  1. BAHAN KAJIAN MK. DASAR ILMU TANAH TANAH INCEPTISOLS Inceptisols (from Latininceptum, "beginning") are soils that exhibit minimal horizon development. Inceptisols are divided into 7 suborders: Aquepts, Anthrepts, Gelepts, Cryepts, Ustepts, Xerepts, and Udepts.

Climate which inhibits soil development such as low temperatures or low precipitation favors the development of Inceptisols. The suborder of Aquepts requires higher soil moisture conditions compared to the other suborders of Inceptisols. Vegetasi Inceptisolsditemukanpadaekosistemhutan, padangrumputdanlahanpertanian.

  7. TANAH INCEPTISOLS PROSES PEMBENTUKAN - GENESIS Virtually many pedogenic processes are active to some extent in Inceptisol profiles but none predominates. The genesis of Inceptisols includes multiple pathways depending on the processes occuring on a given landscape and geographic area. Environmental factors can slow down weathering (e.g. low temperatures, low precipitation, or resistant parent material) and soil development to form other soil orders is retarded or even inhibited.

Inceptisols may be also found on alluvial deposits where temporary flooding alters the soil profile due to the deposition of soil particles on the soil surface and the soil profile becomes saturated. For example, Inceptisols in the southern Mississippi River Valey are developed on alluvial deposits. Tabel-air yang dekatdenganpermukaanmendorongproses-prosesreduksioksidabesidanoksidaaluminium.

In landscapes of high base status soils, the associated poorly drained Inceptisols in depression areas usually have higher base status than the surrounding soils. This can be attributed to the enrichment of the low-lying parts of the landscape by lateral processes such as transport of bases attached to soil particles, in surface runoff, or lateral subsurface flow. In some materials saturated with brackish water sulfides may accumulate and sulfuric horizons may be formed. Kalaumengalamioksidasi, biasanyaolehadanya drainage buatan, terbentuklahasamsulfat.

Typically, these soils have an ochric or umbricepipedon over a cambic horizon. The ochricepipedon is generally a light-colored, low organic matter horizon. The umbricepipedon is similar to the mollicepipedon except for having a base saturation less than 50 %. Some poorly drained Inceptisols have a histicepipedon where organic matter content is high. Soils with mollicepipedons are Inceptisols when base saturation at pH 7 is less than 50 % in some horizon between the mollicepipedon and a depth of 180 cm or a lithic or paralithic contact if shallower.

  15. TANAH INCEPTISOLS Inceptisolsare young soils that are more developed than entisols. These soils are found in arctic tundra environments, glacial deposits, and relatively recent deposits of stream alluvium. Common characteristics of recognition include immature development of eluviation in the A horizon and illuviation in the B horizon.

They are mostly in the high mountains of the West as well as southern Alaska. The vegetation is mostly conifers or mixed conifers and hardwoods. Most are used as forest or wildlife habitat. Some of the soils, mostly those in Alaska, are used as cropland. Diunduhdari: ………….. 25/2/2013

  19. Subordo yang dominan • Udepts are mainly freely drained Inceptisols that have a udic or perudic moisture regime. They are most extensive in the Appalachian Mountains, on the Allegheny Plateau, in northeastern Minnesota, and in Oregon.

They are in the western part of the United States, mostly in California, Oregon, and Washington. The native vegetation commonly was coniferous forest on the soils with a frigid or mesic temperature regime and shrubs, grasses, and widely spaced trees on the soils with a thermic temperature regime. Most Xerepts are used as forest, cropland, or pasture. Some are used as rangeland or wildlife habitat. Diunduhdari: ………….. 25/2/2013

  21. TANAH INCEPTISOLS Aquepts: They show redoximorphic features and are saturated with water at some period in the year. Aquepts usually have cambic horizons and commonly in the US, they have fragipans. Aquepts are found in the Flood Plains of the Mississippi River Valley, the lacustrine regions in the Midwest, and the lower Coastal Plain along the Atlantic and Gulf Coast. Plaggepts: They have dark brown or black plaggenepipedons. Plaggepts were formed by anthropic activity mainly in Europe and are of small extent.

The presence of a fragipan (e.g. Fragiaquepts, FragicEpiaquepts, or FragicXerochrepts), a duripan (e.g. Durochrepts), or plinthite (e.g. Plinthaquepts) are considered. Carbonates within the soil profile of Inceptisols or a high base status define the Eutrochrepts. Inceptisols low in bases are common on the great group level (e.g. Dystropepts) and on the subgroup level (e.g. DystricEutrochrepts, DystricXerochrepts). Shallow soil profiles are found in several subgroups, for instance, LithicUstochrepts, LithicCryaquepts, and LithicEndoquepts.
