Harvest Leader Manual

  Advanced problems 2

This is the second of several advanced harvest planning scenarios that combine much of the information found in the scouting and harvest sections of this manual. The online manual's format is not ideal for these but they can give leaders good practice at planning, especially the kinds of calculations that can be necessary. Some scenarios or questions will run over into the next section. You may need to refer to the Database:formulas section or the Reports Generator page to find some of the numbers that you need.

Harvest Planning Scenario - blueberries A blueberry site shown in the aerial photo must be picked in one day because the owners are going on vacation. The bushes are planted at 600 plants per acre. You pick an average bush and get 3 pounds. Parking is restricted to the yellow square 180 feet on each side.



Follow the questions below and in the next section about this harvest planning scenario.




How many pounds are available to harvest?
1800 lbs
4000 lbs
2700 lbs
Question 1 explanation:
The area of the blueberry bushes is about twice the size of the yellow square:

180ft x 180ft x 2 = 64,800 sq ft [from the aerial view]
64,800 sq ft = 1.5 acres [using the website calculator]
1.5 acres = 900 plants [from the given information]
900 plants = 2700 pounds of blueberries [from your test pick of one bush]

How many pickers would it take to pick 2700 pounds of blueberries in two hours?

100-125
135-180
160-200
Question 2 explanation:
Our blueberry pickers average 15-20 pounds each. [from the Reports page]
2700 pounds = 135 to 180 pickers.

How many cars can be parked and how many pickers will they bring?

60 cars, 104 pickers
90 cars, 126 pickers
90 cars, 98 pickers
Question 3 explanation:
180 ft of head-in parking = 18 cars [from the website calculator]
Parking spaces are 20 feet long and must have 25 feet between rows [from the Database: formulas section]
|--20--|--25--|--20--|--20--|--25--|--20--|--20--|--25--|
|------|      |------|------|      |------|------|      |
|------|      |------|------|      |------|------|      |
|------|      |------|------|      |------|------|      |

5 parallel rows = 90 cars
90 cars = 126 pickers [from the website calculator]

How many pounds will 126 pickers donate?

945-1260
568-1000
824-956
Question 4 explanation:
Total pounds will be 1890-2520 [16 times 15-20 pounds each]
Donated pounds will be 945-1260 [half of the total]
