Introduction

In the competitive world of agriculture, profitability is one of the main concerns for producers. Biostimulants have established themselves as an effective tool for improving crop profitability in Europe, offering sustainable solutions that optimize production and the quality of harvests. In this article, we will explore how biostimulants can transform your agricultural approach and contribute to a more sustainable future.

What are biostimulants?

Biostimulants are natural products that, when applied to plants, stimulate physiological processes that enhance growth and crop yield. These can include plant extracts, microorganisms, and bioactive compounds that promote soil health and plant nutrition. Their use has increased due to the growing demand for more sustainable and environmentally friendly agricultural practices.

Types of biostimulants

There are several types of biostimulants, including:

• Microorganism-based biostimulants: These products use beneficial microorganisms that improve soil health and nutrient absorption. For example, certain mycorrhizal fungi have been shown to increase the root absorption surface area, which can enhance phosphorus assimilation by 50% in crops like corn.
• Seaweed extracts: Known for their ability to stimulate growth and stress resistance. Research has indicated that seaweed extracts can increase the activity of antioxidant enzymes in plants, allowing them to better tolerate drought and salinity conditions.
• Amino acids: Compounds that provide essential nutrients and improve crop quality. A recent study showed that the application of specific amino acids in tomatoes increased vitamin C content by 15%, thus enhancing their nutritional and commercial value.

Plant-derived biostimulants

Plant-derived biostimulants are another important group that includes extracts from plants such as nettle, comfrey, and ginseng. These extracts contain phytohormones, such as auxins and gibberellins, which regulate plant growth and development. For example, the application of nettle extract has been shown to increase disease resistance in tomato crops, reducing pest incidence by 30%.

Agricultural waste-derived biostimulants

The use of agricultural waste as raw material for the production of biostimulants is a growing trend. These biostimulants are obtained from by-products of the agri-food industry and can contribute to the circular economy. For example, the use of compost from fruit and vegetable waste has been shown to increase microbial activity in the soil, improving nutrient availability and fostering a more balanced ecosystem.

Benefits of biostimulants

The application of biostimulants offers a number of significant benefits for crops:

1. Improved nutritional efficiency

Biostimulants help plants absorb nutrients more efficiently, leading to more effective use of fertilizers and reduced dependence on chemical products. This not only reduces costs but also minimizes environmental impact. According to a report from the FAO, nutrient use efficiency is key to agricultural sustainability. For example, it has been reported that the application of biostimulants can increase nitrogen use efficiency by 30%, meaning farmers can achieve higher yields with fewer inputs. Additionally, biostimulants can enhance the mobilization of micronutrients, facilitating their absorption in situations where their availability is limited.

2. Increased stress resistance

Biostimulants can increase plants’ tolerance to adverse conditions, such as droughts or saline soils. This is especially relevant in regions of Europe where climatic conditions are changing and farmers face new challenges. A study conducted in Spain demonstrated that the use of a seaweed extract-based biostimulant increased the survival of pepper seedlings under drought conditions by 40% compared to a control group. Furthermore, it has been observed that biostimulants can improve the activity of heat shock proteins, which play a crucial role in plants’ response to thermal stress. In an experiment in Italy, it was found that tomato plants treated with a biostimulant showed a 25% increase in the activity of these proteins, allowing them to better survive extreme temperatures.

3. Improved quality of harvests

Products treated with biostimulants often show improvements in quality parameters, such as flavor, color, and shelf life. This translates into higher market value and better consumer satisfaction. For example, in strawberry crops, it was observed that fruits treated with biostimulants had 20% more sugar content, improving their palatability and attracting more consumers. Additionally, biostimulants can increase the content of bioactive compounds, such as antioxidants and vitamins, enhancing the nutritional value of crops. A study in broccoli crops revealed that the application of biostimulants increased glucosinolate content, beneficial compounds for health, by 30%.

4. Stimulation of root growth

Biostimulants also promote the development of the root system, allowing plants to access more nutrients and water. A study conducted in corn crops showed that the application of a microorganism-based biostimulant increased root length by 25%, resulting in better crop yield under water stress conditions. This effect is due to the production of growth hormones by microorganisms, which stimulate the formation of new roots. In another study, it was demonstrated that the use of amino acid-based biostimulants promoted more aggressive root development in sunflower crops, increasing the plants’ ability to explore the soil and absorb water.

How to apply biostimulants

The correct application of biostimulants is crucial to maximize their benefits. Some tips include:

1. Know the right timing

The application of biostimulants should be done at key moments in the crop cycle, such as at planting or during critical growth phases. This ensures that plants can make the most of the benefits. For example, applying an amino acid-based biostimulant during the flowering phase can increase fruit production in vegetable crops by up to 25%. Additionally, it is important to consider climatic conditions and the health status of the plants to determine the optimal time for application. In a trial with cucumber crops, it was observed that early application of a microorganism-based biostimulant resulted in a significant increase in flowering and fruit set.

2. Choose the right type of biostimulant

It is essential to select the appropriate biostimulant according to the specific needs of each crop and soil conditions. In Europe, regulations are being developed to ensure the quality and effectiveness of these products. The right choice may depend on factors such as soil type, climate, and present pests. For example, a biostimulant that has shown good results in clay soils may not be as effective in sandy soils. Additionally, combining different types of biostimulants can result in synergies that further enhance the desired effects. In a greenhouse study, it was found that the combination of a seaweed-based biostimulant with a microorganism-based one resulted in a 35% increase in tomato production compared to the use of individual products.

3. Monitor and analyze

Evaluating crop performance and soil health after the application of biostimulants is key to adjusting strategies and continuously improving results. This can include soil analysis, yield measurements, and quality assessments of harvested products. Implementing a monitoring system allows farmers to identify which practices are most effective and make real-time adjustments, thus optimizing long-term profitability. For example, the use of satellite imaging technology can help assess crop health and the effectiveness of applied biostimulants. A farmer in Portugal used drones equipped with sensors to map variability in crop growth and adjust the application of biostimulants accordingly, achieving a 20% improvement in overall yield.

Case studies and practical examples
