POLYACRYLAMIDE WORKSHEET #2
Calculating Granular
Rates Based on Pounds Per Acre
STEPS:
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.
