Biochar-mediated changes in the microbial communities of rhizosphere soil alter the architecture of maize roots.

ABSTRACT: Aeolian sandy soil is a key resource for supporting food production on a global scale; however, the growth of crops in Aeolian sandy soil is often impaired due to its poor physical properties and lack of nutrients and organic matter. Biochar can be used to enhance the properties of Aeolian sandy soil and create an environment more suitable for crop growth, but the long-term effects of biochar on Aeolian sandy soil and microbial communities need to be clarified. Here, a field experiment was conducted in which biochar was applied to a maize (Zea mays L.) field in a single application at different rates: CK, 0 Mg ha^-1; C1, 15.75 Mg ha^-1; C2, 31.50 Mg ha^-1; C3, 63.00 Mg ha^-1; and C4, 126.00 Mg ha^-1. After 7 years of continuous maize
