You can find Mastery by clicking your Mastery, Achievements, and Collections button.

Mastery measures how quickly you can plant or harvest one plot of land. When you first start Country Life Meadows, it takes 1.0 second to plant or harvest a single plot.
Each star you earn reduces this time by 0.1 seconds. With all stars unlocked, it takes only 0.3 seconds per plot.
Important: Mastery does not affect how long crops take to grow — it only speeds up the planting and harvesting actions themselves.
On a small Farm this difference is minor, but on a large Farm with 700+ plots the time savings add up significantly.
In the Mastery tab you’ll see exactly how much time you save for each plant when planting and harvesting — just hover over the next star to see the info.

Note about the RC option
The number of RC under the stars is not a prize. It’s a button that lets you buy the next star immediately using your RC instead of harvesting the required number of plots.
No Achievements Button
You can add the Achievements button to your HUD buttons from Settings → Page 5.
