About Atlas Rice Crop Manager

The Atlas Rice Crop Manager provides irrigated and rainfed lowland rice farmers in the Philippines with a rice crop and nutrient management guideline customized to the needs of an individual farmer. The Atlas Rice Crop Manager uses a farmer's answers to questions on their rice farming practices to automatically generate a rice management guideline aimed at increasing the farmer's net income.

The Atlas Rice Crop Manager is designed for use by extension workers, crop advisers, input providers, and providers of services who interview a farmer using a personal computer, smartphone, or tablet. After the interview, the collected information is stored on the computer, smartphone, or tablet until the device is connected to the Internet through a Web browser. Collected information is then transmitted via the Internet to the Atlas Rice Crop Manager 'model', which calculates and transmits a crop management guideline within moments back to the computer, smartphone, or tablet. Each guideline provides an actionable and unique recommendation for the crop, which matches the location-specific cropping practices and needs of a farmer. The guideline is provided to the farmer as a one-page printout.

The Atlas Rice Crop Manager was developed in collaboration with the International Rice Research Institute (IRRI). The crop management recommendations provided by the Atlas Rice Crop Manager match the recommendations provided by Rice Crop Manager, which has been released nationwide in the Philippines through the Department of Agriculture. The fertilizer recommendations provided by the Atlas Rice Crop Manager match the recommended rates of fertilizer N, P2O5, and K2O determined by Rice Crop Manager.
