Biostimulants are innovative agricultural products designed to enhance plant growth, health, and productivity by stimulating natural processes. Unlike traditional fertilizers, which provide nutrients, biostimulants work by improving the efficiency of the plant’s metabolic processes and increasing stress tolerance. They are derived from a variety of natural sources, including plant extracts, seaweed, beneficial bacteria, fungi, amino acids, and humic substances. These compounds enhance nutrient uptake, improve soil health, and boost plant resilience to environmental stressors such as drought, salinity, and extreme temperatures. Biostimulants can be applied to seeds, soil, or directly onto plants, making them versatile tools for promoting sustainable agriculture. By enhancing the plant’s own mechanisms for growth and defense, biostimulants contribute to healthier plants, higher yields, and better quality crops, while also supporting environmental sustainability.
