ABSTRACT
This chapter analyzes the procedures for supporting decision making in precision agriculture management and for prescription generation. The prescription map is generated to provide guidance for decision making using intelligent precision agriculture equipment, which thus optimized the inputs of fertilizers, water, and pesticides from the economic and ecological perspectives. The generation of a prescription map includes several steps: determining the size of units of the prescription map, converting the format, and developing the coordinate system. The size of the units of a prescription map can be determined by the operation width of the agricultural machine. The automatic soil collection experiment was carried out on June 2007 at Xiaotangshan National Experiment Station for Precision Agriculture. The K-means and spatial contiguous-clustering algorithms were employed to extract the partitions based on the difference in growth status of wheat during periods with higher demand for fertilizer and water.
