Source: USDA Farm Service Agency, 2026 Acres by County report dated
August 1, 2026; county boundaries and land area from the U.S. Census Bureau.
Ethanol plant locations and capacity are from the U.S. Energy Information
Administration's January 1, 2025 capacity report; points use Census place
locations because EIA reports city and state rather than facility coordinates.
Soybean-capable member facilities are from the National Oilseed Processors
Association's member-location list updated June 18, 2026. Capacity,
transportation, and region fields are cross-referenced to Sheet2 of
csv_data/soybean_crush_margin_analysis/US Soybean Crush June 15
2026.xlsx.
Biodiesel and renewable diesel/other biofuels plant locations and capacities
are from EIA's January 1, 2025 plant-capacity reports. Those reports do not
identify facility-level feedstocks, so these markers show potential
soybean-oil processors rather than confirmed soybean-oil users.

Planted acres include all FSA crop types, intended uses, and irrigation
practices for corn and soybeans. Wheat maps show the exact FSA Hard Red
Winter, Soft Red Winter, and Hard Red Spring crop types. White Wheat combines
Hard White Spring, Hard White Winter, Soft White Spring, and Soft White
Winter. Canola, barley, and oats include every FSA crop type and intended
use under those crop names. Peanuts uses the FSA Peanuts crop and excludes
Perennial Peanuts. Cotton combines ELS and upland cotton labels. Failed and
prevented acres are not included. Each county is shaded by a combined
score: the geometric mean of its percentile for actual crop acres and its
percentile for the crop's share of all planted acres in that county. The
red dots on the Corn tab are EIA-listed fuel ethanol plants; hover for the
operator, reported location, and annual and daily production capacity. The
blue dots on the Soybeans tab are NOPA member facilities categorized as
soybean or dual-purpose soybean/softseed plants; softseed-only facilities
are excluded. Hover for the operator, location, processing category,
estimated crush capacity, rail service, and shuttle status. Combined
capacity rows for Decatur, Illinois and Quincy, Illinois are each displayed
as one combined plant marker and labeled as covering two facilities. The
Sheet2-only Mitchell, South Dakota
plant is included and identified as absent from the current NOPA list.
Purple markers identify the six plants tagged X in Sheet2's
River Tributary column; Deerfield's uncertain ? tag remains
the standard blue and is identified as uncertain in its tooltip. Orange
dots on the Soybeans tab are EIA-listed biodiesel plants. Red dots are
EIA-listed renewable diesel and other biofuels plants, including refineries
that co-process renewable feedstock and petroleum. EIA does not report
plant-level feedstocks, so neither marker confirms current soybean oil use.
Hover for operator, reported location, fuel category, and annual and daily
production capacity. The Hawaii biodiesel plant is included in the
reference but lies outside the map's fitted lower-48 extent. The map uses
only committed Census county geometry and does not load an external
basemap or mapping API.
