4R Nutrient Stewardship
Description
Run Time: 1:00:20
More than 250 agricultural retailers and stakeholders from the Ohio, Indiana and Michigan agriculture communities attended the launch of the 4R Nutrient Stewardship Certification Program in Perrysburg, Ohio. This voluntary program is geared toward the long-term improvement of Lake Erie's water quality by applying the 4R Principles:
The 4R nutrient stewardship principles are the same globally, but how they are used locally varies depending on field and site specific characteristics such as soil, cropping system, management techniques and climate. The scientific principles of the 4R framework include: Right Source – Ensure a balanced supply of essential nutrients, considering both naturally available sources and the characteristics of specific products, in plant available forms. Right Rate – Assess and make decisions based on soil nutrient supply and plant demand. Right Time – Assess and make decisions based on the dynamics of crop uptake, soil supply, nutrient loss risks, and field operation logistics.
Right Place – Address root-soil dynamics and nutrient movement, and manage spatial variability within the field to meet site-specific crop needs and limit potential losses from the field. The presentation is a panel discussion that took place at Perrysburg Holiday Inn.
