Project Type: Reimbursable Cooperative Agreement
Start Date: Oct 1, 2016

1. Adapt and evaluate a process-based model that estimates the fate of nitrogen (N) and phosphorus (P) for confined beef cattle housing/manure management methods, including bedded manure pack and deep pit manure storage in mono-slope or hoop-style buildings. 2. Adapt and evaluate a process-based model that estimates the N and P availability and losses from land applied solid beef cattle manure (with and without bedding). 3. Evaluate housing, manure management and crop production scenarios for N and P fate and farm profitability under variable climatic conditions.
The approach utilizes a two year plot-scale land application study replicated at three sites in the Northern Great Plains region and a two-year-farm-scale barn manure storage emission study to obtain data on N and P losses as affected by manure management. Collected and existing data will be used to adapt and evaluate an existing process-based model, the Integrated Farm System Model (IFSM). The national-scope process-based model will then be used to investigate the effects of variable climatic conditions on these and other scenarios of integrated beef cattle and crop production. This project integrates multiple commodities. While the scope for data collection is the Northern Great Plains region, the modeling aspects of the project are transferable to other commodities and to a national scale.
