主　　题：animal feed crop residue electricity generation soil enhancement 

摘      要：Many studies have estimated the potential of crop residues for energy generation globally and recognized its great potential,especially in rural areas where on-grid electricity is ***,crop residues have other equally important uses as animal feed and as mulch for soil enhancement,especially in rural farming ***,most of the known studies have neglected the estimation of the quantity of crop residues that will be required for feeding animals and also for the enhancement of soil through mulching in their energy potential estimation from crop *** these two important uses can lead to the over-exploitation of the residues for energy generation at the expense of conservation agriculture practices as well as depriving animals of quality feed which can lead to low crop yield and animal production,with the ability to cause hunger and *** study has assessed the potential of electricity generation from agricultural residues in the Sawla-Tuna-Kalba district of Ghana using gasification technology,taking cognizance of the proportion of residues needed for animal consumption and soil *** results of the study indicate that out of the 207646.22 t of residues that can be generated from maize,yam,cassava,millet,sorghum,and groundnut,26830.36 t(representing 13%)will be required by sheep,goats,and cows for consumption,and 13936.17 t(representing 7%)will be required for mulching soils where the crops are ***,it was found that a total of 592.17 MW∙h of electricity can be generated from crop residues without animal consumption and soil enhancement needs,while 461.89 MW∙h could be generated from the residues,considering animal feed and soil *** study has indicated that it is not enough to consider soil enhancement and animal feeding in agricultural biomass power generation through recovery factors without the exact quantification of residues required for these purposes since this can lead to a vi
