Long-term organic fertilizer and biofertilizer application strengthens the associations between soil quality index, network complexity, and walnut yield

Although various combinations of organic-inorganic fertilizers can enhance plant yields, the effects of different fertilization regimes on the associations between rhizosphere soil microorganisms and plant productivity are poorly understood. In this study, we investigated the rhizosphere soil microb...

Description
Summary:Although various combinations of organic-inorganic fertilizers can enhance plant yields, the effects of different fertilization regimes on the associations between rhizosphere soil microorganisms and plant productivity are poorly understood. In this study, we investigated the rhizosphere soil microbial composition and structure and the relationships among rhizospheric microorganisms, soil properties, and yield in a walnut (Juglans regia L.) orchard after 7 years of applying different fertilization regimes. The combinations of organic and inorganic fertilizers were found to enhance walnut yield, soil quality index (SQI), and soil biodiversity (bacterial and fungal) (P
