This interactive web page is designed to calculate how much seed you will need for a particular field, a particular variety, part of a field for a particular variety, or for your entire crop. You have two calculator options, depending on your choice of input.
Calculator “A” requires you to input your row spacing, the seed spacing you will plant, and the number of acres for this particular combination of variety and field size.
Calculator “B” requires you to input your row spacing, your target established plant population, your estimate of percent emergence in this particular field, and the number of acres for this particular combination of variety and field.
You can enter new information and perform the calculation again for as many combinations as you want. You can also print out the results with input information for each calculation.
