Farm Source Dairy Diary is an Android application developed by Fonterra. It is a free business and productivity app that helps farmers to manage their farms efficiently. The app allows farmers to record animal treatments, feed, fertiliser and effluent applications, agrichemical spraying, grazing, and monthly hygiene checks with ease.

One of the great features of the app is that it calculates withholding dates, when to give doses, and RTV dates automatically, which saves farmers time and effort. The app also auto-populates withholdings from the last time you used the drug. This feature helps farmers to analyze treatment records with the team, the vet, or Farm Dairy Assessor.

Another advantage of using Dairy Diary is that it works offline, so farmers can use it around the farm even when there is no mobile coverage. The app also offers seamless synchronization, which ensures that the data is always up to date. Overall, Farm Source Dairy Diary is an excellent tool for farmers who want to manage their farms efficiently.
