ASSIGNMENT 6

 

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

 In mapunit table NM963 oil describes in terms of hydrologic soil group (percent A, B, C, or D) with 0% A, 2%B, 12%C, and 86%D.

 The components table, the soil has the properties of

8.Do these soil properties make sense considering where this soil is located?

The soil properties in Pecos Basin are mostly made of hydrologic soil group D, which is clayey, poorly drained soils. And from the above chat we can be sure that the predominant soil is fine sandy  loam.This soil has high runoff potential soils so it has very slow infiltration rates.

From the figure below, we can see that the Pecos Basin is located along the streams, so the river would be the cause of this kind of soil, which make sense.

Figure: NM963 location

 

 

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?
