USO DE BIOESTIMULANTES À BASE DE AMINOÁCIDOS NA AGRICULTURA

Abstract

Biostimulants are substances used in agriculture to improve plant growth and productivity, acting in several ways, such as regulating plant metabolism, hormonal balance and increasing resistance to biotic and abiotic stresses. They can be composed of a variety of ingredients, including mineral salts, algae extracts, amino acids and microorganisms. These substances are applied in low doses and through different methods, such as seed treatments and foliar sprays, and are effective in stimulating the absorption of water and nutrients, controlling water stress and increasing resistance to pests and diseases. Amino acids, important components of biostimulants, play essential roles in plant metabolism, influencing the synthesis of proteins, plant hormones and the response to stress.In adverse situations, such as lack of water or pathogen attack, the application of amino acids can help plants fight free radicals and improve their ability to protect themselves against cellular damage. Furthermore, they also participate in the complexation of essential nutrients, such as zinc, iron and copper, optimizing the availability of these minerals for plants. Research indicates that the use of biostimulants, especially amino acids, can promote the development of more robust roots, improve seed germination and increase plant vigor, resulting in greater productivity. The strategic application of amino acids, taking into account the specific needs of each crop and environmental conditions, is essential to optimize their effects. However, despite the positive results observed in several studies, there is still controversy about the extent of the benefits of these products, and more studies are needed to fully understand their mechanisms of action and improve their applications in agriculture.
