Agricultural commodity statistics 2012.
The most suitable dataset is the ABARE-BRS (2010) National Land Use of Australia version 4 (2005-6) available at http://www.daff.gov.au/abares/aclump/pages/land-use/data-download.aspx. You can still have N stress but it is due to lack of soil water where the soil nitrogen is plentiful. Compared to Midwestern America and Europe, only one tenth to half the amount of fertilizer and agrichemicals are used per hectare of cropland (Price 2006). Informa Markets, a trading division of Informa PLC.
In those years, total national wheat production … On average 61% was cropped, 33% was maintained as pasture and 5% was reported as native vegetation.
For example, corn yields in 2004 were +17 bushels above trend. We have different commercial license types available, either for a single use of the data within a project context or multiple use and commercialization, suiting your needs. BoM (2009). A survey of farm practices with 1312 grain producers found that in 2011, the average farm size was 3810 ha.

Daily solar radiation is recorded at relatively few stations, and was sourced as interpolated data for both primary and secondary stations. New staffer, a hurricane challenge and an immigrant story, Afternoon Market Recap for Sept. 25, 2020, Next Generation Fuels Act introduced in House.
(2003). Globally, Australian wheat averaged approximately 3.5% of world production over the same period, and 12.1% of global wheat exports (2005-2012). https://www.farmprogress.com/sites/all/themes/penton_subtheme_farmprogress/images/logos/footer.png. Toowoomba QLD 4350 While it required about 5.9 ha to feed one person, one unit of agricultural labour (counting farmers plus their employees) annually feeds about 109 people. Australian Soil Classifications (ACLEP, 2012) were used as the basis for crop yield simulations, and Soil Taxonomy Order equivalents are provided for comparison. Birds may be a problem at both seeding and harvesting time, while raccoons are fond of the ripening ears.
Making a simplifying assumption that wheat comprised a fixed proportion (59.79%) of cereal cropping over the entire mapped cereals area, those areas were adjusted to the 2005/6 wheat area of 12,443,000 ha (ABARES, 2012). Historically, yields 10 bushels above trend, or higher, have occurred eight times (14% of the time). Additionally, to ensure that abundant soil nitrate was available, soil N levels were reset at the start of each day. 2. For Kyancutta, where average Yw values were much lower than the Ya values, we re-calculated Yw by replacing the Kyancutta meteorological data with data from Warramboo, about 14 km away and well within the RWS buffer zone. Outside of the trend yield, it is important to consider the full range of possible yields. Isbell, R. F. (1996).
In addition data for 2562 Patched Point Dataset (PPD) sites were used as secondary meteorological stations. An overview of APSIM, a model designed for farming systems simulation. Australia is known for a variable climate and highly variable rainfall which results in substantial variation in wheat yields. That year corn yields were a record-shattering 160 bushels per acre. Even though flipping numerous consecutive “heads” is a low probability event, each flip is independent of the previous flips and a 50:50 odds.
