This proposal is intended to monitor the nitrogen requirement and overall fertilizer cost contrasting fall applied hog manure with side-dress nitrogen, strip till with side-dress nitrogen, and conventional tillage with side-dress nitrogen. To do this several nitrogen modeling tools will be utilized (Adapt-N, Encirca, and Climate FieldView).
The test will provide results regarding the accuracy and usability of several commercially available nitrogen modeling tools. Deliverables will include cost analysis of each method of nitrogen use Cost/Pound of Nitrogen, Cost/Acre, and Cost/Bushel. Additionally, cost and benefit analysis for each of the nitrogen management tools will be included. Items of consideration include price, usability, accuracy of output, as well as set-up and use hours required t make software functional.
