Look at Figure 3-4: Sample Site Data Worksheet above that has been partially
completed for this property. Using this worksheet, complete the items below.
1. Section 4 of the Worksheet indicates that the climate is “Warm Dry.” What is
the actual worst-case daily PET for this type of climate, according to Table 3-
4? Fill in this figure on the sample Site Data Worksheet.
2. What is the application efficiency for a low-volume system in a Warm Dry
climate according to Table 3-4? Fill in this figure on the sample Site Data
Worksheet.
3. Hydrozone 7 is completely covered with ground cover. It also includes
shrubs and trees. Enter your best estimate of the hydrozone’s density on the
sample Site Data Worksheet.
4. Hydrozone 9 will be a vegetable garden when it is planted. What density do
you think should be used to plan for this hydrozone? Enter your estimate on
the sample Site Data Worksheet.
Suggested answers for these four items can be found on the last page of this
chapter. Check your answers with this answer key.
