520	3		_aSoil degradation is a global environmental problem that puts at risk food security. Improving soil health is, therefore, a major challenge for sustainable agriculture. Biostimulants are products consisting of microorganisms or substances that stimulate plant metabolism, enhance crop performance, and increase plant resistance to biotic and abiotic stresses. A viable approach to reducing chemical inputs is using biostimulants to ensure improved production yield and quality. Humic substances, seaweed extracts, hydrolysed proteins and amino acids, plant extracts, inorganic compounds, beneficial microorganisms, chitosan and other biopolymers are the major categories of biostimulants discussed in this review. Through various mechanisms, such as nutrient absorption enhancement, root growth stimulation, antioxidant activity, and soil structure improvement, these biostimulants have an impact on the interface between soils and plants. Apart from soil degradation, soil and water pollution due to high concentrations of potentially toxic elements (PTEs)is also an important issue. Phytoremediation has the potential to be an effective and environmentally friendly approach for soil remediation and regeneration. Biostimulants have shown encouraging results in the field of phytoremediation by increasing plant biomass, enhancing metal accumulation in plant tissues, as well as improving the overall efficacy of removing PTEs from contaminated soils. The specific mechanisms through which biostimulants contribute to phytoremediation include metal complexion, stabilization and transport to non-vital plant compartments. However, those agro-environmental beneficial effects of biostimulants on degraded soils have not been thoroughly reviewed to date. Therefore, the aim of this review was to present a comprehensive study concerning the use of biostimulants and their interaction in the soil-plant interface under different conditions. This review presents the state of the art about the agricultural and environmental applications of biostimulants to soils as a sustainable agronomic tool to improve soil health and ameliorate PTE contaminated soils.
