm Moara Domneasca has been successfully used as an amendment to correct soil reaction as an alternative to the currently used acid soil correction materials (limestone and dolomite). On the other hand, since slag contains essential plant nutrients such as P, Mn, Fe, Ca, etc. in different concentrations, its application has positively influenced crops production. This use allows reducing the consumption of natural resources and provides a great agricultural, environmental and economic gain by minimizing the negative environmental effects of steel slag.
