The document provides details about an agronomy internship at Deseret Farms of California during the summer of 2016. It includes background information about the intern, Cody Deitz, and outlines several projects he worked on, including new orchard development, GPS work, tree evaluations, well testing, and sand testing. It discusses specific tasks like creating tree arrays, evaluating tree growth, and measuring tree trunk diameters to compare trees that were replanted after fumigation to those that were not.

8. Tree Evaluation-Wilson 547
Would the trees that were
replanted after spot fumigation
be larger than those that were
not?
17x56 test area in North West
Corner on east side of field
547.
Measured the north side of
each tree trunk
approximately 4 to 6 inches
from the ground.
