Microbial biofiltration technology for odour abatement: An introductory review
Odour is a serious complaint associated with waste air emissions that creates nuisance due to its malodorous behaviour. Its treatment process ranges from physical, chemical to biological means. A biological treatment system has several advantages over the physical and chemical technologies in being ecofriendly, more efficient with low operational cost and characterized by high flow rates of waste gas with low...

Preparing of the soil salinity map using geostatistics method in the Qazvin Plain
In land evaluation, soil salinity is a limiting factor of plant growth in most suitable land systems. In order to prepare map salinity of south Qazvin Plain with sampling topsoil sample of 0 to 30 cm, electrical conductivity (EC), clay and pH of soil samples were measured. Finally, to provide the salinity map of topsoil, the accuracy of the several common methods of interpolation including Kriging, CoKriging,...

Response of maize to different organic and inorganic fertilization regimes in monocrop and intercrop systems in a Sub-Saharan Africa Region
Soil fertility decline is a major constraint to crop production in sub-Saharan Africa due to continuous cropping of maize without an adequate fertilization. The main objective of the present study was to evaluate the effectiveness of several fertilization regimes in monocrop and intercrop systems in a Sub-Saharan Africa region. The study was carried out in a savannah region in D.R. Congo at two locations. The...

Evaluating sustainable cropping sequences with cassava and three grain legume crops: Effects on soil fertility and maize yields in the semi-deciduous forest zone of Ghana
Declining soil fertility has become a major constraint to crop productivity in the semi-deciduous forest agro-ecological zone of Ghana. We evaluated six crop sequences: pigeonpea, cassava variety ‘Ex-Subi’, cassava variety ‘Boakentemma’, cowpea-maize, groundnut-maize and maize-maize in 2007/2008 and 2008/2009 cropping seasons to determine their effects on soil chemical properties and...
