MONTVERDE SERIES

The Montverde series is a member of the euic, hyperthermic family
of Typic Medifibrists. These soils have formed in herbaceous
organic deposits more than 51 inches thick. Beneath the black
muck surface layer they are mostly dark reddish brown peat. TAXONOMIC CLASS: Euic, hyperthermic Typic Medifibrists

---

TYPICAL PEDON: Montverde muck--cultivated.
(Colors are for moist soil unless otherwise
stated.)
Oap--0 to 11 inches; black (5YR 2/1) unrubbed and rubbed,
muck; less than 5 percent fiber rubbed; moderate medium granular structure; friable; sodium pyrophosphate extract is pale brown
(10YR 6/3) estimated 5 percent mineral material; medium acid;
clear wavy boundary. (0 to 14 inches thick)
Oi1--11 to 20 inches; dark reddish brown (5YR 2/2), black
(5YR 2/1) rubbed; undecomposed organic material (peat); 80 percent fiber, 70 percent fiber, rubbed; massive; sodium pyrophosphate extract is white (10YR 8/2); estimated 5 percent mineral material; about 90 percent herbaceous; slightly acid; gradual wavy boundary. (8 to 30 inches thick)
Oi2--20 to 37 inches; mixed black (5YR 2/1) and dark reddish brown (5YR 2/2), black (5YR 2/1) rubbed; undecomposed organic material (peat); 85 percent fiber, 75 percent fiber, rubbed;
massive; sodium pyrophosphate extract is white (10YR 8/1);
estimated 5 percent mineral material; about 90 percent herbaceous; mildly alkaline; gradual wavy boundary. (16 to 40 inches thick)
Oi3--37 to 80 inches; dark reddish brown (5YR 3/3), unrubbed
and rubbed; undecomposed organic materials (peat); 70 percent
fiber, 55 percent fiber, rubbed; massive; sodium pyrophosphate extract is white (10YR 8/1); estimated 5 percent mineral material; about 90 percent herbaceous, mildly alkaline.
TYPE LOCATION: Lake County, Florida. One mile east of Frank's packing shed and about 250 feet north of Big Drainage Canal. SW1/4NE1/4sec. 34, T. 20 S., R. 26 E.
RANGE IN CHARACTERISTICS: Thickness of the organic material is 52 inches to more than 100 inches. Mean annual soil temperature
ranges from 74 degrees to 77 degrees F. Soil reaction ranges from medium acid to moderately alkaline by Hellige-Troup method or more than pH 4.5 in 0.01M CaC12.
The surface layer has fibric, hemic, or sapric organic materials depending on past history and degree of decomposition. It is
black (5YR 2/1; N 2/ ; 10YR 2/1), dark reddish brown (5YR 2/2,
3/2, 3/3, 3/4), very dark brown (10YR 2/2), dark brown (10YR 3/3),
or very dark grayish brown (10YR 3/2). Some pedons have a thin
layer of hemic or sapric material below the Oap horizon. Where present, total thickness of hemic layers is not more than 13
inches and total thickness of sapric layers is 6 inches or less.
The Oi horizons are more than 75 percent fiber unrubbed or more
than 40 percent fiber rubbed and a sodium pyrophosphate extract
color of light gray (10YR 7/1, 7/2) or white (10YR 8/1, 8/2).
Fiber is normally of herbaceous origin, but in many pedons about
25 percent of the mass is of woody origin. Color of the Oi
horizons is in hue 5YR to 10YR, value 2 to 5, chroma 1 to 6.
Color is dependent on the kind of plant material.
COMPETING SERIES: These are the Allemands,
Brighton, Carlin, Dorovan, Everglades, Hontoon, Istokpoga,
Maurepas, Micco, Ocoee, Okeechobee, Okeelanta, Pamlico, Ponzer, Samsula, and Tomoka series. Allemands, Carlin, Dorovan, Maurepas, Pamlico, and Ponzer soils have temperatures of 72 degrees F. or
less at depths of 20 inches. All of these but Carlin and Micco
soils have sapric material below 12 inches. Carlin soils have a layer of water and hemic material in the control section.
Brighton, Hontoon, Ocoee, and Samsula soils are more acid. In addition, Ocoee and Tomoka soils have a mineral layer 12 inches or more thick within the control section. Everglades soils are dominated by hemic material within the control section.
Okeechobee soils have sapric material over hemic material.
Okeelanta soils have sapric organic materials over mineral
materials at a depth of 16 to 40 inches. Istokpoga soils are comprised of woody organic materials.
GEOGRAPHIC SETTING: Montverde soils are in depressions and fresh water marshes and swamps. Gradients are less than 2 percent. These
soils are dominantly the remains of fibrous, nonwoody plants, influenced by the underlying alkaline materials. The climate is humid and warm. Near the type location, precipitation averages
about 55 inches and mean annual air temperature is about 75
degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Everglades, Okeechobee, and Okeelanta series, and the Astor, Chobee, Delray, Felda, Manatee, and Pompano series. All of the latter soils are
of mineral origin and occur adjacent to the organic soils.
DRAINAGE AND PERMEABILITY: Montverde soils are very poorly
drained. Runoff is slow. Internal drainage is impeded by a very shallow water table. Permeability is rapid. In drained areas, an efficient water control system regulates the water table according
to the plant needs. In undrained areas, the water table is at or
on the surface of the soil except during extended dry periods.
USE AND VEGETATION: Large areas are cleared and used for corn, truck, and sod crops and improved pasture. Undeveloped areas are
used for water storage and as a wildlife habitat. Native
vegetation is sawgrass, lilies, sedges, and other water tolerant fibrous, nonwoody plants. Cypress, red and white bay, maple, pond pine, and gum are common tree species.
DISTRIBUTION AND EXTENT: Central and southern Florida. The
series is of moderate extent.
SERIES ESTABLISHED: Lake County, Florida; 1970.
REMARKS: Previously classified as Bog soils.
