Ways to Leverage Biostimulants and Biofertilizers for Sustainable Crop Growth

Biostimulants and biofertilizers are revolutionizing agriculture, offering innovative solutions for sustainable crop production. These eco-friendly inputs not only enhance plant growth and nutrient efficiency but also build resilience against environmental stressors such as drought, heat, and salinity. As farmers navigate the challenges of feeding a growing population while preserving natural resources, biostimulants and biofertilizers are emerging as vital tools for achieving long-term agricultural sustainability.

So what exactly are these tools? BPIA (The Biological Products Industry Alliance) offers good definitions for both types of products.

Biostimulants

Plant biostimulant means a substance, micro-organism, or mixture thereof, that, when applied to seeds, plants, the rhizosphere, soil, or other growth media, act to support a plant’s natural processes independently of the biostimulant’s nutrient content, including by improving nutrient availability, uptake or use efficiency, tolerance to abiotic stress, and consequent growth, development, quality, or yield.

Biofertilizers

The term “biofertilizer” can be used to describe any preparation of biological material, such as living microorganisms, nonliving biological (plant or microbial) residues, or the natural breakdown products thereof, that is intended to enhance nutrient availability, uptake and/or nutrient use efficiency in plants, and soil health. They may be applied as standalone interventions or in combination with fertilizers and soil amendments.

“Biostimulants and biofertilizers play a pivotal role in sustainable crop production by enhancing plant health, improving nutrient uptake, and promoting soil vitality. They enable plants to optimize their genetic potential by stimulating natural processes, fostering better growth, yield, and resilience,” says Dr. Trey Cutts, VP of Commercial Ag Science for Tidal Grow AgriScience.

Both categories of products work through natural processes to improve nutrient uptake, increase crop yields, and support the development of stronger root systems, reducing the need for chemical fertilizers.

“Nutrient use efficiency has become the name of the game when it comes to sustainable crop production,” says Fred Nichols, Chief Marketing Officer for Huma, “It’s all about reducing rates of synthetic fertilizers, which is good for the soil, the crops, and the grower’s pocketbook. And that’s where carbon-based biostimulants shine. They can fast-track regen ag and sustainable crop production. And they have a symbiotic effect with cultural practices, by stimulating and accelerating microbial populations and activity. We’re seeing growers successfully cut rates from 10% to 25%.”
