A TDR probe of a length of 60 cm was installed vertically into a soil profile befor e seeding wheat in the spring. TDR reading on May 15 (beginning of the season) was L0 = 2.900 m ; L1=5.114 m. On the day of harvesting September 8 (end of the season), the reading was L0 =2.900 m and L1=4.331 m. Assume there is no rainfall, what was the total change in soil water storage in the root zone (60 cm depth)?

Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.
