Reconcile crop yield with user-sourced N, P2O5 and K2O harvested-removal coefficients and a documented nitrogen-removal amount.
Choose your path
Reconcile user-sourced harvested crop-removal coefficients and yield with a documented nitrogen-removal record without calculating uptake, fertilizer need or an application rate.
Reproduce N, P2O5 and K2O removal from the exact coefficient source used in the plan.
Enter harvested yield, three sourced coefficients and the documented nitrogen-removal amount.
Sees each removal total and the signed N comparison.
Keep crop, product unit, moisture basis, part harvested and coefficient year/source explicit.
Confirm those records before entering them and retain residual, manure, irrigation and soil-test credits externally.
Does not confuse removal with whole-plant uptake or crop need.
Avoid converting harvested removal directly into a fertilizer recommendation.
Use the output only inside a complete site-specific budget and current state/local guidance with 4R decisions.
Does not set source, rate, timing or placement from this tool alone.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Reproduce one source-owned analyte stock-dose record from explicit mg/L concentrations and final volume, then compare completed and independent doses.
Enter harvested yield and N, P2O5 and K2O removal coefficients that match the crop, harvested product, yield unit, moisture basis, geography and source used in the nutrient plan.
Each reported removal is yield multiplied by its entered coefficient. The signed primary result compares calculated N removal with the entered documented N-removal record.
Harvested removal is not whole-plant uptake, crop need, fertilizer need or an application rate. A site-specific plan also accounts for testing, credits, losses, risk, realistic yield and source, rate, timing and placement.
Updated: August 2026
Reproduce N, P2O5 and K2O removal totals using the exact coefficient source attached to the crop and product record.
Carry documented harvested removal into a broader budget that separately records soil tests, manure, irrigation water, residuals and other credits.
Use current state or local implementation guidance and a qualified planner; this arithmetic does not establish a compliant nutrient-management plan.
Document crop, harvested part, yield unit, moisture basis, coefficient source and publication year; do not mix unlike bushel, ton or concentration records.
Complete the site-specific nutrient budget and 4R decisions using current tests, credits, risk assessment, local requirements and professional guidance.
This tool reconciles harvested nutrient-removal arithmetic from user-entered source records. It intentionally does not estimate biological uptake, fertilizer requirement, nutrient availability, loss or application rate.
