The Effects of Long-term Application of Different Nitrogen Fertilizers on Brown Soil Fertility Indexes and Fungal Communities

Soil fungi play a crucial role in soil microbes,with nitrogen being the primary constraint on plant development.Utilizing nitrogen fertilizer markedly alters the composition and variety of soil fungi communities. This study aimed to investigate the relationship between the composition of soil fungi communities,fertility index,and the structure of soil fungal communities under varying nitrogen fertilizer conditions.
