1. Determine the area irrigated by one irrigation set. Use feet for distances
2. Acres served multiplied by 454 grams/lb = total grams needed at 1# /acre. Greater or less than 1 pound per acre (454 g) may be required.
3. Estimate the furrow advance time. Divide the total grams needed by hours of advance to obtain the advance phase rate in grams/hr.
