Fertilization altered co-occurrence patterns and microbial assembly …
AbstractAmmonia-oxidizing archaea and bacteria (AOA and AOB, respectively) are important intermediate links in the nitrogen cycle. Apart from the AOA and AOB communities in soil, we further investigated co-occurrence patterns and microbial assembly processes subjected to inorganic and organic fertilizer treatments for over 35 years. The amoA copy numbers and AOA and AOB communities were found […]

The applicability of biochar and zero-valent iron for the mitigation of arsenic and cadmium contamination in an alkaline paddy soil
Abstract In paddy fields, the opposing transformation of arsenic (As) and cadmium (Cd) poses many challenges for their simultaneous remediation. In our previous study, we reported that combined biochar and zero-valent iron (ZVI) amendment had great potential for the simultaneous alleviation of As and Cd bioavailability in contaminated acid paddy soil. In this study, an […]

Biochar compost blends facilitate switchgrass growth in mine soils by reducing Cd and Zn bioavailability
Abstract Biochars have the potential to reclaim mine-impacted soils; however, their variable physico-chemical properties incite speculation about their successful remediation performance. This investigation examined the capability of biochars produced from three different feedstocks along with a compost blend to improve switchgrass growth conditions in a mine-impacted soil by examining influences on soil pH, grass metal […]
