Efficient Water Management Soil Reservoir as Cup of Water

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?
