Moldova is a country with very few natural resources that may contribute to improving its economy. One of these resources is a fertile soil. If used properly it could bring great benefits to the Republic. Sadly, the current agricultural practices are far from being sustainable and provoke high rates of soil degradation and pollution. The purpose of this work was to study the toxic impacts of soil pollution by trifluralin on soybean, alfalfa and maize, as well as the possibility of overcoming those impacts with the help of Fe3O4 nanoparticles and rhizobacteria. The obtained results are presented in tab. 1 and 2. Conclusion Soil treatment with trifluralin had toxic effects on plant growth. The introduction of Fe3O4 nanoparticles and rhizobacteria tended to neutralize the negative effect from trifluralin on maize, however their impact was statistically insignificant.
