The Potato Calculator: a tool for scheduling nitrogen fertilizer applications


, : The Potato Calculator: a tool for scheduling nitrogen fertilizer applications. Agronomy New Zealand 36: 49-53

A simulation model based decision support system, the Potato Calculator (PC), was tested in farmer crops over three years. The PC provides an accounting system for growers to keep track of the N in their system, and apply additional N fertilizer according to crop need. Two aspects of the PC were tested: (1) the yield and environmental consequences of the PC guided fertilizer advice; and (2) the accuracy with which the PC could predict yield and environmental impacts.
