Build Your Nitrogen Trust

Variable-rate application acknowledges risk to boost yields

To build a successful variable-rate nitrogen program, it’s essential to have a working knowledge of the nitrogen cycle, nitrogen-supplying power of your soil types and nitrate measurement tools.

"Zone management is very complimentary to variable-rate nitrogen because it factors in the plant’s demand for nitrogen, the soil’s supplying power and the risk of loss. It’s easy to visually identify areas of yellow corn in a field and see the need for more applied nitrogen, but it takes more time and effort when using zone management to assess risk of nitrogen loss and implement variable-rate nitrogen," says Farm Journal Field Agronomist Ken Ferrie.
