Question

A TDR probe of a length of 60 cm was installed vertically into a soil profile before 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)? Thanks in advance :)
