Biostimulants are natural substances or microorganisms that enhance plant growth and health. They work by improving nutrient uptake, increasing resistance to stress, and promoting overall plant vigor. Common types of biostimulants include humic acids, seaweed extracts, and beneficial bacteria. These products are used in agriculture and horticulture to boost crop yields and improve soil quality. Unlike fertilizers, which provide nutrients, biostimulants focus on enhancing the plant's natural processes. This can lead to healthier plants that are better equipped to withstand environmental challenges, such as drought or disease.
