Patent ID: 8671006

Claim:
A method of proactively 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; storing the management, weather and soil data as a data structure on at least one non-transitory computer readable storage medium; calculating an emergence date at least partly from the planting date; calculating a plurality of predicted 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 predicted 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 providing a schedule of proactive recommended nitrogen application values, irrigation values and application dates; for future treatment, the schedule calculated at least partly from the predicted nitrogen deficit values and the predicted water deficit values.
