Genetics, both plant and animal, will probably be amazing.
Meds, vac, ect will also be a big one.
You will start seeing more electronic monitoring also. They say Wi-Fi will be floating in the air every where in the real near future. That will make all the monitoring devices practical. Just think if you start tracking all your cattle and see how far they travel for water, feed, shade, ect. That will be an efficiency game changer.
Solar/ battery powered items will be more prevalent and work better in general. That technology is going to explode very soon.
... and I do think quality of things you purchase will get better. With the enet and things like forums you can see thousands of reviews for a product in seconds. At the end of the day that equals accountability.
Looking back its interesting what has changed the game the last hundred years.

tractors, trucks, trailers
battery and solar panels on water wells, hot wire fences, ect
