Start Your Corn’s Engine With Popup

For a slight premium versus broadcast fertilizers, popup fertilizers can increase your no-till corn yields to the point of tripling your investment.

Are you ready to give your no-till corn crop a great start?

For years, producers have used starter fertilizers to ensure a good start for their corn. This is a proven management practice that can increase yields and profits.

In fact, starter fertilizers may even boost your seedling’s growth to the point that your conventional-tilling neighbor will wonder why your crop growth is keeping up with or even passing his corn.

Crop nutrients in cold soils are just not as available to small corn plants as in warmer soils. Thus, providing quick access to nutrients will let your seedlings take off and maximize their yield potential.

Starter placed 2 inches deep and 2 inches away from the seed has been a common practice. But with today’s larger planters, many no-tillers have switched to popup fertilizers to minimize machinery investment and improve labor efficiency.

Studies at the University of Minnesota have shown popup works well. However, caution must be taken to avoid seed burn from too much salt, which can reduce germination and stands. With popup fertilizer, a little bit is good, but too much can be bad.

Researchers in Minnesota and Wisconsin generally recommend that you use popup fertilizers with a salt index of 20 or less and limit rates to 7 to 8 gallons per acre in 30-inch rows. This will minimize the chances of the fertilizer impacting germination, yet allow young plants quick access to nutrients for improved growth and yields.
