Phosphorus fertilizer is essential to Ohio crop production when applied at correct rates, timing and placement, Prochaska said. But, if nutrient applications are not managed, farm field phosphorus can be lost into water resources and promote hazardous algal blooms.
The cropping systems that will be demonstrated include:
•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 demonstrations will cover the ability of various tillage tools to effectively incorporate phosphorus into the soil profile, which would reduce the possibility of it getting washed away into the area's watershed and increase the likelihood it will stay on farmland to fertilize the crop.
Topics covered with each tillage demonstration will include:
•Particulate phosphorus movement via erosion associated with that tillage system.
•The relationship of phosphorus soil test levels to phosphorus loss.
•The impacts of tillage on phosphorus stratification, relationship of phosphorus stratification to soil test phosphorus and soluble phosphorus loss.
The event is from 8:30 a.m. to 2:30 p.m. in a harvested wheat field a quarter mile west of the intersection of Interstate 75 and Highway 582 in Wood County near Bowling Green. The program, which includes lunch, is free but pre-registration by July 15 is required. To register, send an email with your name, phone number and address to email@example.com.
Four and a half hours of certified crop adviser credits have been applied for, Prochaska said, including 1 hour of soil and water and 3.5 hours in nutrient management.
