Irrigation efficiency modeling, energy audit science, equipment sizing, and grain storage engineering — grounded in USDA ARS agricultural engineering and ASABE research standards.
Official USDA price received and yield data by commodity, state, and year. Price auto-populates Storage Loss market price (SF19-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 irrigation system efficiency, water application uniformity, and deep percolation losses. Based on USDA-ARS NRCS irrigation engineering standards and water use efficiency research.
Audit farm energy consumption across grain handling, irrigation pumping, and HVAC systems. Calculate energy use intensity and identify efficiency improvement opportunities per USDA-ARS energy benchmarks.
Determine optimum equipment width and field capacity for planting, harvest, or tillage operations given acreage, available field days, and timeliness loss coefficients per ASABE/USDA-ARS standards.
Size grain bins or flat storage for on-farm grain storage needs. Calculate required capacity, structural loads, ventilation airflow requirements, and fan sizing per USDA-ARS and ASABE storage engineering standards.
Built on USDA-ARS Agricultural Engineering Research standards — AgrStak SF19 science calculators help farm managers and engineers optimize irrigation efficiency, audit farm energy use, right-size field equipment, and design grain storage structures. These 4 models translate USDA-ARS and ASABE engineering standards into practical on-farm design and performance tools.
Models integrate USDA-ARS NRCS irrigation engineering, ASABE machinery management standards, and USDA-ARS grain storage engineering research. Part of AgrStak's 431-model platform — patent pending.
