Abstract
The protracted and immoderate utilization of chemical fertilizers has been detrimental to the composition of fungi in the soil and quality of crops. To ameliorate the adverse effects, a 6-year positioning experiment was undertaken to investigate the impact of substituting 0 % (CF), 25 % (M25), 50 % (M50), 75 % (M75), and 100 % (M100) of 225 kg ha-1 chemical fertilizer nitrogen with manure nitrogen on both soil fungi and maize quality. This study showed that the expansion of Aspergillus heterocaryoticus, Xerochrysium dermatitidis, and Aspergillus penicillioides contributed to heightened levels of amylose and soluble sugars. The proliferation of Botryotrichum domesticum impeded the biosynthesis of amylose. Enhanced abundances of Erysiphe paeoniae and Fusarium asiaticum hindered the biosynthesis of soluble sugar, whereas the increase in Aspergillus flavus, Monascus pilosus, Xerochrysium xerophilum, and Wickerhamomyces anomalus increased the biosynthesis of soluble sugars. Sordariomycetes, Dothideomycetes, and Eurotiomycetes were the predominant classes. M50 significantly increased the relative abundance of populations of fungal parasites by 100.03 % and 219.82 % compared to CF and M00, respectively. Venturiales was the singular order of fungi exclusive to CF. Trichothecium roseum, Papiliotrema flavescens, and Paraisaria phuwiangensis emerged as distinguishing biomarkers for CF, M25, and M75, respectively. Papiliotrema flavescens could be utilized in the classification of samples.
