Comparison of bacterial and archaeal communities in two fertilizer doses and soil compartments under continuous cultivation system of garlic.

Soil microbial communities are affected by interactions between agricultural management (e.g., fertilizer) and soil compartment, but few studies have considered combinations of these factors. We compared the microbial abundance, diversity and community structure in two fertilizer dose (high vs. low...
