Abstract

Nanofertilizer is an innovative solution to soil and crop degradation due to excessive use of conventional fertilizers. It exhibits an alternative potentiality since its integrative nutrient-element nanoparticles allows for efficient delivery of nutrients to crops. However, there is a scarcity of research evaluating its consequential effects on soil microbial taxa. This study examines the response of fungal communities after the application of conventional fertilizer and nanofertilizer in a sugarcane field using Amplicon-based metagenome analysis. The findings show Ascomycota, Basidiomycota, and Mortierellomycota as the dominant phyla, along with their corresponding classes. The relative abundance of Ascomycota initially decreased after application of treatments (DAY 01) but recovered at DAY 07. Differential response was observed in the relative abundance of fungal phylum Basidiomycota which responded positively with the conventional fertilizer treatment but was unaffected by nanofertilizer treatment. PCoA revealed the greater influence of time on fungal composition than fertilizer treatments. These results suggest that the application of soil amendments, whether conventional fertilizer or nanofertilizer, has an effect on fungal communities in sugarcane soil.
