3. What is the predominant surface slope where this soil unit is found? What is the dominant soil texture?
The predominant surface slope is 36% Regnier with average slope of all three area being 178. Coming in second, Latom comprises 32% of map unit with an average 12.16 surface slope. The dominant soil texture is the FSL at 39 % and CL comes in second at 34%
4. What percentage of the soil is in hydrologic
soil groups A, B, C, D?
A- 0
B- 2
C- 12
D- 86
5. Do these soil properties make sense considering where this soil is located?
Yes, considering that in this
For mapunit NM963, how
many layers does each component have? What is the total soil depth (inches) for
each layer and the average depth (inches) for the map unit? What is the total
water holding capacity (inches of water) over the full soil depth for each
component? What is the average water holding capacity (inches of water) for
soils in this map unit?

The following are the maps that were created. Note comparison maps- they will be useful next I merge or join datum.
This copy of a section of 963shows how the map look
prior (top) to the merged soils data (bottom)
Note the label name… “merge”, this combined the different shape files into one data set.
This exercise was extremely useful in that it exposed me
again to the vast megadata that is
located with ERGIS, USGS and RGIS. A good site that we used for soil
information was the site: //soildatamartexport.sc.egov.usda.gov/export/e_932403/gsmsoil_nm.zip
from the USDA. Also the Natural Resource
Conservation site had a wealth of data.
