Spatial Averaging Soil Properties using Comppct

Describe the NM963 soil in terms of its properties in the Mapunit and Component Tables:

1.       How many components does it have? 8

2.       What are their names? Regnier, Latom, Rock Outcrop, Los Tanos, Gallen

3.       What percentage of the map unit does each component comprise?

3.1.     Regnier – 27%

3.2.     Latom – 27%

3.3.    Rock Outcrop – 18%

3.4.    Los Tanos – 12%

3.5.    Regnier – 7%

3.6.    Latom – 5%

3.7.    Regnier – 2%

3.8.    Gallen – 2%

4.       What is the predominant surface slope where this soil unit is found? Around 15%

5.       What is the dominant soil texture? Fine sandy loam

6.       What percentage of the soil is in hydrologic soil groups A – 0%, B – 12.5%, C - 12.5%, D – 75%?

7.       Do these soil properties make sense considering where this soil is located? Sure, if meaning located in New Mexico.

1.       How many layers does each component have?

2.       What is the total soil depth (inches) for each layer and the average depth (inches) for the map unit?

3.       What is the total water holding capacity (inches of water) over the full soil depth for each component?

4.       What is the average water holding capacity (inches of water) for soils in this map unit?

Layout showing soil type


 

           

Layout showing land use:

I found Land Use data for Santa Fe and Fort Sumner on the RGIS website, but it did not have LUCODE, rather a GRID CODE and was separated into east and west halves, looks roughly equivalent; successfully merged and then clipped.

 

Unable to ‘intesect’ land use and soil.
