Rhizosphere soil properties may not determine tobacco growth after land consolidation

Understanding the impact of rhizosphere soil properties on tobacco growth after land consolidation is crucial for optimizing agricultural practices. This study investigated the relationship between rhizosphere soil biochemical properties, enzymatic activities, and tobacco growth in three fields in Guizhou province. We found no significant differences in the biochemical properties, soil quality index, or enzymatic activities between tobacco plants exhibiting Good and Bad growth performance. Soil microbial activity was primarily limited by phosphorus, but there were no significant differences in carbon, nitrogen, or phosphorus limitations between the two growth performance. Additionally, soil ecosystem multifunctionality showed no significant correlation with tobacco plant performance. These results suggest that while rhizosphere soil properties play a role, other factors such as microbial communities and management practices may have a more significant influence on tobacco growth after land consolidation. Further research is needed to explore these complex interactions and develop strategies to enhance tobacco production in post-consolidation environments.
