Layer: NSW Piggery Manure (SA4) (ID: 4)

Name: NSW Piggery Manure (SA4)

Display Field: REGION_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset estimates the mass in dry tonnes of piggery manure 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 piggery manure 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 pigs as follows: Breeding sows and All other (boars, finishers, gilts, growers, suckers, weaners). From the literature, assumptions were made such as Breeding sows = Gestating sows and All other = 1 Standard Pig Unit (SPU) = Grower pigs. There was no way to determine from the ABS data or the literature what system (deep litter or conventional) was been used at the farm scale, hence bedding could not be calculated. Therefore this dataset only represents manure as excreted. Total solids (TS) and volatile solids (VS) were calculated for each SA4 region. No minimum or maximum manure was calculated as there was not enough detailed information to determine these. When all calculations were complete for an SA4 region, the class totals were added together to give an overall Total TS and Total VS manure residues for each SA4 region.
