10. Consider the following scenario. A PSU is bordered on the north and east by county roads. One half is cropland and the other half is permanent pasture. The cropland and non-cropland polygons are the same in 1997 and 1998. In 1998 a filter strip was installed along an intermittent stream in the permanent pasture (non-cropland). The new filter strip extends from within the PSU to a point 200ft outside the PSU boundary (there is not a road along that boundary). Which portion of the filter strip practice is measured for purposes of the 1998 Special Study? (check one) q A. The entire length and area of the 1998 filter strip q B. The entire length and area of the filter strip in the PSU in the cropland polygon ü C. The entire length and area of the filter strip in the PSU in the non-cropland polygon 11. To inventory water areas, order the following steps in their proper sequence beginning with the number 1. 3_ A. Delineate and measure all permanent water areas 2_ B. Identify areas of small and large urban and built-up in the PSU 1_ C. Determine locations of PSU and point samples 4_ D. Classify water areas 12. When the total aggregate area of pastureland, rangeland and conservation reserve program (CRP) acreage is required to describe a buffer strip initiative practice, CRP is? (check one) q A. Derived by delineating total area of pastureland and rangeland and subtracting from the total area of the polygon ü B. Obtained from field office records/locations q C. Known from historic NRI observations with in the PSU 13. A PSU of 160 acres has a north and east boundary along centerlines of paved roads that have 30ft rights of way (grassed). A fence separates the road rights of way from a field, and that field extends beyond the south and west boundaries of the PSU. A 40ft wide grass strip exists in the field between the fence and corn; the grass strip was seeded in 1997 and is visible on 1997 photography. Corn extends beyond the PSUs south and west boundaries. Answer the following questions about the PSU. a. Classify each of the following areas of the PSU in 1997 as cropland (C) or noncropland (N). C_ A. Area of corn in the PSU C_ B. 40ft wide grass strip between fence and corn N_ C. 30ft wide grassed road right of way between paved road and fence N_ D. Portion of the paved road in the PSU
