Crop types have stronger effects on soil microbial communities and functionalities than biochar or fertilizer during two cycles of legume-cereal rotations of dry land

Popis výsledku v původním jazyce

The addition of biochar to agricultural fields has been widely studied, but most of these studies have emphasized its effects by growing a single type of crop over short- to long-term time spans. Additionally, a limited number of studies have focused on the soil microbial community composition with respect to biochar addition in legumecereal crop rotation. In this study, we examined soil microbial community structures by adding biochar (0, 5, and 10 t ha(-1)) and fertilizer (nitrogen-N, phosphorous-P and potassium-K) during 2 cycles of mash bean and wheat rotations. The results showed that the bacterial (16S rRNA) gene abundance was often increased by biochar addition in the presence of mash bean (Vigna mungo L) but not wheat. When the soil received fertilizer, the bacterial gene abundance was less responsive to biochar addition. Fungal (ITS rRNA) copy numbers were enhanced by biochar and fertilizer in presence of wheat but were decreased in the presence of mash bean. Fertilizer addition also resulted in less change in ITS genes after biochar addition. Microbial functional groups including Gram(+), Gram(-) and Pseudomonas bacteria were stimulated by biochar or fertilizer only in mash bean soils, while mycorrhizae were significantly increased by biochar in wheat soils. Although biochar addition affected soil properties, microbial community assays were not greatly altered by these physicochemical properties. In conclusion, the crop type played a decisive role, rather than biochar or fertilizer addition, in shaping microbial community structures (16S and ITS phyla) during crop rotation.
