Lateritic Soils

Lateritic Soils

 

soils of equatorial and tropical rain forests, characterized by low silica content, high aluminum and iron content, insignificant content of alkalies and alkaline earths, acid reaction, and low cation and high anion absorptive capacity. Since the late 1950’s lateritic soils have more often been referred to as ferralitic soils, and the term “lateritic” has been used for soils that have a horizon of laterite in their profile.

The formations encountered from the surface to the depth were various lateritic formations (lateritic soils, laterites) with high resistivity values (> 2000 Ohm.m), a gneissic weathered/fractured arena with low resistivity values (< 850 Ohm.m) which represents the aquifer formation and the gneissic basement.
For example, Chisholm's Wattle (Acacia chisolmii, [C.sub.3] plant, [N.sub.2]-fixing legume shrub) and Spinifex (Triodia spp., [C.sub.4] grass) are two keystone native plant species widely present on stony and lateritic soils in the colluvial and well drained land of Mt Isa region (North-west, Queensland, Australia) (Specht and Specht 1999; Fox et al.

The Pinus cubensis, simply called Pino, grows in the mountains of northeastern Cuba, over higher rainy slopes covered with red lateritic soils. Its thickets mixed with tropical forests create some fabulous, though vulnerable, landscapes.
1c) showed loamy sand and sandy loam A horizons over B horizons typical of lateritic soils, which texture as sandy-loam to sandy clay loam when finely ground but in their native state are cemented with sesquioxides and contain dense ironstone gravel layers (>60% v/v) at the upper margin of the B horizon.
The lateritic soils become compact and harden, so that after only a few years of cultivation such areas are as hard as concrete and further cultivation or revegetation is impossible.
