I measured the amount of water the soil absorbed versus the time to determine infiltration rate. The soil became saturated at about 50% as measured by the EC-5 at 30.5 cm and 66cm. The initial soil moisture content was about 7% so water I applied is leaching into the surrounding soil. After a day the log of the moisture content appears to plot linearly with time suggesting an exponential decay. What literature can you suggest to analyze this type of data? What I've found doesn't seem to take advantage of the wealth of soil moisture readings your instruments provide.

Hi Bill,

That is a really good questions and I apologize about the delayed response. One of our research scientist recommended the book "Soil Physics with BASIC" pgs. 90-92. He also recomended Walt Gardner's Soil Physics book. If you are interested in a PDF copy of the pages that were recommended from the Soil Physics with BASIC book, send us and email at support@decagon.com and we will forward you a copy of those pages. I hope this helps answer you questions.
