Liquid manures stored produce a significant amount of methane (CH4) and ammonia (NH3) gas from biological anaerobic fermentation. Studies carried out to evaluate a potential biological cover on inhibiting gases emission and simple cover design to overcome the high cost of biogas production on covered lagoon types that are available on the market. The agriculture waste from rice straw cocopeat hay and sawdust were used as biological covers in reducing CH4 emission and NH3 volatilisation from ruminant slurries. During ninety days of the undisturbed storage period immediate reduction of CH4 and NH3 gases fluxes were observed after the application. Rice straw and coco peat were found to effectively reduce the emission of CH4 and NH3 between 45.5 and 56.9. Other biological cover showed a slightly lower reduction on NH3 volatilisation and much lower in CH4 inhibition percentage (28-29). Covering method was found to be suitable with Malaysias climate in reducing greenhouse gas emission from slurry manure.

Abstract

Liquid manures stored produce a significant amount of methane (CH4) and ammonia (NH3) gas from biological anaerobic fermentation. Studies carried out to evaluate a potential biological cover on inhibiting gases emission and simple cover design to overcome the high cost of biogas production on covered lagoon types that are available on the market. The agriculture waste from rice straw cocopeat hay and sawdust were used as biological covers in reducing CH4 emission and NH3 volatilisation from ruminant slurries. During ninety days of the undisturbed storage period immediate reduction of CH4 and NH3 gases fluxes were observed after the application. Rice straw and coco peat were found to effectively reduce the emission of CH4 and NH3 between 45.5 and 56.9. Other biological cover showed a slightly lower reduction on NH3 volatilisation and much lower in CH4 inhibition percentage (28-29). Covering method was found to be suitable with Malaysias climate in reducing greenhouse gas emission from slurry manure.
