Efficient Water Management When and For How Long do I Irrigate?
  • Need to know 4 things:
      • How much water does my cup (soil reservoir) hold?
      • How fast am I losing that water?
      • How much water can be removed from my cup (soil reservoir) before I need to refill it?
      • How long will it take my sprinklers to refill it?
