Abstract
Precision agriculture has the potential to enhance farming profitability substantially via site-specific management of fields. One of the promising ways of generating such profitability-enhancing input is to a use recommendation map is on-farm randomized trials. The process of generating an input (say nitrogen) using a recommendation map typically involves the following steps:
1. Design and implement randomized input use trial
2. Collect yield data along with other field characteristics (Slope, Electrical Conductivity, and Organic Matter)
3. Process the data for statistical analysis
4. Conduct regression analysis to estimate production function (how the input affect crop yield)
5. For each of the management units, find the input rate that maximizes profit for that unit
