Biochar-based organic fertilizer application promotes the alleviation of tobacco (Nicotiana tabacum L.) continuous cropping obstacles by improving soil chemical properties and microbial community structure.

ABSTRACT:

Background

Intensive monoculture poses a serious threat to agricultural sustainable development due to the phenomenon of continuous cropping obstacles. Although organic amendment has been considered an efficient and environmentally friendly solution to mitigate this tough issue, the associated mechanisms remain poorly understood. Here, a two-year field experiment was conducted with the application of four fertilizers, wood, rice straw, compound biochar-based organic fertilizers (WBF, RBF, CBF) and chemical fertilizer (CF) under tobacco rotation with broad bean and oilseed rape, respectively. This work aims to determine how BFs application alleviates tobacco CCO and to further reveal the underlying action mechanisms primarily focusing on the change of soil micro-ecology environments
