Are there any other dairy farmers here?
How do you tech on your farm?
I have started to us the LIC MINDA calving and animal lookup apps on my phone and the Web based MINDA Land and Feed.
For recording pasture walks I have a Sail forms pro database on my phone which I enter paddocks covers in and keep other information about paddocks in as well.
We also use CBs to communicate(pretty low tech, but handy).
Use this http://odp.es.govt.nz/apps/fde/guidelines/index.aspx page to check when its ok to spread effluent.
Use my laptop for making bits of documentation and maps.
