Supported Crops

Prescriptions matched to today's crop

Each model is trained for its crop's growth stages and stress patterns. Corn and Soybean prescriptions use different satellite signals and thresholds.

Row crops

What Harva watches

What Harva watches by crop

Crops express stress differently across growth stages. Harva models use species-specific satellite bands and sensor thresholds.

Corn

  • V6 through VT greenness deviation
  • Fungicide timing windows from canopy humidity thresholds
  • Zone-level soil water deficit from tassel through black layer
  • Mid-season nitrogen uptake signals from NDRE readings

Soybean

  • Canopy closure versus field-average benchmark at R1-R3
  • Combined heat and water stress flags pod abortion risk
  • Leaf spectral indices flag potassium and sulfur deficiency
  • Canopy density and humidity indicate white mold pressure probability

Wheat

  • Early NDVI estimates of tiller density guide nitrogen splits
  • Temperature and leaf wetness hours flag stripe and leaf rust pressure
  • Heading uniformity flags mark zones at risk for late frost damage
  • Track grain fill rate from Jointing through soft dough

Cotton

  • Squaring stage canopy cover flags monitor first-fruit set
  • Heat accumulation and water deficit signal boll retention stress
  • Heat units and boll maturity estimates set defoliation timing windows
  • Post-emergence greenness maps show stand establishment variation

Sorghum

  • Canopy height estimates indicate panicle development stage
  • Rolling soil water deficit guides drought avoidance scheduling
  • Grain fill humidity accumulation signals mold and head blight risk
  • Yield potential zone maps use vegetative-index divergence

Sunflower

  • Late-season canopy reflectance estimates head diameter
  • Flowering-period soil moisture profiles indicate Sclerotinia risk
  • Early-season temperature and humidity indicate downy mildew pressure
  • Head color change rate detection flags harvest timing
