System and method for managing and predicting crop performance

A computer readable medium having stored thereon computer executable instructions that when executed on a computing device cause the computing device to perform a method of managing fertiliser and irrigation inputs for a crop, the method comprising:

• obtaining management data for the crop, the management data including a planting date for the crop;
• obtaining weather data representative of the geographic area of the crop;
• obtaining soil description data representative of the geographic area of the crop;
• calculating an emergence date at least partly from the planting date;
• calculating a plurality of nitrogen deficit values at least partly from the emergence date and the soil description data, the nitrogen deficit values associated with respective dates each later than the emergence date;
• calculating a plurality of water deficit values at least partly from the emergence date and the weather data, the water deficit values associated with respective dates each later than the emergence date;
• and
• presenting on a display a schedule of recommended nitrogen application values, irrigation values and application dates, the schedule calculated at least partly from the nitrogen deficit values and the water deficit values.
