Biomass briquettes are a biofuel substitute to coal and charcoal. They are used to heat industrial boilers in order to produce electricity from steam. The most common use of the briquettes are in the developing world, where energy sources are not as widely available. There has been a move to the use of briquettes in the developed world through the use of cofiring, when the briquettes are combined with coal in order to create the heat supplied to the boiler.
Optimum nitrogen rates and methods of application increase crop productivity and farm income while reducing negative environmental effects. Field experiments were conducted during four consecutive rice growing seasons in 2012–2013 to determine the effects of different N rates and methods of fertilizer application on floodwater ammonium concentration, rice yields and N use efficiency under two water regimes: continuous standing water and alternate wetting and drying (AWD).
