Crop Nutrient Removal Calculator (PlantCalc) for iPhone/iPad/iPod touch

The calculator estimates crop nutrient removal of nitrogen (N), phosphorus (expressed as P2O5), potassium (expressed as K2O), and sulfur (S) for a broad, and continually expanding, list of field crops.

Results are calculated based on user-selected yield goals, and can be displayed in either metric or US/Imperial units. The calculator is uniquely multilingual—providing full access in six languages including English, French, Spanish, Portuguese, Russian, and Chinese (Mandarin).
