Researchers discover key to improved crop performance with microbial biofertilizers and algae-based biostimulants

A study conducted by researchers at the University of Ferrara, Italy, has achieved a significant breakthrough in organic tomato cultivation through the use of microbial biofertilizers and algae-based biostimulants. Published in the Journal of the Science of Food and Agriculture, the research demonstrates notable improvements in both the yield and quality of tomatoes.

The field trials, carried out at the F.lli Baretta farm in Ferrara, utilized plant growth-promoting microorganisms (PGPMs) and natural algae-derived treatments. These methods not only enhance crop resilience against environmental stresses like drought but also bolster plant health and nutrient absorption.

Emanuele Radicetti, an associate professor at the University of Ferrara and the study’s corresponding author, emphasized the urgency of adopting sustainable agricultural practices. “Biofertilizers are emerging as a viable, nature-based solution that reduces the need for external inputs by improving interactions within agroecosystems,” Radicetti stated.

The research highlighted that PGPMs significantly boost root development and shoot biomass, which are critical during the early growth stages of tomato plants. The optimal results were achieved with a combination of the PGPM product MYCOUP and a 1.0% concentration of algae-based biostimulant, yielding up to 67.2 tons per hectare.

“This approach not only supports plant development under normal conditions but also under increased environmental stresses brought on by climate change,” added Radicetti.

The success of these biofertilizers and biostimulants presents a promising path forward for enhancing sustainability in farming. The team at the University of Ferrara plans to continue their research, particularly under drought conditions, and explore the integration of other eco-friendly farming techniques.

The findings are expected to influence future agricultural practices and innovations, particularly in organic and sustainable farming sectors.
