Band Application Exercise
Scenario: A farmer wants to use band application to apply fertilizer to their cornfield. They have a 10-acre field and want to apply fertilizer in 6-inch wide bands along each row of corn. The fertilizer is packaged in 50-pound bags, and each bag covers 1000 square feet.
Task: Calculate how many bags of fertilizer the farmer will need.
Hints:
- Convert acres to square feet (1 acre = 43,560 sq ft)
- Calculate the area covered by each band per row length
- Determine the total number of bands needed
- Estimate the total area covered by all bands
- Calculate the total bags needed
**
Exercise Correction
Here's how to calculate the fertilizer bags needed:
- Calculate total square footage: 10 acres * 43,560 sq ft/acre = 435,600 sq ft
- Calculate the area covered by each band: 6 inches = 0.5 ft. Assume each row is 100 ft long (adjust based on actual row length). Area of one band = 0.5 ft * 100 ft = 50 sq ft
- Calculate the total number of bands: Total area / area per band = 435,600 sq ft / 50 sq ft/band = 8,712 bands
- Estimate total area covered by all bands: We are assuming a 6-inch band, so the total area covered is roughly the same as the total area of the field, 435,600 sq ft.
- Calculate the total bags needed: Total area / area covered per bag = 435,600 sq ft / 1000 sq ft/bag = 435.6 bags. Round up to 436 bags.
Therefore, the farmer will need approximately 436 bags of fertilizer.
