1> pull out the Qsoil sensor , clean up the dirt, and fasten the connection between the sensor and transmitter, the readings are 22.61... fixed the problem!! (3:57-4:07pm)
2> clean up the radiometers (4:09-4:15pm)
3> take soil samples (4:07-4:15pm), marked as 1-0cm and 1-3cm (3-6cm sample may not be perfect,since a piece of brick was in the sample tube)
4> shoot the boom , measuring 80 from back so that it should be 80+180=260 (4:25pm)
