Expert farmers in Story of Seasons: Pioneers of Olive Town will want sprinklers for their farm.
Sprinklers go off every morning automatically and water the eight tiles around it. This automates your farming process and saves you time and stamina, allowing you to do other things instead.
To get sprinklers, you’ll have to hit fieldwork level 4, and then craft them. You can increase your fieldwork level by tilling land and watering crops.
Each sprinkler requires five iron ingots and three silver ingots, meaning that early on in the game, you probably won’t have the materials to make tons of sprinklers. You can place a maximum of 100 sprinklers on your farm.
Once you hit fieldwork level 8, you’ll be able to craft enhanced sprinklers, which require 10 iron ingots, five silver ingots, and three gold ingots to craft. These water the 24 squares around them automatically.
Keep in mind that, if you till land and then place a sprinkler down, the land around it won’t automatically be watered. You’ll need to use your watering can that day, as the Sprinkler won’t activate until the following morning.
