Abstract Evaluation of in situ capping with biochar (BC) to control ammonia nitrogen (NH 4+-
N) release from the sediments of Baiyangdian Lake, the largest freshwater lake in northern …

The effects of reduced nitrogen release from sediments were studied using biochar (BC)
capping in simulated water–sediment systems. Dried solid waste of Phyllostachys …

Inorganic forms of N from sediments and runoff water, among others, remain some of the key
sources of pollution of water bodies. However, the release of NH 4+-N from sediment to …

Biological removal of the nitrate, a highly concerning contaminant in rivers, is limited due to
the low activity of denitrifying community. Biochar is extensively used in facilitating the nitrate …

Purpose The use of excessive nitrogen (N) fertilizers usually causes soil N leaching,
eutrophication, and water pollution. Nevertheless, biochars may play an important role in …

Denitrification and NH 3 volatilization are the main removal processes of nitrogen in coastal
saline soils. In this incubation study, the effects of wheat straw biochar application at rates of …

Biochar can play a key role in nutrient cycling, potentially affecting nitrogen retention when
applied to soils. In this project, laboratory experiments were conducted to investigate the …

Biochar has been extensively demonstrated as an abundant, cost-effective, and highly
efficient adsorbent material for removing ammonium (NH 4+) from non-point source-polluted …

Mangrove biochar residue was used for nitrogen adsorption and retention in sediment,
which is beneficial for plant germination. The present study investigated the effect of contact …

The limitations of the existing means of treating brewers' spent grain and sewage sludge
highlight the need to find sustainable routes to manage them. Biochars derived from their …
