2009 Data, Hay in Wyoming
[attachment:1]C:\fakepath\Sector10WY.xlsx[/attachment]
Here's a question I just received. I suspect it's a data issue. Could you check for me please?
"Attached is a spreadsheet with the Wyoming Counties that the IMPLAN 2009 data shows no production for Sector 10 – All Other Crop Farming. This is a concern since I think this sector is where hay production is located and most of these counties have at least some hay production."
My correspondent adds that even in the counties where production in sector 10 shows up, it seems only to reflect the production of crops other than hay, judging by the TIO.

The source of distribution hay production by county comes from 2007 Census of agriculture and comes from the census tables noted below: All hay tons dry 2-27-230 col1 (farms) col2 (acres) col3 (count) All haylage tons dry forage 2-1-110 (farms) 2-1-111 (acres) 2-1-112 (count) This is used only for distribution of the state value from NASS. NASS data only reports sales; however, we have a blowup factor (3-4) to convert sales to total hay production. The majority of hay seems to be produced on-farm use. We only have one factor for the US as a whole. The total Hay Sales from NASS for WY in 2009 was $66.7 million (there is relatively little other crop -sector 10 in WY). In IMPLAN the total for Sector 10 was $272 million. I would have to check into the original Census data and our programming to see if Hay/Haylage was missed for some of the WY counties. The WY counties with sector 10, do sum to $272 million. -
I've got a related hay issue in Elko Co. Nevada. IMPLAN 2007 had a hay sector with about $73 million in output. In 2008 and 2009 the hay sector has zero output. When I look at the Census of Ag I don't see a huge change between 2002 and 2007 in hay production there. Any changes in methodology that would account for this? http://www.agcensus.usda.gov/Publications/2007/Full_Report/Volume_1,_Chapter_2_County_Level/Nevada/st32_2_027_028.pdf -
You are corect. It appears that only the NV counties that were disclosed received hay production. Non-diclosed counties were supposed to have received a portion of the state production based on state average production per acre, but instead are 0. Thank you for pointing this out. Elko production of sector 10 should be ~1/4 of the state production. If your study needs this sector introduce it to the study area data (use 1/4 state values), also edit the RSC such that demand uses local hay (ie, set local use of local supply = to local supply for commodity 10).
