Biostimulants

Understanding Biostimulants and Their Role in Agriculture

Biostimulants are an essential component of modern agriculture, designed to enhance plant growth and productivity by influencing the plant’s physiological processes. These substances or organisms, when applied to crops, can significantly boost the efficiency of nutrient uptake and utilization, improve stress tolerance, and enhance overall plant quality.

What is a Biostimulant?

A biostimulant is any natural or synthetic substance or microorganism that, when applied to plants, activates various molecular, physiological, and biochemical processes within the plant. These processes can include:

• Enhanced Nutrient Uptake: Biostimulants help plants absorb more nutrients from the soil, leading to better growth and higher yields.
• Increased Nutrient Use Efficiency: By improving how efficiently plants use the nutrients they absorb, biostimulants help reduce the need for additional fertilisers.
• Improved Stress Tolerance: Biostimulants can help plants withstand environmental stresses such as heat, drought, and salinity by boosting their natural defence mechanisms.
• Promotion of Root Growth: Stronger root systems allow plants to access water and nutrients more effectively.
• Enhanced Plant Quality Traits: Biostimulants can improve various quality aspects of crops, such as size, colour, and nutritional content.

Frequently Asked Questions (FAQs) About Biostimulants

1. What are the main differences between biostimulants and fertilisers?

• Fertilisers provide essential nutrients like nitrogen, phosphorus, and potassium directly to plants, while biostimulants enhance the plant’s ability to absorb and utilise these nutrients more efficiently. Biostimulants also help plants cope with environmental stresses, something fertilisers alone cannot do.

2. Can biostimulants replace traditional fertilisers?

• Biostimulants are not a replacement for traditional fertilisers but are used in conjunction with them. They improve the effectiveness of fertilisers by enhancing nutrient uptake and utilisation, which can lead to reduced fertiliser application over time.

3. How do biostimulants improve stress tolerance in plants?

• Biostimulants trigger physiological responses in plants that strengthen their natural defence mechanisms against stressors such as heat, drought, and salinity. This includes the production of stress inhibitors and the enhancement of root systems to access water and nutrients more efficiently.

4. Are biostimulants safe for all types of crops?

• Yes, biostimulants are generally safe for a wide range of crops, including fruits, vegetables, cereals, and ornamental plants. However, it is essential to choose a biostimulant that is specifically formulated for the crop type you are cultivating.

5. How should biostimulants be applied?

•  Biostimulants can be applied in various ways, including foliar sprays, soil treatments, and seed coatings. The application method depends on the specific product and the crop being treated. Always follow the manufacturer’s instructions for the best results.

6. How soon can I expect to see results after applying biostimulants?

• The effects of biostimulants can vary depending on the crop type, environmental conditions, and the specific product used. In general, improvements in plant growth and stress tolerance may be observed within a few weeks of application.

7. Can biostimulants be used in organic farming?

• Many biostimulants are compatible with organic farming practices. However, it is important to check the product label or consult with the manufacturer to ensure that the biostimulant meets organic certification standards.

8. What are the environmental benefits of using biostimulants?

•  By improving nutrient use efficiency, biostimulants can reduce the need for chemical fertilisers, which helps minimise nutrient runoff into water bodies and reduces the environmental impact of agriculture. Additionally, biostimulants can help crops cope with climate-related stresses, promoting more sustainable agricultural practices.
