Impact and Management of Phosphorus across Various Tillage Practices; A Nutrient Application Field Day

Phosphorus fertilizer is essential to Ohio crop production when applied at correct rates, timing and placement. But, if nutrient applications are not managed, farm field phosphorus can be lost into water resources and promote Harmful Algal Blooms (HAB). Major water quality problems have occurred in Lake Erie, Grand Lake St. Marys and other Ohio water resources in recent years. Within these aquatic ecosystems, harmful organisms - Harmful Algae Blooms (HAB) - have been prevalent in recent years.

To protect Ohio water resources, phosphorus fertilizer must be put in the right place. “Right place likely holds the greatest opportunity for improvement (in water quality as it related to farm field P loss),” The Right Place to Put Phosphorus ; Dr. Tom Bruulsema, Northeast Director of IPNI.

Thus to examine the impact of tillage on phosphorus loss and other crop production factors that influence crop yields, the following field day to be held July 18, 2013 from 8:30 AM, to 2:30 PM in Wood County – a quarter mile west of the intersection of I-75 and Hwy 582 - about 6 miles north of Bowling Green.

8:30 Registration

9:00 Welcome

9:30 Phosphorus (P) Basics

10:10 Cropping System Rotation #1

11:10 Cropping System Rotation #2

Noon Lunch – Compliments of Northern Ohio John Deere Dealers: Findlay Implement, Shearer Equipment and Kenn-Field Group

12:45 Cropping System Rotation #3

1:45 Phosphorus State of the Union

 

The three cropping systems that will be utilized in a rotation are:

  • Phosphorus movement in Full width till systems and related equipment solutions
  • Phosphorus movement in No-till systems and related equipment solutions
  • Phosphorus movement in Strip-till systems and related equipment solutions

The discussion content will focus on the potential mechanisms of phosphorus movement within a tillage system. For example: In a full width tillage system (including conventional tillage and conservation tillage systems) there will be a field demonstration of the ability of various tillage tools to effectively incorporate phosphorus in to the soil profile. Topics covered with the specific tillage demonstration will include particulate P movement via erosion associated with that tillage system, relationship of P soil test levels to P loss, phosphorus solubility within the tillage system, and impacts of tillage on phosphorus stratification, relationship of P stratification to soil test P and soluble P loss.

The field day will be held in Wood County, Ohio – a quarter mile west of the intersection of I-75 and Hwy 582 which is about 6 miles north of Bowling Green. The program is free but an email RSVP is required to nopat@live.com . Please include your name and a phone number where you can be reached in the email. Four and a half hours of CCA credits have been applied for including 1 hour of soil and water and 3.5 hours in nutrient management.
