In this study, the responses of soil bacterial communities to biochar amendment in different soils were investigated. Biochar amendment had not significantly changed the bacterial richness and diversity in black soil, fluvo-aquic soil and red soil, but shifted all the soil bacterial community structures. Biochar amendment mainly increased the growth of low-abundance bacteria in fluvo-aquic soil and that of high-abundance bacteria in red soil. The most abundant bacterial phylum in black soil and fluvo-aquic soil, Proteobacteria, increased after biochar addition, while Chloroflexi, the most abundant phylum in red soil, decreased after biochar addition. Some bacterial phyla responded consistently to biochar amendment. However, many more bacterial phyla responded differently to biochar amendment in different soils, especially those phyla present at low abundances. Therefore, our study confirmed that the responses of soil bacterial communities to the same biochar were specific to both soil type and bacterial phylum.

Background: Organic fertilizers are safer and more eco-friendly than chemical fertilizers; hence, organic fertilizers can be used to support sustainable farming. The effects of PGPRs are manifold in agriculture, especially in monoculture crops, where the soil needs to be modified to increase germination, yield, and disease resistance. The objective of this study was to assess the effects of PGPRs combined with fertilizer on the yield and productivity of canola.

The conversion of water hyacinth into biochar offers a sustainable solution to mitigate its proliferation and enhances its potential as a soil amendment for agriculture. This study examined the physicochemical properties of water hyacinth biochar (WHBC) and its impact on soil fertility. Water hyacinth (Eichhornia crassipes) was pyrolyzed at 300 °C for 40 minute with restricted airflow (2-3 m/s), producing biochar with desirable properties and a yield of 44.

This study investigated the effects of fine-sized pork bone biochar particles on remediating As-contaminated soil and alleviating associated phytotoxicity to rice in 50-day short-term and 120-day full-life-cycle pot experiments. The addition of micro-nanostructured pork bone biochar (BC) pyrolyzed at 400 and 600 °C (BC400 and BC600) significantly increased the As-treated shoot and root fresh weight by 24.4-77.

Understanding the impact of different soil amendments on microbial communities and antibiotic resistance genes (ARGs) dissemination is crucial for optimizing agricultural practices and mitigating environmental risks. This study investigated the effects of different fertilizer regimes and biochar on plant-associated bacterial communities and ARGs dissemination. The biochar's structural and chemical characteristics were characterized using scanning electron microscopy (SEM) and Fourier-transform infrared (FTIR) spectroscopy, revealing a porous architecture with diverse functional groups.
