Another new module from our team - Equation-based analytics. 

You can use predefined formulas (mostly from US universities, and research organizations) or create your formulas (not shared with anybody else by us). 

A variable in the formula could be mapped to imagery, yield, as-applied, as-planted, soil, LIDAR or GPS topography datasets. 

Several use-cases: 

• NPK use efficiency calculation
• NPK uptake calculation
• Nutrients recommendations based on soil & target yield
• Lime recommendations based on pH data (soil sampling or scanners like SoilOptix)
• ROI calculation in each sqm
• Imagery change detection (subtract vegetation between images)
• Rx vs as-applied analysis
• Potassium Recommendations based on Two Yield Targets (Productivity Zones)

Drop me a message if you're interested to test it (free test, affordable subscription later).
