One Farmer. One Stack.
Planting density, fertilizer N-P-K, GDD tracking, irrigation scheduling, soil test interpretation, yield forecasting, lime requirements, and crop rotation analysis — powered by USDA NASS, ARS, and NRCS research data.
World Agricultural Supply and Demand Estimates — auto-populate price and yield fields into calculators below.
SF1-S.001
Calculate optimal seeding rate in seeds/acre and lbs/acre. Adjusts for germination rate, row spacing, and field conditions using USDA ARS calibrated population targets.
SF1-S.002
Generate nitrogen, phosphorus, and potassium recommendations from soil test results and yield goal. Integrates NRCS soil data with university extension fertilizer guidelines.
SF1-S.003
Track crop development stages using GDD accumulation. Identify current crop stage and days to maturity using USDA ARS calibrated base temperatures and phenological milestones.
SF1-S.004
Calculate crop water requirements and irrigation timing. Based on the USDA ARS AZSCHED / FAO-56 evapotranspiration methodology.
SF1-S.005
Interpret soil test results for pH, organic matter, CEC, phosphorus, and potassium against NRCS critical thresholds. Generates lime and amendment action recommendations by crop.
SF1-S.006
Estimate crop yield potential and compare against USDA NASS county benchmarks. Models soil productivity rating, water regime, and management on expected yield.
SF1-S.007
Calculate agricultural lime application rate to raise soil pH to target. Uses the NRCS SMP buffer pH method and adjusts for lime quality (ENM/ECC).
SF1-S.008
Quantify the agronomic and economic benefits of crop rotation. Models nitrogen credit from legumes, yield response, and disease pressure reduction from USDA ARS long-term rotation research.
