Biostimuloivat

Biostimuloivat refers to substances or microorganisms that, when applied to plants, seeds, or the rhizosphere, stimulate natural processes to enhance nutrient uptake, nutrient efficiency, tolerance to abiotic stress, and crop quality. These products are not fertilizers or pesticides, although they can be used in conjunction with them. The mode of action for biostimulants varies widely and depends on the specific type of biostimulant.

Common categories of biostimulants include humic and fulvic acids, seaweed extracts, protein hydrolysates and other amino acids, beneficial microorganisms (such as bacteria and fungi), and silicon. Humic substances can improve soil structure and nutrient availability. Seaweed extracts contain a range of plant growth regulators, minerals, and other beneficial compounds. Protein hydrolysates provide readily available amino acids that plants can use for protein synthesis and stress response. Beneficial microbes can enhance nutrient solubilization, improve root development, or induce plant resistance to pathogens. Silicon can strengthen plant cell walls, improving resistance to lodging and certain diseases.

The primary goal of using biostimulants is to improve plant health, vigor, and resilience, ultimately leading to increased yield and quality. Their application can be particularly beneficial under suboptimal growing conditions, such as drought, salinity, or nutrient deficiency. Research and development in the field of biostimulants are ongoing, with a focus on understanding their complex mechanisms of action and optimizing their formulation and application for various crops and environments. Regulatory frameworks for biostimulants are evolving globally to ensure product efficacy and safety.
