This document discusses developing mobile Android clients for an information and communication infrastructure in agriculture. It proposes using semantic technologies and connectors to allow sharing of data between farmers, machines, retailers and consultants. This would include field information, orders, harvest yields and more. The system would use messaging and data synchronization between mobile devices and databases to allow offline access. Challenges include implementing this with technologies like Couchbase Mobile and GeoCouch to create mobile geoform applications.
