Biostimulants are substances or microorganisms that are applied to plants or soil to enhance plant growth and development, improve nutrient uptake, and improve plant tolerance to environmental stress. Biostimulants are distinct from fertilizers in that they do not supply nutrients directly to the plant, but rather enhance the plant's ability to uptake nutrients and use them more efficiently. https://www.fortunebusinessinsights.com/industry-reports/biostimulants-market-100414
