Application of low dosage of copper oxide and zinc oxide nanoparticles boosts bacterial and fungal communities in soil

With the expanding nanotechnology, nanoparticles (NPs) embedded products are used in agricultural sector to improve soil fertility. Thus, two typical metal oxides NPs and their mixtures were applied different doses evaluate impacts on microbes. CuO ZnO boosted microbial communities as reflected by increased number of extractable bacterial or fungal groups enlarged values Chao 1, ACE, Shannon indices. Relative abundance some susceptible taxa such Sphingomonadales with increasing concentrations NPs, while IMCC26256 decreased NPs. The mixture did not show more promotional effects community than sum individual effects. Increased organic carbon mitigated bacteria for but As micro-nutrients, ions released from had potential promote richness diversity. However, positive MNPs impaired at dosage higher 250 mg kg ?1 (213.08 Cu, 162.73 Zn). application dose type other coexistence should be considered before wide use productivity. • Both promoted Positive microbes high concentrations. Particulate dissolved forms explained showed no additional benefits impact was affected environmental factors.
