Optimizing split fertilizer application

A data processing system comprising:

• one or more processors;
• one or more non-transitory data storage media coupled to the one or more processors and storing sequences of instructions which, when executed using the one or more processors, cause performing:
• receiving, at an electronic device, over a computer network following real time gathered data:
• planting data, fertilizer data, labor data and profit data for an agricultural field;
• based on, at least in part, the planting data, the fertilizer data, the labor cs data, and the profit data, computing, by the electronic device, one or more penalty constraints that specify one or more conditions for determining one or more valid calendar dates, wherein a valid date is a valid calendar date that falls within a pre-planting season and/or within a side-dressing season, and one or more valid fertilizer amounts that are positive numbers selected from a date set determined for fertilizer applications;
• based on, at least in part, the planting data, the fertilizer data, the labor data, the profit data, and the one or more penalty constraints, computing, by the electronic device, an optimized fertilizing schedule that comprises the one or more valid calendar dates on which fertilizing the agricultural field is recommended and the one or more valid fertilizer amounts to be applied to the agricultural field on the one or more valid calendar dates to maximize a yield from the agricultural field;
• causing displaying the fertilizing schedule on a display device;
• wherein instantaneously to the receiving of the real time data gathered in real time, the real time gathered data is used to compute the one or more penalty constraints, to compute the optimized fertilizing schedule in real time, and to display the optimized fertilizing schedule computed in real time.
