A new study in International Microbiology highlights the potential of native Trichoderma isolates as effective biofertilizers, reinforcing ASTER’s focus on sustainable crop management.
Researchers screened fifteen Trichoderma spp. strains from olive rhizosphere soils for traits linked to plant growth promotion, including production of phytohormones and metabolites such as siderophores, phosphatases, ammonia, and key hormones like indole‑3‑acetic acid (IAA) and gibberellic acid.
Results demonstrated that several isolates exhibit strong plant‑growth‑promoting attributes. In particular, one Trichoderma harzianum strain showed high phytohormone synthesis and enzymatic activity, suggesting promising use as a biofertilizer to enhance plant nutrition and growth in sustainable agriculture systems.
These findings support ASTER’s commitment to reducing dependence on synthetic fertilizers and promoting biological solutions that contribute to soil health, nutrient cycling, and improved crop performance. By harnessing beneficial soil microbes like Trichoderma, Mediterranean production systems—including tomato cropping—can gain resilience while minimizing environmental impact.
