AbstractBiochar (BC) has exhibited a great potential to remove water
contaminants due to its wide availability of raw materials, high surface area,
developed pore structure, and low cost. However, the application of BC for water
remediation has many limitations. Driven by the intense desire of overcoming
unfavorable factors, a growing number of researchers have carried out to produce
BC-based comp... hiện toàn bộ

AbstractIn recent years, numerous investigations have explored the use of
biochar for the removal of organic and inorganic pollutants in single component
systems. Biochar is a carbonaceous material produced from waste biomass, mainly
by thermochemical conversion methods. This material was used as a biosorbent in
various removal processes of pollutants, and its efficiency was strongly
influenced by... hiện toàn bộ

AbstractBiochars can improve soil health but have been widely shown to reduce
plant-available nitrogen (N) owing to their high carbon (C) content, which
stimulates microbial N-immobilization. However, because biochars contain large
amounts of C that are not microbially available, their total elemental C:N ratio
does not correspond well with impacts on soil N. We hypothesized that impacts on
soil p... hiện toàn bộ
Moderate sewage sludge biochar application on alkaline soil for corn growth: a field study - 2021

AbstractIn view of the risks induced by the inhibitory effects of applying
impracticably large amounts of sewage sludge biochar (SSB) to the alkaline soil,
this field study investigated the influence of moderate biochar amendments (0,
1500, 4500, and 9000 kg/hm2) on corn growth, alkaline soil properties, and the
uptake of potentially toxic elements (PTEs). The results showed that applying
more SSB... hiện toàn bộ
