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 […]

Though public awareness is low, some scientists believe “biochar” is quietly becoming the world’s first major carbon removal success story. The waste coffee husks that come out of Synergie Nord Sud (SNS), Cameroon’s largest coffee-processing plant, are no longer left to gradually decompose in a landfill. Instead, these tons of biomass are now transported to […]

‘No question’ a big trend is growing your own vegetables, nursery owner Perry Grobe says CBC News · Posted: May 20, 2023 9:00 AM EDT | Last Updated: May 20 Person using trowel to lift orange marigold plant out of pot. Other flowers are seen in pots in background. The May long weekend is often […]

Abstract The influence of biochar-released dissolved organic matter (BDOM) on the transcription of gene (DEG) in Pseudomonas stutzeri and Shewanella putrefacien during sulfamethoxazole (SMX) and chloramphenicol (CAP) biodegradation under visible light was investigated in this study. The results indicated that BDOM components would be nutrients for bacterial amplification and growth under the culture conditions of xenon lamp irradiation and […]

Abstract Dissolved organic matter plays a critical role in affecting sorption properties of biochar for organic contaminants. In this study, dissolved humic acid (DHA) as a representative of dissolved organic matter and oak sawdust-derived biochar as a sorbent were prepared and characterized. Roles of DHA in sorption of benzotriazole (BTA), an emerging organic contaminant, to […]

Abstract In recent years, due to the broad application of biochars, the preparation, environmental behavior and aging processes of biochars have attracted wide attention globally, especially the modification of biochars. However, most of the studies only consider the improvement of biochar properties right after the modification, but neglect a complete evaluation of the long-term stability […]
