The search for sustainable agriculture has led to innovative approaches to improve crop flexibility, productivity and nutritional quality. Among these, the distinction between biostimulants and fertilizers has become increasingly significant. PhD. Eduardo Cancellier, offers a comprehensive overview of the emerging field of biostimulants and their critical role in the new normal of agriculture.

Understanding biostimulants and fertilizers

Biostimulants are a diverse group of substances and microorganisms that improve plant growth, nutrition and tolerance to abiotic stress without being direct sources of nutrients. They work through different mechanisms, such as improving nutritional efficiency, improving physiological processes or promoting beneficial microbial activity in the rhizosphere.

In contrast, fertilizers are chemical or organic substances added to soil or plants, mainly to provide essential nutrients for the plant’s growth cycle. Traditional fertilizers focus on supplying all macro and micronutrients, such as nitrogen (N), phosphorus (P), potassium (K) the main macronutrients required by plants.

Biostimulants versus fertilizers: a comparative analysis

  • Mechanism of Action: Biostimulants work by improving the plant’s inherent abilities to absorb nutrients, resist abiotic stresses and improve overall health. Fertilizers, on the other hand, provide the nutrients directly to the plant.
  • Composition: Biostimulants consist of a variety of organic substances and beneficial microorganisms. Fertilizers are mainly composed of chemical compounds that contain specific nutrients.
  • Impact on the environment: Biostimulants are generally considered more environmentally friendly, reducing the need for chemical inputs and promoting sustainable agricultural practices. The improper use of fertilizers, especially in excessive amounts, may lead to damage to the soil, water pollution and imbalance of the ecosystem.
  • Economic benefits: While both biostimulants and fertilizers contribute to increased crop yields, biostimulants offer the added benefit of improving crop quality and resilience beyond levels delivered by fertilizers, which can lead to higher economic returns in the long run.

The future of agriculture with biostimulants

Biostimulants, an innovative approach to crop management, focusing on improving the natural processes of the plant. Unlike traditional fertilizers, biostimulants offer a sustainable route to improving crop productivity, resilience and quality. As the agricultural industry continues to evolve, the incorporation of biostimulants into farming practices promises to play a key role in shaping a more sustainable and productive future.
