Research-grade calculators for grain drying energy, real-time moisture monitoring, post-harvest storage loss, and oilseed quality analysis — grounded in USDA-ARS peer-reviewed science from Micah Lewis, Research Agricultural Engineer at the RRRC, Athens, GA.
Official USDA price received and yield data by commodity, state, and year. Price auto-populates Storage Loss market price (SF20-S.003). Yield provides per-acre quantity reference for drying and storage calculators.

Monthly USDA WASDE forecast — U.S. production, use, ending stocks, and projected season-average price. Use alongside NASS actuals to stress-test storage loss and drying calculations against forecast price scenarios.
Source: USDA FAS PSD Online (WASDE-aligned monthly forecast). Reference data used as fallback.
Side-by-side view of NASS historical actuals versus USDA WASDE forecast. Fetch both sources first, then select a commodity to compare. Use the price difference to run scenario analysis in the economics calculators.
Tip: Use the WASDE forecast price in economics calculators to model best-case / worst-case ROI scenarios alongside the NASS actual.
Calculate energy requirements, drying time, and fuel cost for high-temperature grain drying. Based on USDA-ARS psychrometric equations and grain equilibrium moisture content models.
Determine equilibrium moisture content, safe storage thresholds, and mold risk window based on temperature and relative humidity. Based on USDA-ARS microwave sensing research and Modified Henderson EMC equations.
Estimate dry matter loss, quality degradation, and economic value loss from improper grain storage conditions. Models fungal, respiration, and insect loss pathways based on USDA post-harvest research.
Analyze oilseed quality parameters including oil content, protein content, moisture-adjusted grade, and foreign material dockage. Based on USDA-ARS nondestructive sensing and grading research.
Built on USDA-ARS research from the RRRC, Athens, GA — including Micah Lewis's microwave sensing and grain moisture work as Research Agricultural Engineer — AgrStak's SF20 calculators translate federal grain science into real-time farm decisions. From drying cost optimization to moisture equilibrium analysis, these 4 models support grain farmers, elevator operators, post-harvest specialists, and agricultural researchers. Part of AgrStak's 431-model platform — patent pending.
