Why it pays to test your soil nitrogen

With spring planting right around the corner, Iowa Farm Bureau and Iowa State University (ISU) are hosting a webinar, "Why it Pays to Test Your Soil Nitrogen," at 1 p.m. March 27.

The free webinar will discuss new ISU data and tools regarding this season's nitrate trends that can translate into practical, cost-saving tips for this season.

ISU researchers Matt Helmers, Mike Castellano and Richard Roth will share findings from their recent modeling of soil mineralization and the factors contributing to naturally high soil nitrogen levels this winter, along with the latest nitrogen fertility support tools available to farmers to reduce input costs and support yield goals while protecting water quality.

Presenters will break down what's driving this winter's unusual soil N levels and explain how strategic soil nitrate testing can determine how much nitrogen your soil is already providing to help stretch fertility budgets without sacrificing yield goals.

"Since 98% of the nitrogen in Iowa's soil is naturally occurring, the key is understanding how environmental conditions drive its availability. Our new modeling sheds light on that and gives farmers new insight to fine-tune their nitrogen rates so they can balance economic returns with environmental stewardship," said Castellano.
