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

COMPPCT	SURFTEX
27	CL
27	FSL
18	UWB
12	FSL
7	CL
5	GR-FSL
2	GR-SCL
2	GR-SL

2.How many components does it have?

It has 8 components.

3.What are their names?

SURFTEX	Names
CL	Clay Loam
FSL	Fine sandy loam
UWB	UWB
FSL	Fine sandy loam
CL	Clay Loam
GR-FSL	Gravel fine sandy loam
GR-SCL	Gravel sandy clay loam
GR-SL	Gravel sandy loam

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

SURFTEX	COMPPCT
CL	27
FSL	27
UWB	18
FSL	12
CL	7
GR-FSL	5
GR-SCL	2
GR-SL	2

 5.What is the predominant surface slope where this soil unit is found?

SURFTEX	SLOPEL	SLOPEH
CL	3	15
FSL	1	15
UWB	0	99
FSL	0	5
CL	15	35
GR-FSL	15	40
GR-SCL	30	80
GR-SL	5	35

 6.What is the dominant soil texture?

CL, or FSL both covers 27% and are the dominant soil texture.

7.What percentage of the soil is in hydrologic soil groups A, B, C, D?

A_PCT	B_PCT	C_PCT	D_PCT
0	2	12	86

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?
