Anhydrous Ammonia Rate from Target Nitrogen
The anhydrous ammonia product a nitrogen target needs: anhydrous is 82-0-0 (82% N), so product = target N / 0.82, and at about 5.15 lb/gal that is the gallons per acre; a nurse-tank's gallons over that is the acres it covers. A 180 lb N/acre target is about 219.5 lb (42.6 gal) of anhydrous per acre, so a 1,000-gal tank covers about 23.5 acres. Anhydrous is a pressurized, hazardous liquid -- set the applicator with a flow monitor, calibrate against a weigh/flow check, allow for temperature and vapor, and follow the label and safety (PPE, water, closed transfer) requirements. A rate estimate; the applicator calibration, the soil-test N recommendation, and the co-op / label govern. Distinct from the NPK blend (npk-blend), which solves into urea/DAP/potash.
Formula and source
product_lb_per_ac = n_target_lb_per_ac / 0.82; product_gal_per_ac = product_lb_per_ac / 5.15; acres_per_tank = tank_gal / product_gal_per_ac.
Anhydrous ammonia fertilizer grade (82-0-0) and liquid density (~5.15 lb/gal), by name; extension-service and co-op practice. The soil-test N recommendation and the label govern.
