Biostimulants in Agriculture: A Sustainable Solution for Maximizing Yield and Quality

What Are Biostimulants?

Biostimulants are substances or microorganisms that, when applied to plants or soil, act as a supportive friend, enhancing nutrient uptake, improving stress tolerance, and boosting crop quality, ultimately helping plants thrive in challenging conditions. Unlike synthetic fertilizers, which offer a direct but often temporary nutrient boost, biostimulants serve as catalysts, triggering a cascade of beneficial physiological changes within the plant that unlock its full potential for sustainable growth, development, and stress tolerance.

The scientific community defines biostimulants as:

"Biostimulants are materials, other than fertilisers, that promote plant growth when applied in low quantities." (Kauffman et al., 2007)

"A plant biostimulant is any substance or microorganism applied to plants with the aim to enhance nutrition efficiency, abiotic stress tolerance and/or crop quality traits, regardless of its nutrients content. By extension, plant biostimulants also designate commercial products containing mixtures of such substances and/or microorganisms." (Patrick du Jardin, 2015)

Types of Biostimulants and How They Work

There are two main types of biostimulants, each working in unique ways:

1) Non-microbial biostimulants:

This category includes seaweed extracts, humic and fulvic acids, protein hydrolysates, amino acids, and other plant-derived substances.

• Seaweed Extracts: Harvested from marine algae, seaweed extracts are a treasure trove of growth hormones, trace elements, and bioactive compounds. They enhance nutrient uptake, stimulate root growth, and fortify plants against environmental stresses. Discover the Power of Seaweed Extract!
• Humic and Fulvic Acids: These organic compounds, derived from decomposed organic matter, act as soil conditioners, improving soil structure, nutrient availability, and root development. They also stimulate essential enzymes in plants, promoting growth and stress resistance. Don't Let Your Soil Suffer – Explore the Benefits of Humic and Fulvic Acids!
• Protein Hydrolysates: Derived from plant or animal proteins, these provide readily available building blocks for plant growth and development.
• Amino Acids: Essential for plant metabolism and hormone production, amino acids contribute to overall plant health and stress response. Maximize Your Harvest Naturally with Amino Acids - Learn How

2 ) Microbial biostimulants:

 These are beneficial microorganisms, such as plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF).

• PGPR colonize the plant's roots and help to fix nitrogen, solubilize phosphorus, and produce growth-promoting hormones. 
• AMF form a symbiotic relationship with plant roots, extending the plant's reach into the soil and improving nutrient uptake.

The Multifaceted Benefits of Biostimulants

Biostimulants offer a holistic approach to improving plant health and agricultural productivity:

• Enhanced Nutrient Use Efficiency: Biostimulants optimize the way plants absorb and utilize essential nutrients, reducing the need for synthetic fertilizers and minimizing environmental pollution.
• Stress Resilience: Biostimulants help plants cope with various environmental stresses, including drought, salinity, extreme temperatures, and nutrient deficiencies. This is crucial for maintaining crop productivity in the face of climate change.
• Increased Crop Yield: By promoting root growth, photosynthesis, and nutrient uptake, biostimulants unlock the plant's full potential, resulting in higher yields and superior quality produce. A meta-analysis of over a thousand field trials revealed an average yield increase of 17.9% across various biostimulant categories (Li, J., Van Gerrewey, T., and Geelen, D., 2022)
• Improved Crop Quality: Biostimulants can enhance the nutritional value, flavor, and appearance of crops, leading to higher market value and consumer satisfaction. Studies have shown that biostimulants can increase the levels of antioxidants, vitamins, and minerals in crops, making them more nutritious and appealing to consumers.
• Soil Health Enhancement: Certain biostimulants, like humic acids, improve soil structure, water retention, and microbial activity, creating a fertile environment for plant growth and contributing to long-term soil health.
• Sustainable Agriculture: Biostimulants are a cornerstone of sustainable agriculture, offering an environmentally friendly alternative to synthetic agrochemicals. They promote soil health, reduce chemical inputs, and contribute to a more resilient and eco-friendly farming system.

Biostimulants vs. Chemical Fertilizers

Biostimulants and chemical fertilizers are both used to enhance plant growth and crop yield, but they function in different ways and have varying impacts on the environment:

Can Biostimulants Replace Fertilizers in Agriculture?

In short, no.

While biostimulants can enhance nutrient uptake and use efficiency, they don't provide the bulk of nutrients that plants need for growth. This is why they can't completely replace fertilizers. However, using biostimulants alongside fertilizers can lead to more efficient use of nutrients, maximizing their benefits, potentially allowing for reduced fertilizer application rates. The most effective approach is often to integrate biostimulants into a balanced crop nutrition program that includes appropriate use of fertilizers. This integrated approach ensures that plants receive the necessary nutrients while also benefiting from the plant health-promoting effects of biostimulants. 

Choosing the Right Biostimulant Products

Selecting the most suitable biostimulant can be challenging. To make an informed decision, consider these key factors:

• Crop type: Different crops have varying needs and responses to biostimulants.
• Growing conditions: Environmental factors like soil type, climate, and stress levels influence biostimulant efficacy.
• Desired outcomes: Are you looking to improve yield, quality, stress tolerance, or nutrient uptake?

For example, if you're farming in drought-prone areas, biostimulants rich in proline or glycine betaine can bolster your crops' resilience to water stress. On the other hand, if you prioritize nutritional quality, look for products abundant in amino acids.

How to Use Biostimulants Effectively

Maximize your ROI with biostimulants!

Biostimulants offer a unique opportunity to enhance crop yields, resilience, and overall productivity across a wide range of crops, from specialty fruits and vegetables to large-scale row crops and also backyard gardens. By integrating these products strategically into your existing farming or gardening practices, you can achieve cost-effective application and reap the rewards of healthier, more productive crops.

1) "Free Ride" Application Strategies

One key to unlocking this potential lies in integrating biostimulants into existing farming practices. This "free ride" approach leverages current operations, reducing additional costs for growers. For instance, applying biostimulants during planting as an in-furrow or seed treatment can reach all planted acres without incurring additional application costs. Foliar applications alongside herbicides or fungicides also present efficient opportunities, leveraging existing pesticide treatments to deliver biostimulants. For smaller gardens or individual plants, mix the biostimulant with water and apply directly to the soil or foliage.

2) Application Method Considerations

A comprehensive review of biostimulant trials highlights the prevalence of foliar sprays (60%), followed by soil applications (30%) and seed treatments (10%). While foliar applications dominate biostimulant use, the optimal application method and timing depend on several factors:

• Biostimulant Type: Different biostimulants have unique properties and target different plant processes. The composition of the product will dictate whether it's best suited for foliar, soil, or seed application.
• Timing: he plant's developmental phase plays a crucial role in determining when a biostimulant will be most effective. For instance, some biostimulants work best during early growth stages, while others are more effective during flowering or fruit set.
• Intended purpose: Clearly define your goals. Are you aiming to improve nutrient uptake, enhance stress tolerance, or boost yield potential? The desired outcome should guide your choice of application method.

For example, seaweed extract, a versatile biostimulant, demonstrates how application timing and method influence its effects. When applied at planting, it primarily influences soil microbial communities. However, a foliar application during vegetative growth stages may be more effective in activating the plant's internal defense mechanisms against environmental stress. (Sible et al., 2021)

By understanding these factors and carefully selecting the right application method, you can unlock the full potential of biostimulants for all your crops
