You just measure the distance needed for your row spacing and then count the seeds/plants in the measured distance.
Here are the distances for different row spacing:
40 inch row 13 ft. 1 in.
38 inch row 13 ft. 9 in.
36 inch row 14 ft. 6 in.
30 inch row 17 ft. 5 in.
22 inch row 23 ft. 8 in.
20 inch row 26 ft. 2 in.
15 inch row 34 ft. 10 in.
So measure this distance and multiply by 1000 and you have the population. I use this when setting my planter and to check actual stands several time during the growing season. I have found a big difference in some varieties in final stands. It is just a tool to use when picking your seed corn.
