Recently, the potential for biochar use to recapture excess nutrients from dairy wastewater has been a focus of a growing number of studies. It is suggested that biochar produced from locally available excess biomass can be important in reducing release of excess nutrient elements from agricultural runoff, improving soil productivity, and longterm carbon (C) sequestration. Here we present a rev...

Biochar can influence native soil organic carbon (SOC) mineralisation through "priming effects". However, the long-term direction, persistence and extent of SOC priming by biochar remain uncertain. Using natural (13)C abundance and under controlled laboratory conditions, we show that biochar-stimulated SOC mineralisation ("positive priming") caused a loss of 4 to 44 mg C g(-1) SOC over 2.3 year...

Excessive amounts of animal manures and production a large volume biosolids pose serious environmental issues in terms their safe disposal management. Thermochemical treatment bio-waste materials via pyrolysis can convert them into value-added products such as biochar-based fertilizers. In this study, fourteen biochars were produced from one biosolid thirteen by slow at 300 °C. All feedstock bi...

Gravid mosquito traps are commonly used for both arbovirus surveillance and population surveillance of mosquitoes of the genus Culex. Oviposition substrates, used as baits in these traps, were tested against Culex under laboratory and field conditions. In the laboratory all substrates tested as 1% and 10% dilutions in 2-choice bioassays against female Cx. quinquefasciatus were significantly mor...

vermicompost produced from sugarcane bagasse (sbv) or sawdust (s) were substituted at a range of different concentration in soilless bedding plant container medium, as a peat: vermiculite: perlite (6:3:1), to evaluate their effects on the growth of dieffenbachia amoena in the greenhouse. dieffenbachia amoena was grown in container medium pe: ve: p (6:3:1), in that peat substituted with 0%, 10%,...
