Planter and Drill Overview
On-Track Submission:
Prior to midnight, day of Lab #11
Educational Objectives:
1.
To become familiar with row crop and seeding equipment;
2.

Problems from Dr. Bob:
5.
When checking the calibration of your 20
”
Row Crop Planter, you measure 5
seeds per foot of linear run.
What is the seeding rate in seeds per acre?
6.
When checking the calibration of your 30
”
Row Crop Planter, you measure 8
seeds per foot of linear run.
What is the seeding rate in seeds per acre?
7.
The desired harvest population of plants is 128,000 per acre.
This variety of seed
has a historical germination rate of 98.5%.
The plant survival rate is 94.5%.
What should be the Planter Seeding Population Target?
