The North Carolina Grain Growers Association recently developed a simple calculator/slide rule that will make that conversion for the grower. “It’s a neat little tool that is easy to use to convert seed per acre to pounds of seed per acre,” Weisz says.

On side one of the tool a grower can convert seed per acre to pounds per acre.

On the other side of the calculator they can factor in where in North Carolina they are located, what is the ideal planting date and using that data to calculate the optimum pounds of seed per acre, he adds.

For even more precise planting, the tool will also convert pounds of seed per acre to seed per drill row foot of row.

Weisz cautions growers to not depend on the seeding rate on the table on your grain drill because it is almost always wrong, and is often way off.

“We often do tests on grower farms and in the past have used their planting equipment.

“In one test we were trying to put out 100 pounds of seed per acre and used the information on the planter. In reality we were putting out 190 pounds per acre,” Weisz recalls.

“If you look at the fine print on the manual that comes with some of the grain drills, you will find that the manufacturing company bases the recommendations on a computer model. “They know the charts on the planters are just a rough estimate,” he adds.

Using the planting tool provided by the North Carolina Grain Growers Association, a grower can get the seeding rate right without spending a lot of time converting seeding rates from seed per acre to pound per acre to seed per foot of row.

Getting the seeding rate right, and getting it right based on planting date can both save and make a grower a lot of money.
