Definition and Classification of Biostimulants

Biostimulants are natural products that, although they are not fertilizers or pesticides, have the ability to improve nutrient use efficiency, tolerance to abiotic stress, and crop quality. They are classified into several categories, including seaweed extracts, amino acids, beneficial microorganisms, and organic compounds such as humic and fulvic acids. Each of these biostimulants acts through different biochemical mechanisms, such as the activation of metabolic pathways in plants that increase nutrient absorption and improve disease resistance.

Types of Biostimulants and Their Applications

Biostimulants can be divided into several categories, each with specific applications in organic agriculture:

• Seaweed Extracts: These products, such as Ascophyllum nodosum, are rich in phytohormones that stimulate growth. They are commonly used in vegetable and fruit crops to improve root formation and resistance to water stress.
• Amino Acids: They act as precursors in the synthesis of proteins and bioactive compounds. They are applied in high nutritional demand crops such as tomatoes and peppers, increasing fruit quality and disease resistance.
• Beneficial Microorganisms: This includes bacteria and fungi that improve soil health and nutrient absorption. For example, the use of mycorrhizae in corn crops has shown a 40% increase in phosphorus absorption efficiency.
• Humic and Fulvic Acids: These organic compounds improve soil structure and water retention, being especially useful in sandy soils. Their application has been shown to increase production in cereal crops by 15%.

Mechanisms of Action of Biostimulants

The mechanisms of action of biostimulants are diverse and complex. For example, seaweed extracts, which contain phytochemicals such as auxins and cytokinins, promote cell growth and root formation. Studies have shown that the application of seaweed extracts can increase root production by 30%, improving water and nutrient absorption under stress conditions. On the other hand, amino acids can act as precursors of secondary metabolites that increase plant resistance to pathogens.

Interaction between Biostimulants and Abiotic Stress

Biostimulants are particularly effective in mitigating abiotic stress, which includes factors such as drought, salinity, and extreme temperatures. The application of biostimulants can activate defense mechanisms in plants, increasing the production of antioxidant compounds. For example, a study in wheat crops showed that the application of seaweed extracts during drought conditions increased proline concentration by 50%, helping plants tolerate water stress.

Price and Efficiency Comparison

It is important not only to consider the cost of biostimulants but also their effectiveness. For example, although beneficial bacteria may have a higher cost in Germany, their ability to improve soil microbiota and, therefore, nutrient availability can result in a 20% increase in crop production compared to the use of conventional fertilizers. This can justify the additional cost, especially in high-value crops.

Cost-Benefit of Biostimulants

A cost-benefit analysis is essential for farmers when considering the implementation of biostimulants. In a study conducted in vegetable greenhouses in the Netherlands, it was observed that the investment in biostimulants was recovered within six months through increased production and improved quality of the final product. Additionally, the reduction in the use of chemical inputs contributed to a decrease in operating costs.
