Emissions from stockpiled pond sludge and yard scrapings were compared with composted dairy-manure residues blended with shredded vegetation residues and chicken litter over a 5-month period at a farm in Victoria (Australia). Results showed that methane emissions occurred primarily during the first 30–60 days of stockpiling and composting, with daily emission rates being highest for stockpiled pond sludge. Cumulated methane (CH4) emissions per tonne wet feedstock were highest for stockpiling of pond sludge (969 g CH4/t), followed by composting (682 g CH4/t) and stockpiling of yard scrapings (120 g CH4/t). Sizeable nitrous oxide (N2O) fluxes were observed only when temperatures inside the compost windrow fell below ~45−50°C. Cumulated N2O emissions were highest for composting (159 g N2O/t), followed by stockpiling of pond sludge (103 g N2O/t) and yard scrapings (45 g N2O/t). Adding chicken litter and lime to dairy-manure residues resulted in a very low carbon-to-nitrogen ratio (13 : 1) of the composting mix, and would have brought about significant N2O losses during composting. These field observations suggested that decisions at composting operations, as in many other businesses, are driven more by practical and economic considerations rather than efforts to minimise greenhouse-gas emissions. Total greenhouse-gas emissions (CH4 + N2O), expressed as CO2-e per tonne wet feedstock, were highest for composting (64.4 kg), followed by those for stockpiling of pond sludge (54.5 kg) and yard scraping (16.3 kg). This meant that emissions for composting and stockpiling of pond sludge exceeded the new Australian default emission factors for ‘waste composting’ (49 kg). This paper proposes to express greenhouse-gas emissions from secondary manure-management systems (e.g. composting) also as emissions per tonne wet feedstock, so as to align them with the approach taken for ‘waste composting’ and to facilitate the development of emission-reduction methodologies for improved manure management at the farm level.

Until recently, nutrient losses from livestock manure have been of little concern. Manure, a valuable by-product in the past, is now regarded as a waste product to be disposed of in the cheapest manner possible. The cost of manure handling frequently exceeds the value of the nutrients in it. This is still true in 1974 even though the price of fertilizer has increased substantially.

HighlightsCarbon and nitrogen gas emissions from manure storage were influenced by manure characteristics.The main GHG contributor for dairy cattle, beef cattle, and broiler manure was methane.The main GHG contributor for laying hen manure was nitrous oxide (N2O).N2O emissions of the five types of manure were comparable with the IPCC recommended value.Abstract. Livestock manure management is an important source of greenhouse gases (GHGs) and ammonia (NH3) emissions from agriculture. Large amounts of manure are produced in China, while little research is available on the gas emission characteristics from different manure sources. The GHG and NH3 emissions from pig manure (PM), dairy cattle manure (DCM), beef cattle manure (BCM), layer manure (LM), and broiler manure (BM) during storage were monitored using the dynamic emission chamber method to compare the differences in gas emission characteristics among the five manure types and elucidate the key factors causing the differences. The results indicated that C and N gas emissions from manure storage were influenced by manure characteristics. The total CO2-eq (without CO2) emissions from PM, DCM, BCM, LM, BM were, respectively, 49.98 ±3.53, 1160.4 ±55.22, 692.16 ±42.98, 61.99 ±1.92, and 72.52 ±3.45 g per kg of dry basis manure during 77-day storage. The main GHG contributor for DCM, BCM, and BM was methane (CH4), accounting for 65% to 94%, and the main GHG contributor for LM was nitrous oxide (N2O). For PM, CH4 and N2O contributed equally to the total emissions. The N2O emissions of the five manure types were 0.002 to 0.013 kg N2O-N kg-1 N and were comparable with the IPCC recommended value.
