Essential Agriculture Variables

Why This Matters

Think of Essential Agriculture Variables (EAVs) as the key building blocks that tell us about what is happening now in agriculture and what we can expect in the near future.  We built EAVs as the science foundation of NASA Acres because:

  • By improving the methods to measure EAVs, we can understand what is happening in agriculture, 

  • With better methods, we can combine these EAVs to increase our knowledge about the interplay between between these variables, and,

  • With increased knowledge about what is happening where and why, we can build these insights into tools that empower decisions in near-real-time.

Essential Agriculture Variables

  • Within-Season Yield Forecasting 

  • Historical Yield Estimation 

  • Cropland and Crop Type Mapping

  • Crop and Crop Type Area Estimation 

  • Crop Planting and Harvest Dates

  • Field Boundaries and Sizes 

  • Cover Crop Utilization and Performance 

  • Crop Residue and Tillage Mapping

  • Canopy Nitrogen Content

  • Rangeland Productivity 

  • Rangeland Forage Quality

  • Evapotranspiration

  • Soil Moisture

  • Soil Organic Carbon and Other Metrics of Soil Health 

  • Pest & Disease Early Detection and Warning

Plus, the EAVs offer a conversational platform for innovation. The EAV framework is a valuable tool for describing what is possible to ask and answer using satellites when conversing with farmers, ranchers, researchers, policymakers, and others interested in agriculture.
