This document discusses the need for mobile agricultural advisory services in India. It notes that most of India's rural population depends on agriculture but farmers do not always receive timely scientific advice.

The document also references a survey of existing Android apps for the agriculture sector conducted by Hetal Patel and Dharmendra Patek.
