Stateler Farms Nutrient Application

The Nutrient Management Standard, or 590 Standard, is used to manage rate, source, placement and timing of plant nutrients and soil amendments while reducing environmental impacts. Conservation planners can use this practice on all fields where plant nutrients (commercial fertilizer and/or manures) are applied.

This practice is used to accomplish one or more of the following purposes:

  • Improve plant health and productivity to reduce excess nutrients in surface and groundwater.
  • Improve air quality.
  • Reduce the risk of potential pathogens from manure, biosolids or compost application from reaching surface and ground water and/or improve or maintain soil organic matter.

In January 2020, the Natural Resources Conservation Service began to revise its Field Office Technical Guide for the Nutrient Management Standard. Part of that process included the formation of a 19-member subcommittee of the NRCS State Technical Committee (590 Task Force), which brought diverse and experienced experts, specific to Ohio, to collaborate on the revision.

“When the 590 Standard was revised nationally, we wanted to get a better handle on how we can identify levels of risk to address the potential for off site movement of nutrients,” said Ohio Farm Bureau’s Senior Director of Policy Development and Environmental Policy Dr. Larry Antosch, who was part of the 590 Task Force. “What we really got into was the distinction between agronomic endpoints and environmental endpoints or risks utilizing the Tri-State Fertilizer Recommendations.”

According to those tri-state recommendations, when soil test phosphorus levels are above 50 parts per million (ppm) Mehlich III, the application of additional fertilizer will not result in a yield increase. When those levels reach 120 ppm or higher, the likelihood of the off-site movement of phosphorus increases. A phosphorus soil test around 50 ppm is referred to as the agronomic threshold, whereas a phosphorus soil test level at or above 150 ppm is referred to as the environmental threshold.

After 14 meetings spanning over six months, the 590 Task Force made some minor changes to the endpoints for the four levels of phosphorus loss risk – low, moderate, high and very high. Those modifications will be used to protect Ohio’s water quality and are practical and realistic for Ohio farmers to implement and adopt.

Labor has always been an issue, mainly because we are a seasonal operation. So that's a challenge finding somebody who only wants to work three months out of a year, sometimes up to six months.

I appreciate the benefit of having a strong voice in my corner. The extras that are included in membership are wonderful, but I'm a member because of the positive impact to my local and state agricultural communities.

Strong communities
I see the value and need to be engaged in the community I live in, to be a part of the decision-making process and to volunteer with organizations that help make our community better.

Farm Bureau involvement has taught me how to grow my professional and leadership experience outside of the workforce and how to do that in a community-centric way.

With not growing up on a farm, I’d say I was a late bloomer to agriculture. I feel so fortunate that I found the agriculture industry. There are so many opportunities for growth.

Knowing that horticulture is under the agriculture umbrella and having Farm Bureau supporting horticulture like it does the rest of ag is very important.

If it wasn't for Farm Bureau, I personally, along with many others, would not have had the opportunity to meet with our representatives face to face in Washington.

So many of the issues that OFBF and its members are advocating for are important to all Ohioans. I look at OFBF as an agricultural watchdog advocating for farmers and rural communities across Ohio.
