The Nutrient Manager for Rice software is an interactive computer-based decision tool designed to help extension workers and farmers quickly formulate fertilizer guidelines tailored to specific rice fields or rice-growing conditions. It is based on the principle of site-specific nutrient management (SSNM) for rice. It was released in 2008 and disseminated on CD throughout the Philippines with the concomitant training on its use. Since 2009, we have used information technology to facilitate access of more farmers and extension workers to guidelines provided by the Nutrient Manager for Rice. A web application was released: www.irri.org/nmrice. Recently, it was updated as a mobile phone-compatible application, but only HTML-Capable phones can access the software. Such applications depend on availability and speed of internet connection, require special phone features, and entail cost on the part of the users. An interactive voice response (IVR) application is also under development and evaluation. The user calls a toll-free number to access the software. Once connected, a voice prompt instructs the caller to select statements describing his/her field conditions by pressing the number on the phone; after all statements are answered, the field-specific fertilizer guidelines are sent as text messages. Extension workers and farmers now have field-specific nutrient management for rice at their fingertips.
