    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).

    Crunched the quantities on the hay, and as your attached file shows, the tons produced via forage (haylage) is not proportionate to number of farms/acres. Elko's actual percentage of state production is 12.5%.
