Microbial (e.g. arbuscular mycorrhizal fungi, nitrogen-fixing bacteria) and non-microbial (e.g. algae extracts, protein hydrolysates and humic substances) biostimulants are reconized as usefull tools for increasing crop yield and product quality, nutrient use efficiency and crop resistance to abiotic stress. Biostimulant use in agriculture follows an increasing trend worldwide. Biostimulants are therefore increasingly considered by farmers as technical means to enhance crop productivity by reducing the negative impact of adverse pedo-climatic conditions on crops. Biostimulants are also considered useful for a sustainable intensification of crop production, reducing the impact of some cultural practices on the environment, preserving natural resources and increasing ecosystem services.
