Biostimulants are products that stimulate plant nutrition processes. Their ability to improve the soil quality and increase nutrient use efficiency is considered an element of sustainable agriculture. They help plants to use nutrients efficiently, to be more tolerant of drought, extreme temperatures, salinity, and other abiotic stresses. Plant Biostimulants are often derived from natural sources, and they positively impact roots, stems, leaves, flowers, and fruits. They support the root growth, protect plants from photosynthetic activity during stress, and even improve water use capability
