Bisphenol S Adsorption Behavior on Ferralsol and Biochar Modified Soil with Dissolved Organic Matter
Biochar effects on soil microbial abundance and community structure are keys for understanding the biogeochemical cycling of nutrients and organic matter turnover, but are poorly understood, in particular in tropical areas. We conducted a greenhouse experiment in which we added biochars produced from four different feedstocks [sewage sludge (B1), deinking sewage sludge (B2), Miscanthus (B3) and...
Agricultural soils are the primary anthropogenic source of atmospheric nitrous oxide (N2O), contributing to global warming and depletion of stratospheric ozone. Biochar addition has shown potential to lower soil N2O emission, with the mechanisms remaining unclear. We incubated eucalypt biochar (550 °C)--0, 1 and 5% (w/w) in Ferralsol at 3 water regimes (12, 39 and 54% WFPS)--in a soil column, f...
ABSTRACT In the Brazilian Savanna, most of soils have a low natural fertility. order to overcome this limitation, farmers use large amounts soluble fertilizers, causing environmental impacts. present study, finely ground biotite syenite (0; 600; 1,200; 1,800; and 2,400 kg ha-1) was evaluated as an alternative source nutrients electrical charges in weathered Ferralsol from Savanna. Additionally,...
This incubation trial was carried out to determine the effect of urea amendment cocoa pods husk (CP) and coffee wastes (CW) on their ability improve some physico-chemical properties potassium availability in a Ferralsol Western region Cameroon. It conducted using completely randomized design consisting seven treatments three replications. Modalities included doses (0; 0.003 0.006g per 100g dry ...
