Layer: NSW Poultry Manure (SA4) (ID: 6)

Name: NSW Poultry Manure (SA4)

Display Field: REGION_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset estimates the mass in dry tonnes (wet tonnes also given) of poultry manure and bedding residues potentially available across NSW, Australia. This information has been collated for the Australian Biomass for Bioenergy Assessment (ABBA) project and will be available for use on the Australian Renewable Energy Mapping Infrastructure (AREMI) platform, to build a national map to service the renewable energy sector. The boundary features were extracted from the Australian Bureau of Statistics (ABS) Australian Statistical Geography Standard (ASGS) digital boundaries [Copyright Commonwealth of Australia administered by the ABS]. This dataset is mapped at the Statistical Area Level 4 (SA4). Each SA4 region shows the average annual poultry manure and bedding residues for the period July 2010 to June 2015 (average of 5 years). The SA4 residues were calculated using data from the ABS ASGS Agricultural Commodities, Australia, cat. no. 7121.0 data cubes and from research carried out by the NSW Forest Science unit, Department of Primary Industries - Forestry. The residues were calculated for each ABS class of poultry as follows: Layer chickens, Meat chickens and All other (ducks, turkeys, other - classed as Meat chickens in this dataset). Assumptions were made as detailed data at the farm scale was unavailable to determine the regional breakdown of percentage of farms that are caged, barn or free range. From the literature, assumptions were made as follows. For Layers, approximately 70% of the industry are caged and manure is collected by conveyor belt, therefore no bedding will be calculated, only manure as excreted. For Meat chickens and All other poultry, manure plus bedding will be calculated. Calculations of manure and bedding are based on the following assumptions: most meat chickens are housed in barns; single-batch litter systems are the most common with 5.5 batches/year; for NSW most common bedding depth = 50mm; basic density of bedding material = 410kg/m3 (softwood sawdust and shavings); stocking density = 30-40kg/m2 = 14 birds/m2 (conservative); poultry litter figures may vary +/-20%. For Layers, wet weight (WW), total solids (TS) and volatile solids (VS) were calculated. For Meat chickens and All other, wet weight (WW), total solids (TS), volatile solids (VS), minimum VS (-20%) and maximum VS (+20%) were calculated. When all calculations were complete for an SA4 region, the class totals were added together to give an overall Total WW, Total TS, Total VS, Min VS and Max VS manure and bedding residues for each SA4 region.
