REMUNDA SERIES

The Remunda series consists of very deep, well drained soils that formed in alluvium from mixed sedimentary and igneous rocks. These soils are typically on strongly sloping alluvial fans and valley slopes. They have slow permeability. Their slopes range from 1 to 12 percent. Mean annual precipitation is about 15, and average annual temperature is about 45 degrees F.

TAXONOMIC CLASS: Fine, mixed, superactive, mesic Aridic Argiustolls

TYPICAL PEDON: Remunda silty clay loam - range (All colors are for moist soil unless otherwise stated.)

A--0 to 14 inches, brown (10YR 4/3) silty clay loam, very dark brown (10YR 2/2) moist; weak fine subangular blocky structure; hard, friable, sticky and plastic; common fine roots; common fine interstitial pores; neutral; abrupt smooth boundary. ( 5 to 16 inches thick)

BA--14 to 19 inches, brown, (7.5YR 4/2) clay loam, very dark grayish brown (10YR 3/2) moist; moderate medium subangular blocky structure; hard, firm, sticky, and plastic; common fine and medium roots; common fine interstitial pores; neutral; clear smooth boundary, (3 to 8 inches thick)

Bt--19 to 38 inches; reddish brown (5YR 5/4) clay, dark reddish brown (5YR 3/4) moist; moderate coarse prismatic parting to strong coarse angular and subangular blocky structure; hard, firm very sticky and very plastic; few fine roots; few medium tubular and common fine interstitial pores; many thin clay films on surfaces of peds and in pores; neutral; gradual smooth boundary. (10 to 19 inches thick)

Btk--38 to 48 inches; reddish brown (5YR 5/4) clay loam, dark reddish brown (5YR 3/4) moist; moderate coarse subangular blocky structure; hard, firm, sticky and plastic; few fine roots; few medium and fine interstitial pores; few thin clay films on surfaces of peds and pores; matrix is noneffervescent; few, fine, faint, soft masses of calcium carbonate ; mildly alkaline; clear wavy boundary. (6 to 18 inches thick)

Bk--48 to 62 inches; reddish brown (5YR 4/4) clay loam reddish brown (5YR 4/4) moist; weak medium and coarse subangular blocky structure; hard, friable, sticky and plastic; few fine and medium interstitial pores; strongly effervescent; common medium soft masses of calcium carbonate; mildly alkaline.

TYPE LOCATION: Otero County, New Mexico; about 200 yards northwest of lower Indian well and on the east side of the road in a headcut west of the arroyo in the SE 1/4 of SW 1/4 of Sec. 15, T. 14 S., R. 16 E. 105 degrees, 21 minutes, 35 seconds longitude; 34 degrees, 38 minutes, 39 seconds latitude.

RANGE IN CHARACTERISTICS:

Soil moisture: The SMCS is usually moist, in all parts, for less than 90 cumulative days from April through October. It is usually dry, in some part, for more than 120 cumulative days during the same period. The period of maximum precipitation is July through October. The soil is driest during June and October. Aridic ustic moisture regime.

Thickness of mollic: 10 to 20 inches thick.

Reaction: neutral to moderately alkaline.

Depth to calcium carbonate: 30 to 48 inches.

Depth to bedrock: greater than 60 inches.

Soil temperature: 52 to 59 degrees F.

A horizon - Hue: 7.5YR or 10YR. Value: 3 or 5 dry, 2 or 3 moist. Chroma of 2 or 3. Textures: loam, silty clay loam or clay loam.

Bt and Btk horizon - Hue: 5YR through 10YR. Value: 3 through 6 dry, 2 through 5 moist. Chroma:3 through 5. Texture: clay loam or clay containing 35 to 50 percent clay.

Bk horizon - Hue 5YR through 10YR. Value of 4 through 6 dry, 3 through 5 moist. Chroma of 3 through 5. Textures: clay loam or loam with 25 to 40 percent clay. Some pedons contain gypsum below 40 inches.

COMPETING SERIES: These are the Abrazo (NM), Cantina (NM), Carnero (NM), Celososprings (NM), Charette (NM), Concho (NM), Cueva (NM), Partri (AZ), Quivera (NM), and Philmont (NM) series. Abrazo, Carnero, and Cueva soils have bedrock at a depth of 20 to 40 inches. Cantina soils contain more than 30 percent sand in the Bt horizon. Celososprings soils have more than 15 percent rock fragments in the Bt horizon. Charette soils have basalt rock fragments in the control section. Concho soils are calcareous within 24 inches of the surface. Partri have a calcic horizon below the argillic horizon. Quivera soils have 15 to 35 percent rock fragments in the control section. Philmont soils have pedogenic calcium carbonate at a depth of 16 to 30 inches.

GEOGRAPHIC SETTING: Remunda soils have convex slopes of 1 to 12 percent. These soils are on nearly level to strongly sloping alluvial fans and valley slopes at elevation of 5,600 toe 7,400 feet. Parent material are derived mostly from mixed sedimentary and igneous rock. These soils occur in a semiarid continental climate. The mean annual precipitation is about 12 to 16 inches with a summer maximum. The average annual temperature is about 50 to 57 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Gabadon, Rinconada, Ruidoso and Shanta soils. The Gabadon, Rinconada, Ruidoso and Shanta soils have mollic epipedons thicker than 20 inches.

DRAINAGE AND PERMEABILITY: Well drained; slow permeability; slow or medium runoff.

USE AND VEGETATION: Native range, cropland and water shed. Principal native vegetation is blue grama sideoats grama, ring muhly, cholla, and yucca with widely spaced pinyon juniper trees.

DISTRIBUTION AND EXTENT: Valleys in the foot hills and the low mountains of south central New Mexico. The soils are of moderate extent. MLRA 70.
