Introduction

Biostimulants have become an essential tool for European farmers looking to improve their harvest. These natural products, based on plant extracts and microorganisms, optimize the nutritional efficiency of crops, increasing their resistance to environmental stress factors and improving the quality of production. In this article, we will explore how biostimulants can revolutionize agriculture in Europe and how they can be implemented in your daily farming practices.

What are Biostimulants?

Biostimulants are substances or microorganisms that, when applied to plants or soil, promote natural processes that enhance growth and quality of crops. These products not only increase nutrient availability but also help plants cope with adverse conditions such as droughts or diseases. They differ from traditional fertilizers, as their function is to promote plant health rather than simply provide nutrients. According to the FAO, the use of biostimulants is on the rise due to their contribution to sustainable agriculture.

Types of Biostimulants

• Plant extracts: derived from plants that contain bioactive compounds. These extracts may include amino acids, humic and fulvic acids, which improve nutrient availability in the soil and stimulate root growth.
• Microorganisms: bacteria and fungi that enhance soil and plant health. For example, the application of Mycorrhizae can increase phosphorus absorption by up to 80%, which is crucial for root development and flowering.
• Bioactive compounds: substances that stimulate plant growth. These compounds may include plant hormones such as auxins and gibberellins, which regulate growth and development processes in plants.

Algal-Based Biostimulants

Algal-based biostimulants are particularly effective due to their richness in phytohormones, polysaccharides, and micronutrients. Studies have shown that the application of seaweed extracts can increase biomass production in rice crops by 20%, thanks to their ability to enhance photosynthetic activity and overall plant health. Additionally, these biostimulants can help regulate plant metabolism during stress periods, such as droughts or high temperatures, by increasing the accumulation of osmoprotective compounds.

Biochemical Mechanisms of Biostimulants

Biostimulants act at the biochemical level by influencing various metabolic pathways. For example, the amino acids present in plant extracts can activate protein synthesis, which not only promotes growth but also increases resistance to diseases. A study published in the Journal of Agricultural and Food Chemistry demonstrated that the application of specific amino acids can induce the production of phytoalexins, compounds that plants use to defend themselves against pathogens.

Studies on Mechanisms of Action

Recent research has delved into understanding how biostimulants affect plant physiology. For instance, a study on corn crops found that the application of an amino acid-based biostimulant not only increased biomass production by 30% but also improved the activity of the enzyme rubisco, key for photosynthesis. This suggests that biostimulants can have a direct impact on photosynthetic efficiency, translating into higher crop yields.

Benefits of Biostimulants in Crops

The implementation of biostimulants in European crops provides multiple benefits:

• Increased nutritional efficiency: they help plants absorb nutrients more effectively. A study conducted by Wageningen University showed that the use of biostimulants can increase nitrogen absorption by 40% in corn crops.
• Improved stress tolerance: they strengthen plants’ resistance to droughts, frosts, or diseases. For example, the application of Trichoderma, a beneficial fungus, has proven effective in reducing water stress in tomato plants, increasing their yield by 25% under drought conditions.
• Increased quality of the harvest: the products obtained are more nutritious and have better flavor. An analysis of grapes treated with biostimulants showed a 15% increase in sugar content, resulting in higher quality wines.
• Contribution to sustainability: they reduce the need for chemical inputs, favoring sustainable agricultural practices. This is especially relevant in Europe, where agricultural policies aim to reduce the use of pesticides and synthetic fertilizers.

Mechanisms of Action of Biostimulants

Biostimulants act through various mechanisms that can be classified into three main categories:

• Growth stimulation: They increase the activity of enzymes involved in photosynthesis and respiration, resulting in faster and more vigorous growth. For example, the amino acids present in plant extracts can promote protein synthesis and improve chlorophyll formation.
• Improvement of soil health: Beneficial microorganisms enhance soil structure and promote biological activity, increasing nutrient availability. The addition of Azospirillum, for example, can increase the population of beneficial bacteria in the soil, improving nutrient mineralization.
• Regulation of plant physiology: Biostimulants can influence the genetic expression of plants, regulating processes such as disease resistance and tolerance to adverse conditions. A study in onion crops showed that the use of a biostimulant based on algal extracts increased the expression of defense-related genes, improving resistance to pathogens.

Interaction with the Soil Microbiome

A crucial aspect of biostimulants is their ability to interact with the soil microbiome. These products can promote the growth of beneficial microorganisms that, in turn, help plants access nutrients more efficiently. For example, the application of microorganism-based biostimulants can increase microbial diversity in the soil, which is correlated with greater stability and health of the soil ecosystem. A study showed that soils treated with biostimulants exhibited a 50% increase in microbial species diversity, leading to better nutrient availability for plants.

Application of Biostimulants

The efficient use of biostimulants requires a clear understanding of their characteristics and the needs of the crops. It is important to follow the manufacturer’s recommendations to achieve effective application. Some application methods include:

• Foliar application: spraying directly onto the leaves for rapid absorption. This method is particularly effective in horticultural crops, where visible results can be obtained in a short period. A study in lettuce crops demonstrated that foliar application of biostimulants increased harvest weight by 20% compared to the untreated control.
• Incorporation into the soil: mixing into the substrate before planting. This method is ideal for cereal crops, where biostimulants can improve soil health and nutrient availability from the start. A trial conducted in wheat fields showed that the incorporation of biostimulants can increase yield by 15% due to improved nutrient absorption.
• Drip irrigation: integrating into the irrigation system for uniform distribution. This technique is especially useful in water-scarce regions, where biostimulants can be applied efficiently. In tomato crops, drip irrigation with biostimulants resulted in a 30% increase in production compared to conventional irrigation.

When applying biostimulants, it is essential to conduct a soil and plant analysis to determine specific needs and maximize results. This ensures that the application is efficient and that the expected benefits are obtained.

Considerations for Application

It is essential to consider certain factors when applying biostimulants:

• Timing of application: Timing is key. Applying biostimulants at critical moments in the plant’s growth cycle, such as during the flowering phase or during stress periods, can maximize their effectiveness.
• Environmental conditions: Weather conditions, such as temperature and humidity, can affect the efficacy of biostimulants. For example, it is recommended to avoid foliar applications during the hottest hours of the day to prevent rapid evaporation.
• Compatibility with other inputs: It is important to check the compatibility of biostimulants with other fertilizers or pesticides being used. Some biostimulants can enhance the effectiveness of other inputs, while others may interfere with their action.

Application Practices in Various Crops

The application of biostimulants should be adapted to the specific characteristics of each crop. For example:

• Fruit trees: In apple crops, the application of amino acid-based biostimulants during the fruit growth phase has been shown to increase the size and quality of the fruit by 25%.
• Vegetables: In pepper crops, the use of algal-based biostimulants has shown to increase disease resistance and improve fruit quality, resulting in a 30% increase in market value.
• Cereals: In the case of wheat, the application of a biostimulant containing beneficial microorganisms has resulted in a 15% increase in yield per hectare by improving nitrogen and phosphorus absorption.

Practical Examples of Field Application

The implementation of biostimulants in the field has proven effective in various situations. In a barley crop in Germany, farmers applied a microorganism-based biostimulant at the beginning of the growth cycle, resulting in an 18% increase in final yield. Soil analyses showed an improvement in soil structure and greater biological activity, contributing to the overall health of the crop.

Another example is observed in a greenhouse in Spain, where a seaweed-based biostimulant was used in strawberry crops. The results showed a 25% increase in strawberry size and better disease resistance, allowing a 40% reduction in fungicide use during the season.
