Biostimulants to Improve the Quality of European Crops

Introduction

Biostimulants are products increasingly used in European agriculture to improve crop quality. These compounds, made from natural extracts and beneficial microorganisms, have a positive impact on plant productivity and health. In this article, we will explore how biostimulants can transform your crops and maximize their quality, strengthening the link between sustainability and profitability.

What are biostimulants?

Biostimulants are substances that, when applied to plants or soil, improve nutrient availability and promote plant growth. Through biological processes, these products help plants overcome adverse conditions, such as droughts or nutrient-poor soils. In Europe, biostimulants are a key component of sustainable agriculture, aligning with environmental regulations and seeking more efficient production.

Classification of biostimulants

There are different types of biostimulants, which can be classified into:

• Plant extracts: derived from plants that stimulate growth and stress resistance.
• Microorganisms: bacteria and fungi that improve soil health and nutrient absorption.
• Bioactive compounds: substances that influence plant physiological processes.

Plant extracts

Plant extracts are products obtained from plants that contain phytohormones, amino acids, polysaccharides, and other bioactive compounds that promote plant growth and development. For example, seaweed extract is rich in auxins and cytokinins, which can increase germination rates and improve resistance to water stress. Studies have shown that applying seaweed extracts can increase the yield of crops such as corn and rice by 10-20% under stress conditions.

Mechanisms of action of plant extracts

Plant extracts act through various mechanisms. The phytohormones present, such as auxins and gibberellins, regulate cell growth and root elongation, optimizing water and nutrient absorption. Additionally, these extracts can induce the synthesis of proteins involved in stress response, improving plant tolerance. A study conducted on onion crops showed that the use of plant extracts increased the activity of antioxidant enzymes, contributing to better adaptation to abiotic stress conditions.

Microorganisms

Microorganism-based biostimulants include bacteria and fungi that establish symbiosis with plant roots, improving nutrient and water absorption. One example is the application of mycorrhizae, which can increase phosphorus absorption by up to 50% and improve the overall health of the root system. This is particularly beneficial in soils with low nutrient availability, where mycorrhizae can help plants access resources that would otherwise be out of reach.

Beneficial interactions of microorganisms

Microorganisms can also stimulate the production of root exudates, which attract other beneficial microorganisms and promote the formation of soil aggregates, improving soil structure. The application of Azospirillum, for example, has been shown to increase nitrogen fixation in maize crops, resulting in a reduced need for nitrogen fertilizers. In one study, maize crops treated with Azospirillum showed a 15% increase in yield compared to controls.

Bioactive compounds

Bioactive compounds such as amino acids, humic and fulvic acids, and other secondary metabolites play a crucial role in regulating physiological processes in plants. For example, the application of amino acids can stimulate protein synthesis and improve resistance to abiotic stress, resulting in more vigorous growth and higher crop quality. Research has shown that the application of amino acids can increase protein content in wheat and barley crops by 15-25%.

Function of humic and fulvic acids

Humic and fulvic acids are organic compounds that improve soil structure, increase cation exchange capacity, and facilitate nutrient availability. Their application has been shown to increase soil moisture retention, which is especially beneficial in drought-prone regions. A study on onion crops showed that the application of humic acids increased production by 20%, by improving water and nutrient use efficiency.

Benefits of biostimulants

The use of biostimulants brings multiple benefits that directly impact crop quality:

Improved soil quality

Biostimulants promote microbial activity in the soil, leading to greater fertility and a better nutrient balance. This translates into healthier and more productive crops. For example, applying microorganism-based biostimulants can increase soil microbial biomass by 30-50%, improving organic matter decomposition and nutrient availability for plants.

Increased soil biodiversity

The use of biostimulants also contributes to increasing soil biodiversity, which is essential for maintaining a healthy agricultural ecosystem. Soil with greater microbial diversity is more resilient to pests and diseases, which can reduce the need for pesticides. Studies have shown that biostimulants can increase the diversity of microbial species in the soil by 40%, resulting in a more balanced and productive system.

Enhanced stress resistance

Plants treated with biostimulants show greater tolerance to adverse conditions, such as droughts or high salinity, allowing for more robust growth even in difficult situations. Research has shown that crops treated with biostimulants can increase their yield under drought conditions by 20-40% compared to untreated ones. This is especially relevant in regions of Europe where water scarcity is a growing problem.

Improved nutrient use efficiency

Biostimulants also improve nutrient use efficiency, meaning plants can absorb and utilize nutrients more effectively. This not only reduces the need for fertilizers but also minimizes the risk of environmental contamination. A study conducted on rice crops showed that applying biostimulants increased nitrogen use efficiency by 30%, resulting in lower environmental impact and reduced costs for farmers.

Increased harvest quality

Biostimulants not only increase yield but also improve the quality of final products, which is crucial for European markets that value sustainability and quality. For example, the use of biostimulants has been observed to increase the sugar and nutrient content in fruits and vegetables, improving their flavor and nutritional value. Studies have indicated that tomatoes treated with biostimulants show a 15-25% increase in soluble solids content, translating into better flavor and market quality.
