  1. Hi Jim. I’ve got a question for you that relates to sub-soil water penetration levels. If a soil, on a flat field is completely dry, how many inches of rain have to occur for water to get down to the level where it will not trans-evaporate out? I recognize that this will depend upon soil type, temperature and the speed of the rain, but are you aware of any studies that provide this information or give some examples? As someone that has farmland, I wonder sometimes if the soil is getting wet 7-8 feet down? Not sure how long it takes to get down there and how much water is needed. Thanks.

  2. That’s a hard question to answer because it does depend on the soil type, drainage, time of year, and how the rain falls. A very rough estimate is that if the soil was bone dry, then it takes about 2 to 3 inches of rain to recharge each foot of soil.And you have to start at the top and work your way down. First the topsoil recovers then the water starts to work downward from there. Those deeper layers are slow to dry out and also slow to catch back up.
