Explanation:
Detailed explanation-1: -To illustrate the point, if you purchase a 10-pound bag of fertilizer labeled as 10-20-20, it means the fertilizer contains 10% nitrogen, 20% phosphorus, and 20% potassium.
Detailed explanation-2: -When using percentages in calculations, convert the number to its decimal form (for example, 26% = 0.26; 5% = 0.05). (1.0 lb nitrogen per 1000 sq ft) รท 0.26 = 3.8 lb of a 26-5-10 fertilizer is needed to supply 1.0 lb nitrogen per 1000 sq ft.
