See the formula
Product rate = 45 lb ÷ 15,000 sq ft × 1,000 = 3 lb per 1,000 sq ft
Zone product = zone area ÷ 1,000 × product rate
N = product × 24% · P₂O₅ = product × 0% · K₂O = product × 11%
Calculated from the fertilizer label’s guaranteed analysis. P₂O₅ and K₂O are label values, not elemental P and K.
