Project Description
Proposal for 4R N Management Science Consensus to Modify Nitrous Oxide Estimation in the Field to Market Fieldprint Calulator
- 1. Context
- The Fertilizer Institute (TFI), the Canadian Fertilizer Institute (CFI) and the International Plant Nutrition Institute (IPNI) are seeking to implement a roadmap for integrating a 4R Sustainability Field Guide and Calculator for reducing carbon intensity of cropping systems in the U.S. over the next 8 to 9 months. The Field Guide and calculator will demonstrate the feasibility of incorporating a module based on the 4Rs into the Field to Market Fieldprint Calculator, for measuring, monitoring and reporting on a reduced carbon intensity metric that has a high likelihood of adoption by growers in the US.
- To coordinate, align and gain consensus on the best available science for improving nitrogen (N) use per unit of crop production and integrating the results into a Sustainability 4R Guide and greenhouse gas (GHG) reduction module for the Field to Market Sustainability Alliance (FtM) Fieldprint Calculator.
- a. A sustainability guide based on 4R N management; and
b. An excel based nitrous oxide emission reduction calculator by region, for baseline emissions, for the crops in the Fieldprint Calculator (wheat, corn and soybean only for the scope of this first stage).
In order to complete the above deliverables, the project team will need to:
a. Develop two reduction modifiers – one for states east of the Mississippi River and one for states west of the Mississippi River (irrigated and non-irrigated corn, soybean and wheat);
b. Develop emission factors or emission equations to estimate baseline emissions by sub-Major Land resource regions in the two areas;
c. Develop the integrated set of BMPs for each performance level (three levels are anticipated) of 4R N Stewardship Implementation Plans.
