“…Our study demonstrated that the H' was significantly higher under biochar and manure treatments than under single mineral fertilizer treatment. The increases in soil nematode H' was significantly related to the better soil properties, such as adequate soil moisture and higher organic matter content, as the biochar and manure provided a sufficient food supply and a suitable soil environment for organisms [42,43]. In the current study, the change of channel index (CI) reflected the dominant decomposers under the biochar and manure treatments were bacteria and the dominant decomposers under the CK treatment were fungi.…”

Background: Manure and biochar soil amendments have shown many benefits to soil quality and crop productivity. This study aimed to reveal the effects of biochar and manure applications on soil fertility improvement and crop productivity in yellow cinnamon soil. Results: This study based on a 5-year field experiment. Four treatments were designed, included the control (CK), biochar amendment, manure amendment, and both biochar and manure amendment (BM). The results showed that: after five years, both biochar and manure treatment improved soil structure by increasing soil mean weight diameter (MWD), and soil water and nutrient supply was also increased by increasing the contents of water content, available potassium and available phosphorus. The productivity was also enhanced as wheat yield under the biochar, manure, and BM treatments increased by 3.59-11.32% compared with CK. In addition, biochar and manure treatment increased soil microbial biomass carbon (MBC) by > 15%, and soil total nematode abundance was significantly increased. Furthermore, the nematode community structure was significantly affected by biochar and manure treatment, dominant trophic group in CK was herbivores, but bacterivores were dominant in the biochar and manure treatments. The distribution of nematode genera was closely related to soil chemical properties and microbial biomass. Increases in the Shannon's diversity index, and decreases in the dominance index and summed maturity index after the 5-year treatment indicated a sustainable soil ecosystem after the biochar and manure applications. Conclusions: These findings indicate that biochar and manure result in better soil quality and increased productivity in yellow cinnamon soil.
